1
00:00:53,300 --> 00:00:55,367
>> narrator: robots perform many
2
00:00:55,367 --> 00:00:57,167
Underwater tasks, which are
3
00:00:57,167 --> 00:00:58,967
Impossible or too risky for
4
00:00:58,967 --> 00:01:00,733
Divers to carry out, like
5
00:01:00,733 --> 00:01:02,533
Collecting samples from the
6
00:01:02,533 --> 00:01:04,267
Ocean floor for scientific
7
00:01:04,267 --> 00:01:06,300
Research, exploring shipwrecks,
8
00:01:06,300 --> 00:01:08,400
Inspecting underwater pipelines,
9
00:01:08,400 --> 00:01:09,833
Searching for planted
10
00:01:09,833 --> 00:01:11,533
Explosives, or recovering
11
00:01:11,533 --> 00:01:15,133
Bodies.
12
00:01:15,133 --> 00:01:16,800
This particular underwater
13
00:01:16,800 --> 00:01:18,367
Robot is designed to find
14
00:01:18,367 --> 00:01:20,200
Unconscious drowning victims.
15
00:01:20,200 --> 00:01:22,133
Recent incidents have shown that
16
00:01:22,133 --> 00:01:23,833
A person recovered within 90
17
00:01:23,833 --> 00:01:25,500
Minutes can survive without
18
00:01:25,500 --> 00:01:27,133
Brain damage when rescuers
19
00:01:27,133 --> 00:01:29,067
Follow a specific resuscitation
20
00:01:29,067 --> 00:01:30,833
Protocol.
21
00:01:30,833 --> 00:01:32,500
The robot uses a protruding,
22
00:01:32,500 --> 00:01:34,200
Interlocking jaw to grab the
23
00:01:34,200 --> 00:01:36,067
Victim by a limb and haul him or
24
00:01:36,067 --> 00:01:37,933
Her to the surface.
25
00:01:37,933 --> 00:01:39,467
Its onboard camera gives
26
00:01:39,467 --> 00:01:41,167
Operators at the surface an
27
00:01:41,167 --> 00:01:42,300
Underwater view.
28
00:01:42,300 --> 00:01:44,100
When the water's too murky to
29
00:01:44,100 --> 00:01:45,900
See anything, video-enhancing
30
00:01:45,900 --> 00:01:47,667
Technology and imaging sonar
31
00:01:47,667 --> 00:01:50,200
Detect the outline of objects.
32
00:01:50,200 --> 00:01:51,967
Several thrusters propel the
33
00:01:51,967 --> 00:01:53,533
Robot through the water.
34
00:01:53,533 --> 00:01:55,167
For each one, technicians
35
00:01:55,167 --> 00:01:57,100
Grease, then position a pair of
36
00:01:57,100 --> 00:01:59,067
O-rings onto end caps that they
37
00:01:59,067 --> 00:02:00,767
Install on each end of the
38
00:02:00,767 --> 00:02:04,100
Thruster housing.
39
00:02:04,100 --> 00:02:05,767
The o-rings seal the end caps,
40
00:02:05,767 --> 00:02:07,433
Keeping water out of the motor
41
00:02:07,433 --> 00:02:10,133
Located inside the housing.
42
00:02:10,133 --> 00:02:11,800
The motor shaft protrudes
43
00:02:11,800 --> 00:02:13,733
Through propeller the end cap.
44
00:02:13,733 --> 00:02:15,667
A mechanical bale secures both
45
00:02:15,667 --> 00:02:17,267
Thruster end caps to the
46
00:02:17,267 --> 00:02:19,733
Housing.
47
00:02:19,733 --> 00:02:21,500
They fill the thruster with
48
00:02:21,500 --> 00:02:22,067
Oil.
49
00:02:22,067 --> 00:02:23,933
This prevents the thruster from
50
00:02:23,933 --> 00:02:25,867
Imploding under pressure as the
51
00:02:25,867 --> 00:02:27,467
Robot descends deeper and
52
00:02:27,467 --> 00:02:28,133
Deeper.
53
00:02:28,133 --> 00:02:29,767
After filling, they draw a
54
00:02:29,767 --> 00:02:31,767
Vacuum to remove any air bubbles
55
00:02:31,767 --> 00:02:33,767
And draw the oil into every nook
56
00:02:33,767 --> 00:02:34,633
And cranny.
57
00:02:34,633 --> 00:02:36,500
Then then install a reservoir,
58
00:02:36,500 --> 00:02:38,967
Which they also fill with oil.
59
00:02:38,967 --> 00:02:40,567
When the underwater pressure
60
00:02:40,567 --> 00:02:42,267
Builds, this backup oil supply
61
00:02:42,267 --> 00:02:43,933
Fills any remaining miniscule
62
00:02:43,933 --> 00:02:45,633
Air gap the vacuum might have
63
00:02:45,633 --> 00:02:47,567
Missed.
64
00:02:47,567 --> 00:02:49,367
They close the reservoir with
65
00:02:49,367 --> 00:02:51,233
A sealing screw to prevent any
66
00:02:51,233 --> 00:02:52,633
Oil from leaking out.
67
00:02:52,633 --> 00:02:54,600
Now they turn their attention to
68
00:02:54,600 --> 00:02:56,467
The thruster's main component,
69
00:02:56,467 --> 00:02:58,267
A two-blade propeller made of
70
00:02:58,267 --> 00:02:59,267
Durable nylon.
71
00:02:59,267 --> 00:03:01,200
It goes on the back end of the
72
00:03:01,200 --> 00:03:03,567
Thrusters.
73
00:03:03,567 --> 00:03:05,500
They install the camera chassis
74
00:03:05,500 --> 00:03:06,567
Onto the robot.
75
00:03:06,567 --> 00:03:08,367
This chassis also carries the
76
00:03:08,367 --> 00:03:09,867
Majority of the robot's
77
00:03:09,867 --> 00:03:11,433
Electronics, such as the
78
00:03:11,433 --> 00:03:12,967
Computer, communications
79
00:03:12,967 --> 00:03:16,967
Equipment, and lighting.
80
00:03:16,967 --> 00:03:18,567
Here they're hooking up the belt
81
00:03:18,567 --> 00:03:20,133
For the tiny motor, which tilts
82
00:03:20,133 --> 00:03:23,733
The camera to look up and down.
83
00:03:23,733 --> 00:03:25,600
They cover the camera chassis
84
00:03:25,600 --> 00:03:27,633
With a transparent, acrylic dome
85
00:03:27,633 --> 00:03:29,233
Called the viewing port.
86
00:03:29,233 --> 00:03:31,233
A cap with an o-ring seal keeps
87
00:03:31,233 --> 00:03:33,900
Water out.
88
00:03:33,900 --> 00:03:35,700
They install the robot's power
89
00:03:35,700 --> 00:03:37,467
Supply at the opposite end of
90
00:03:37,467 --> 00:03:39,300
The robot, then encase it in a
91
00:03:39,300 --> 00:03:41,200
Metal tube, sealed on both sides
92
00:03:41,200 --> 00:03:46,933
With an end cap and an o-ring.
93
00:03:46,933 --> 00:03:48,700
For the thrusters to work at
94
00:03:48,700 --> 00:03:50,600
Maximum efficiency, the robot
95
00:03:50,600 --> 00:03:52,233
Must be neutrally buoyant,
96
00:03:52,233 --> 00:03:54,067
Meaning neither too light nor
97
00:03:54,067 --> 00:03:54,867
Too heavy.
98
00:03:54,867 --> 00:03:56,867
So once the robot is fitted with
99
00:03:56,867 --> 00:03:58,267
All its thrusters and
100
00:03:58,267 --> 00:04:00,300
Electronics, technicians install
101
00:04:00,300 --> 00:04:01,400
The main float.
102
00:04:01,400 --> 00:04:03,267
Certain models have additional
103
00:04:03,267 --> 00:04:04,967
Floats.
104
00:04:04,967 --> 00:04:06,533
They cap each propeller with a
105
00:04:06,533 --> 00:04:07,933
Vented cover called a kort
106
00:04:07,933 --> 00:04:09,700
Nozzle.
107
00:04:09,700 --> 00:04:11,400
This isolates the water flow,
108
00:04:11,400 --> 00:04:12,933
Maximizing the propeller's
109
00:04:12,933 --> 00:04:15,833
Efficiency.
110
00:04:15,833 --> 00:04:17,500
These bumper frames act like
111
00:04:17,500 --> 00:04:18,633
Bumpers on a car.
112
00:04:18,633 --> 00:04:20,500
They absorb the force of impact,
113
00:04:20,500 --> 00:04:22,067
Protecting the robot from
114
00:04:22,067 --> 00:04:23,533
Damage when it encounters
115
00:04:23,533 --> 00:04:26,900
Underwater objects.
116
00:04:26,900 --> 00:04:28,800
The bumper frames also serve as
117
00:04:28,800 --> 00:04:30,767
A structure to attach lights and
118
00:04:30,767 --> 00:04:32,533
Other components, as well as
119
00:04:32,533 --> 00:04:34,433
Specialized tools, such as that
120
00:04:34,433 --> 00:04:36,300
Quick-release jaw, which grabs
121
00:04:36,300 --> 00:04:43,067
The victim by a limb.
122
00:04:43,067 --> 00:04:44,833
They install the jaw at an angle
123
00:04:44,833 --> 00:04:46,400
So that it doesn't block the
124
00:04:46,400 --> 00:04:51,300
Camera's view.
125
00:04:51,300 --> 00:04:52,700
Now the sonar unit.
126
00:04:52,700 --> 00:04:54,600
It also mounts to the bumper
127
00:04:54,600 --> 00:04:55,300
Frames.
128
00:04:55,300 --> 00:04:57,400
The sonar projects a 130-degree
129
00:04:57,400 --> 00:04:59,400
Left-to-right 3-d image onto a
130
00:04:59,400 --> 00:05:01,567
Monitor at the surface, showing
131
00:05:01,567 --> 00:05:03,533
The outline of objects around
132
00:05:03,533 --> 00:05:09,933
The robot.
133
00:05:09,933 --> 00:05:11,600
Finally, at the top, they
134
00:05:11,600 --> 00:05:13,400
Install a strobe light -- a
135
00:05:13,400 --> 00:05:15,167
Flashing beacon that tells
136
00:05:15,167 --> 00:05:17,233
Rescuers on the surface exactly
137
00:05:17,233 --> 00:05:23,967
Where the robot is.
138
00:05:23,967 --> 00:05:25,900
Every underwater robot goes out
139
00:05:25,900 --> 00:05:27,800
For a test drive.
140
00:05:27,800 --> 00:05:29,533
They submerge it in a tank,
141
00:05:29,533 --> 00:05:31,467
Which is essentially an aquarium
142
00:05:31,467 --> 00:05:33,067
Inhabited by fish of the
143
00:05:33,067 --> 00:05:35,533
Stick-on variety.
144
00:05:35,533 --> 00:05:37,433
These inanimate creatures adhere
145
00:05:37,433 --> 00:05:39,200
To the glass, provide colorful
146
00:05:39,200 --> 00:05:40,833
Images on which testers can
147
00:05:40,833 --> 00:05:45,067
Focus and unfocus the camera.
148
00:05:45,067 --> 00:05:46,900
From there on in, the first
149
00:05:46,900 --> 00:05:48,900
Mission in open water awaits.
150
00:06:01,133 --> 00:06:03,133
>> narrator: there are many ways
151
00:06:03,133 --> 00:06:05,067
To make lasagna, but no matter
152
00:06:05,067 --> 00:06:07,067
How it stacks up, people seem to
153
00:06:07,067 --> 00:06:09,067
Never get enough of this classic
154
00:06:09,067 --> 00:06:10,067
Italian dish.
155
00:06:10,067 --> 00:06:11,967
Popular in italy for centuries,
156
00:06:11,967 --> 00:06:13,433
Its appeals transcends
157
00:06:13,433 --> 00:06:15,067
Boundaries and cultures.
158
00:06:15,067 --> 00:06:16,733
Who anywhere can resist all
159
00:06:16,733 --> 00:06:23,900
Those layers of flavor?
160
00:06:23,900 --> 00:06:25,733
Ruffled, flat noodles define
161
00:06:25,733 --> 00:06:26,433
Lasagna.
162
00:06:26,433 --> 00:06:27,967
They give it structure.
163
00:06:27,967 --> 00:06:29,700
In between the layers, the
164
00:06:29,700 --> 00:06:31,400
Possibilities are endless.
165
00:06:31,400 --> 00:06:33,333
Ingredients vary, depending on
166
00:06:33,333 --> 00:06:35,767
The recipe.
167
00:06:35,767 --> 00:06:37,567
For a veggie lasagna, things
168
00:06:37,567 --> 00:06:39,500
Start off with sautéed onions,
169
00:06:39,500 --> 00:06:44,767
Seasoned with pepper and salt.
170
00:06:44,767 --> 00:06:46,833
They add pureed tomatoes to the
171
00:06:46,833 --> 00:06:47,833
Pungent mix.
172
00:06:47,833 --> 00:06:49,867
Blades stir the ingredients as
173
00:06:49,867 --> 00:06:52,067
They simmer in this steam-heated
174
00:06:52,067 --> 00:06:55,800
Mixer, and in no time, they have
175
00:06:55,800 --> 00:06:58,700
A full-body tomato sauce.
176
00:06:58,700 --> 00:07:00,667
They pump the tomato sauce into
177
00:07:00,667 --> 00:07:01,633
Lasagna tubs.
178
00:07:01,633 --> 00:07:03,400
This saucy base is the first
179
00:07:03,400 --> 00:07:05,133
Layer of flavor, but it also
180
00:07:05,133 --> 00:07:06,833
Serves a practical purpose,
181
00:07:06,833 --> 00:07:08,533
Preventing the noodles from
182
00:07:08,533 --> 00:07:10,333
Sticking to the bottom of the
183
00:07:10,333 --> 00:07:11,633
Tray during baking.
184
00:07:11,633 --> 00:07:13,433
Workers arrange the broad and
185
00:07:13,433 --> 00:07:15,233
Crinkled lasagna noodles over
186
00:07:15,233 --> 00:07:16,067
The sauce.
187
00:07:16,067 --> 00:07:17,767
These noodles have been made
188
00:07:17,767 --> 00:07:19,700
From a blend of whole grain and
189
00:07:19,700 --> 00:07:21,500
Semolina flours for a texture
190
00:07:21,500 --> 00:07:24,700
That's firm, yet tender.
191
00:07:24,700 --> 00:07:26,633
Now for the filling ingredients.
192
00:07:26,633 --> 00:07:28,367
This factory lasagna will be
193
00:07:28,367 --> 00:07:29,900
Made of roasted, organic
194
00:07:29,900 --> 00:07:30,900
Vegetables.
195
00:07:30,900 --> 00:07:33,167
They include chunks of broccoli
196
00:07:33,167 --> 00:07:35,233
And uniformly mixed peppers,
197
00:07:35,233 --> 00:07:37,433
Onions, carrots, zucchini, and
198
00:07:37,433 --> 00:07:40,800
Mushrooms.
199
00:07:40,800 --> 00:07:42,467
They load the sliced and diced
200
00:07:42,467 --> 00:07:43,733
Veggies into the next
201
00:07:43,733 --> 00:07:46,267
Steam-heated mixer.
202
00:07:46,267 --> 00:07:48,233
The blades swing into action to
203
00:07:48,233 --> 00:07:50,067
Stir the ingredients as they
204
00:07:50,067 --> 00:07:51,067
Brown in oil.
205
00:07:51,067 --> 00:07:52,933
This causes the natural sugars
206
00:07:52,933 --> 00:07:54,933
To break down and the vegetables
207
00:07:54,933 --> 00:07:56,200
To become sweeter.
208
00:07:56,200 --> 00:07:58,067
Creamy mozzarella cheese will
209
00:07:58,067 --> 00:08:00,067
Offset the sugary taste of the
210
00:08:00,067 --> 00:08:00,733
Veggies.
211
00:08:00,733 --> 00:08:02,300
They add the caramelized
212
00:08:02,300 --> 00:08:03,733
Veggies, the shredded
213
00:08:03,733 --> 00:08:05,400
Mozzarella, and more pasta
214
00:08:05,400 --> 00:08:07,367
Noodles, building the layers of
215
00:08:07,367 --> 00:08:08,067
Flavor.
216
00:08:08,067 --> 00:08:12,633
And there's a lot more to come.
217
00:08:12,633 --> 00:08:14,467
Over in another steam-heated
218
00:08:14,467 --> 00:08:16,333
Mixer, a combination of milk,
219
00:08:16,333 --> 00:08:18,333
Oil, and rice flour is on a low
220
00:08:18,333 --> 00:08:20,767
Boil.
221
00:08:20,767 --> 00:08:22,067
Paddles distribute the
222
00:08:22,067 --> 00:08:23,567
Ingredients, and the sauce
223
00:08:23,567 --> 00:08:26,867
Begins to thicken.
224
00:08:26,867 --> 00:08:28,400
Shredded monterey jack and
225
00:08:28,400 --> 00:08:30,100
Parmesan cheeses will enhance
226
00:08:30,100 --> 00:08:31,833
The creaminess and add another
227
00:08:31,833 --> 00:08:35,967
Dimension of flavor.
228
00:08:35,967 --> 00:08:38,200
Next, a serious dash of nutmeg
229
00:08:38,200 --> 00:08:40,433
And another one of salt spices
230
00:08:40,433 --> 00:08:42,667
It up.
231
00:08:42,667 --> 00:08:44,633
And after more stirring action,
232
00:08:44,633 --> 00:08:46,333
The white sauce is velvety
233
00:08:46,333 --> 00:08:47,933
Smooth and substantially
234
00:08:47,933 --> 00:08:50,600
Thicker.
235
00:08:50,600 --> 00:08:52,300
Meanwhile, a worker shovels
236
00:08:52,300 --> 00:08:53,700
Crust into a grinder.
237
00:08:53,700 --> 00:08:55,500
The crusts are broken pieces
238
00:08:55,500 --> 00:08:57,333
From a pizza production line,
239
00:08:57,333 --> 00:08:59,133
And they have been dried to a
240
00:08:59,133 --> 00:09:01,067
Specific consistency, so they
241
00:09:01,067 --> 00:09:03,867
Should grind up nicely.
242
00:09:03,867 --> 00:09:05,667
A spiraling blade turns the
243
00:09:05,667 --> 00:09:07,667
Crusts into uniform crumbs -- a
244
00:09:07,667 --> 00:09:09,400
Classic lasagna topping --
245
00:09:09,400 --> 00:09:11,367
Adding a bit of crunch to the
246
00:09:11,367 --> 00:09:15,867
Recipe.
247
00:09:15,867 --> 00:09:17,733
With these final ingredients,
248
00:09:17,733 --> 00:09:19,467
They're ready to pile it on
249
00:09:19,467 --> 00:09:20,067
Thick.
250
00:09:20,067 --> 00:09:21,567
As the layering process
251
00:09:21,567 --> 00:09:23,333
Continues, this meal really
252
00:09:23,333 --> 00:09:24,400
Comes together.
253
00:09:24,400 --> 00:09:26,100
The cream sauce and bread
254
00:09:26,100 --> 00:09:27,733
Crumbs are the finishing
255
00:09:27,733 --> 00:09:31,900
Touches.
256
00:09:31,900 --> 00:09:33,300
With numerous sous chefs
257
00:09:33,300 --> 00:09:35,067
Involved, things happen a whole
258
00:09:35,067 --> 00:09:36,833
Lot faster here than on the home
259
00:09:36,833 --> 00:09:38,300
Front.
260
00:09:38,300 --> 00:09:40,267
They assemble 48 single-serving
261
00:09:40,267 --> 00:09:42,100
Lasagna dishes per minute at
262
00:09:42,100 --> 00:09:45,700
This factory...
263
00:09:45,700 --> 00:09:47,433
Then place them on trays and
264
00:09:47,433 --> 00:09:49,300
Transfer them to a specialized
265
00:09:49,300 --> 00:09:53,767
Freezer.
266
00:09:53,767 --> 00:09:55,767
This is a blast freezer, which
267
00:09:55,767 --> 00:09:57,400
Is also known as a shock
268
00:09:57,400 --> 00:09:58,133
Freezer.
269
00:09:58,133 --> 00:10:00,133
It brings down the temperature
270
00:10:00,133 --> 00:10:01,667
Of foods very rapidly,
271
00:10:01,667 --> 00:10:05,667
Preserving the flavor.
272
00:10:05,667 --> 00:10:07,533
On the next shift, they remove
273
00:10:07,533 --> 00:10:09,433
The lasagnas from the freezer.
274
00:10:09,433 --> 00:10:12,700
It's time to wrap up this meal.
275
00:10:12,700 --> 00:10:14,500
The lasagnas ride a conveyer
276
00:10:14,500 --> 00:10:17,067
Through a curtain of cellophane.
277
00:10:17,067 --> 00:10:18,667
An automated system heat-seals
278
00:10:18,667 --> 00:10:22,733
The wrap around the trays.
279
00:10:22,733 --> 00:10:24,433
Things move swiftly to prevent
280
00:10:24,433 --> 00:10:27,867
Thawing.
281
00:10:27,867 --> 00:10:29,700
They package 75 lasagnas per
282
00:10:29,700 --> 00:10:31,600
Minute on this line, and then
283
00:10:31,600 --> 00:10:33,400
It's back in the freezer to
284
00:10:33,400 --> 00:10:38,633
Await shipping.
285
00:10:38,633 --> 00:10:40,533
Once something only mama made,
286
00:10:40,533 --> 00:10:42,567
Now workers and machines team up
287
00:10:42,567 --> 00:10:44,600
To mass-produce this traditional
288
00:10:44,600 --> 00:10:50,700
Comfort food.
289
00:10:50,700 --> 00:10:52,600
So at mealtime, one only has to
290
00:10:52,600 --> 00:10:54,367
Pop the frozen lasagna in the
291
00:10:54,367 --> 00:10:56,700
Oven, and then mangia.
292
00:11:08,767 --> 00:11:10,300
>> narrator: from the home
293
00:11:10,300 --> 00:11:12,067
Workshop to the factory floor,
294
00:11:12,067 --> 00:11:13,800
The band saw is one of the most
295
00:11:13,800 --> 00:11:15,400
Popular power tools around.
296
00:11:15,400 --> 00:11:17,100
It's called a band saw because
297
00:11:17,100 --> 00:11:18,833
The blade is a metal band with
298
00:11:18,833 --> 00:11:20,667
Teeth that moves continuously in
299
00:11:20,667 --> 00:11:22,200
A loop around two or three
300
00:11:22,200 --> 00:11:23,867
Rotating wheels.
301
00:11:23,867 --> 00:11:25,800
It can make straight, curved,
302
00:11:25,800 --> 00:11:31,433
And angled cuts.
303
00:11:31,433 --> 00:11:33,400
This is an industrial band saw,
304
00:11:33,400 --> 00:11:35,400
Designed to cut wood, aluminum,
305
00:11:35,400 --> 00:11:37,433
And composite materials, such as
306
00:11:37,433 --> 00:11:40,167
Plexiglass.
307
00:11:40,167 --> 00:11:41,933
It can cut pieces up to 12
308
00:11:41,933 --> 00:11:43,900
Inches thick and can divide a
309
00:11:43,900 --> 00:11:45,967
Board up to 40 inches wide into
310
00:11:45,967 --> 00:11:49,167
Two equal sections.
311
00:11:49,167 --> 00:11:51,367
The tabletop tilts to a maximum
312
00:11:51,367 --> 00:11:54,900
45 degrees for angled cuts.
313
00:11:54,900 --> 00:11:57,867
It's made of sturdy cast iron.
314
00:11:57,867 --> 00:11:59,533
The band-saw manufacturer
315
00:11:59,533 --> 00:12:01,333
Purchases it from a nearby
316
00:12:01,333 --> 00:12:03,133
Foundry, then uses a rotary
317
00:12:03,133 --> 00:12:05,167
Grinder to make the surface, as
318
00:12:05,167 --> 00:12:07,167
We can see on the right, smooth
319
00:12:07,167 --> 00:12:11,433
And shiny.
320
00:12:11,433 --> 00:12:13,433
One of the saw's key components
321
00:12:13,433 --> 00:12:15,200
Is this lower bearing case.
322
00:12:15,200 --> 00:12:17,233
It links the motor to the lower
323
00:12:17,233 --> 00:12:19,167
Of two cast-iron wheels, which
324
00:12:19,167 --> 00:12:22,367
Turn the saw blade.
325
00:12:22,367 --> 00:12:24,067
Workers will later mount that
326
00:12:24,067 --> 00:12:25,667
Lower wheel on one end of the
327
00:12:25,667 --> 00:12:28,533
Bearing case shaft.
328
00:12:28,533 --> 00:12:30,167
Now, on the opposite end of the
329
00:12:30,167 --> 00:12:31,600
Shaft, they mount the drive
330
00:12:31,600 --> 00:12:34,367
Pulley.
331
00:12:34,367 --> 00:12:36,300
The motor will rotate the drive
332
00:12:36,300 --> 00:12:38,133
Pulley, turning the shaft and
333
00:12:38,133 --> 00:12:40,067
Consequently the lower wheel on
334
00:12:40,067 --> 00:12:41,867
The opposite end, which moves
335
00:12:41,867 --> 00:12:43,800
The saw blade looped around the
336
00:12:43,800 --> 00:12:49,333
Lower and upper wheels.
337
00:12:49,333 --> 00:12:50,900
Those cast-iron wheels,
338
00:12:50,900 --> 00:12:52,967
Meanwhile, need a rubber edge to
339
00:12:52,967 --> 00:12:55,067
Ensure the blade moves smoothly
340
00:12:55,067 --> 00:12:57,933
And without slipping.
341
00:12:57,933 --> 00:12:59,600
Workers position a guide over
342
00:12:59,600 --> 00:13:01,300
The first wheel, then slip a
343
00:13:01,300 --> 00:13:08,267
Rubber band onto the guide.
344
00:13:08,267 --> 00:13:10,133
Next, they coat both the edge of
345
00:13:10,133 --> 00:13:12,067
The wheel and the rubber band on
346
00:13:12,067 --> 00:13:13,800
The guide with contact cement
347
00:13:13,800 --> 00:13:22,367
Adhesive.
348
00:13:22,367 --> 00:13:24,067
Then they carefully pull the
349
00:13:24,067 --> 00:13:25,767
Rubber band off the guide, flip
350
00:13:25,767 --> 00:13:27,367
It over, and press the glued
351
00:13:27,367 --> 00:13:29,100
Side against the glued surface
352
00:13:29,100 --> 00:13:31,067
Of the wheel.
353
00:13:39,267 --> 00:13:40,833
The first wheel now has a
354
00:13:40,833 --> 00:13:41,933
Rubberized edge.
355
00:13:41,933 --> 00:13:43,800
They repeat the same procedures
356
00:13:43,800 --> 00:13:46,133
For the second wheel.
357
00:13:46,133 --> 00:13:47,600
In the meantime, another
358
00:13:47,600 --> 00:13:49,367
Department has welded the band
359
00:13:49,367 --> 00:13:51,633
Saw's steel steal cabinet.
360
00:13:51,633 --> 00:13:53,300
After the cabinet gets a paint
361
00:13:53,300 --> 00:13:54,933
Job, workers begin installing
362
00:13:54,933 --> 00:13:57,533
The various components, among
363
00:13:57,533 --> 00:13:59,067
Them the support assembly for
364
00:13:59,067 --> 00:14:05,333
The upper wheel.
365
00:14:05,333 --> 00:14:06,733
Behind the wall on which they
366
00:14:06,733 --> 00:14:08,133
Mount the upper wheel, down at
367
00:14:08,133 --> 00:14:09,367
The bottom and protruding
368
00:14:09,367 --> 00:14:10,833
Forward through the hole in the
369
00:14:10,833 --> 00:14:12,267
Wall, they install the support
370
00:14:12,267 --> 00:14:15,333
For the lower wheel.
371
00:14:15,333 --> 00:14:17,200
This support is the shaft of the
372
00:14:17,200 --> 00:14:18,867
Lower bearing case, the side
373
00:14:18,867 --> 00:14:24,367
Opposite the drive pulley.
374
00:14:24,367 --> 00:14:26,067
After mounting the lower wheel,
375
00:14:26,067 --> 00:14:27,533
They move behind the wall,
376
00:14:27,533 --> 00:14:29,267
Install an electric motor right
377
00:14:29,267 --> 00:14:30,867
Below the lower bearing case,
378
00:14:30,867 --> 00:14:32,633
And link the two with a pair of
379
00:14:32,633 --> 00:14:34,200
Belts.
380
00:14:34,200 --> 00:14:36,167
So now when the motor runs, the
381
00:14:36,167 --> 00:14:38,067
Pulley rotates, and the lower
382
00:14:38,067 --> 00:14:39,467
Wheel turns.
383
00:14:39,467 --> 00:14:41,167
Next, they bolt in the
384
00:14:41,167 --> 00:14:42,067
Tabletop.
385
00:14:42,067 --> 00:14:44,267
It tilts on trunnions -- pairs
386
00:14:44,267 --> 00:14:46,600
Of mating, cast-iron supports --
387
00:14:46,600 --> 00:14:48,667
One attached to the table's
388
00:14:48,667 --> 00:14:50,200
Underside, the other to the
389
00:14:50,200 --> 00:14:53,300
Cabinet's table frame.
390
00:14:53,300 --> 00:14:55,200
Now for the most critical part
391
00:14:55,200 --> 00:14:56,733
Of the assembly process.
392
00:14:56,733 --> 00:14:58,367
Workers use this jig as a
393
00:14:58,367 --> 00:15:00,200
Precision guide to align the
394
00:15:00,200 --> 00:15:00,867
Wheels.
395
00:15:00,867 --> 00:15:02,633
The wheels must be perfectly
396
00:15:02,633 --> 00:15:04,567
Balanced to keep the saw blades
397
00:15:04,567 --> 00:15:07,533
Stable while it's cutting.
398
00:15:07,533 --> 00:15:09,333
Once the alignment's complete,
399
00:15:09,333 --> 00:15:11,233
Workers remove the jig and loop
400
00:15:11,233 --> 00:15:13,067
The steel saw blade around the
401
00:15:13,067 --> 00:15:18,533
Two wheels.
402
00:15:18,533 --> 00:15:20,067
They adjust the blade to the
403
00:15:20,067 --> 00:15:21,400
Correct tautness by simply
404
00:15:21,400 --> 00:15:23,067
Setting the tension gauge to the
405
00:15:23,067 --> 00:15:32,333
Width of the blade.
406
00:15:32,333 --> 00:15:34,067
And finally, the last step.
407
00:15:34,067 --> 00:15:35,967
Above the tabletop, they mount
408
00:15:35,967 --> 00:15:41,200
Bearings which guide the blade.
409
00:15:41,200 --> 00:15:42,900
Without these, the blade would
410
00:15:42,900 --> 00:15:44,633
Wobble or drift offline due to
411
00:15:44,633 --> 00:15:46,433
The force of cutting through the
412
00:15:46,433 --> 00:15:52,267
Wood or other hard material.
413
00:15:52,267 --> 00:15:54,167
Now just a final check to ensure
414
00:15:54,167 --> 00:15:55,867
Everything runs smoothly and
415
00:15:55,867 --> 00:15:57,667
Make absolutely sure this band
416
00:15:57,667 --> 00:15:59,567
Saw is up to speed when it comes
417
00:15:59,567 --> 00:16:01,067
To cutting construction
418
00:16:01,067 --> 00:16:02,967
Materials.
419
00:16:16,533 --> 00:16:18,433
>> narrator: whether skiing down
420
00:16:18,433 --> 00:16:20,167
A snowy slope or hiking up a
421
00:16:20,167 --> 00:16:21,967
Rocky one, pointed metal poles
422
00:16:21,967 --> 00:16:23,900
Can provide much needed support.
423
00:16:23,900 --> 00:16:25,700
They add balance and rhythm to
424
00:16:25,700 --> 00:16:27,067
Both experiences.
425
00:16:27,067 --> 00:16:28,767
Aluminum poles were first
426
00:16:28,767 --> 00:16:30,133
Developed for skiing.
427
00:16:30,133 --> 00:16:32,067
In recent years, the concept has
428
00:16:32,067 --> 00:16:33,700
Been modified for trekking
429
00:16:33,700 --> 00:16:38,200
Poles.
430
00:16:38,200 --> 00:16:39,900
Ski poles and trekking poles
431
00:16:39,900 --> 00:16:41,433
Look alike, but there are
432
00:16:41,433 --> 00:16:42,800
Important differences.
433
00:16:42,800 --> 00:16:44,533
Ski poles are one set length,
434
00:16:44,533 --> 00:16:46,167
While trekking poles can be
435
00:16:46,167 --> 00:16:49,233
Extended as needed.
436
00:16:49,233 --> 00:16:50,867
Ski poles begin with hollow
437
00:16:50,867 --> 00:16:52,633
Shafts made of aircraft-grade
438
00:16:52,633 --> 00:16:53,367
Aluminum.
439
00:16:53,367 --> 00:16:55,067
They bake them for up to 12
440
00:16:55,067 --> 00:16:57,700
Hours to stiffen the metal.
441
00:16:57,700 --> 00:16:59,600
Next, the poles travel between
442
00:16:59,600 --> 00:17:01,700
Rollers, which apply pressure to
443
00:17:01,700 --> 00:17:03,500
Straighten them.
444
00:17:03,500 --> 00:17:05,067
The stiffening of the metal
445
00:17:05,067 --> 00:17:06,333
Beforehand is key here.
446
00:17:06,333 --> 00:17:07,867
It ensures that the aluminum
447
00:17:07,867 --> 00:17:09,233
Doesn't snap during this
448
00:17:09,233 --> 00:17:13,167
Critical straightening.
449
00:17:13,167 --> 00:17:14,700
They insert one end of the
450
00:17:14,700 --> 00:17:16,333
Ski-pole shaft into a device
451
00:17:16,333 --> 00:17:17,833
That squeezes it down to
452
00:17:17,833 --> 00:17:25,100
Precisely tapered dimensions.
453
00:17:25,100 --> 00:17:26,700
It's a shape that will better
454
00:17:26,700 --> 00:17:28,267
Resist breakage and will also
455
00:17:28,267 --> 00:17:30,967
Make the pole easier to swing.
456
00:17:30,967 --> 00:17:32,567
An automated cutting tool
457
00:17:32,567 --> 00:17:34,400
Spirals into the shaft to even
458
00:17:34,400 --> 00:17:37,100
The jagged edge.
459
00:17:37,100 --> 00:17:38,600
Another cutter spins around the
460
00:17:38,600 --> 00:17:40,133
Outside of the wider end of the
461
00:17:40,133 --> 00:17:43,933
Pole to trim it.
462
00:17:43,933 --> 00:17:46,067
Next, a machine punches a little
463
00:17:46,067 --> 00:17:48,267
Hole in that wider end.
464
00:17:48,267 --> 00:17:49,767
The hole will serve as a guide
465
00:17:49,767 --> 00:17:51,233
During the stenciling of the
466
00:17:51,233 --> 00:17:52,800
Trade name and artwork onto the
467
00:17:52,800 --> 00:17:55,167
Exterior.
468
00:17:55,167 --> 00:17:56,733
With the ski poles tapered and
469
00:17:56,733 --> 00:17:58,100
Trimmed, they head into an
470
00:17:58,100 --> 00:18:00,300
Inspection station.
471
00:18:00,300 --> 00:18:02,167
A supervisor scrutinizes each
472
00:18:02,167 --> 00:18:02,633
One.
473
00:18:02,633 --> 00:18:04,500
Once he gives them the thumbs
474
00:18:04,500 --> 00:18:07,133
Up, they're ready for sanding.
475
00:18:07,133 --> 00:18:09,067
The ski poles spin between two
476
00:18:09,067 --> 00:18:10,967
Sanding belts to remove dusty
477
00:18:10,967 --> 00:18:13,067
Residue and rough up the surface
478
00:18:13,067 --> 00:18:15,167
So that the paint will adhere.
479
00:18:15,167 --> 00:18:16,833
The poles now twirl on an
480
00:18:16,833 --> 00:18:18,667
Overhead rail as a spray gun
481
00:18:18,667 --> 00:18:24,067
Applies the paint.
482
00:18:24,067 --> 00:18:25,933
An automated tool then squeegees
483
00:18:25,933 --> 00:18:27,467
Paint through stencils to
484
00:18:27,467 --> 00:18:29,233
Transfer designs and lettering
485
00:18:29,233 --> 00:18:32,067
Onto the poles.
486
00:18:32,067 --> 00:18:33,833
Each pass of the squeegee-like
487
00:18:33,833 --> 00:18:35,733
Tool applies a different color,
488
00:18:35,733 --> 00:18:37,633
And this layering effect builds
489
00:18:37,633 --> 00:18:40,100
Up the designs.
490
00:18:40,100 --> 00:18:42,067
The poles now head towards an
491
00:18:42,067 --> 00:18:42,933
Acid bath.
492
00:18:42,933 --> 00:18:44,900
An electrical current ripples
493
00:18:44,900 --> 00:18:46,667
Through the acid solution.
494
00:18:46,667 --> 00:18:48,800
This causes the poles to oxidize
495
00:18:48,800 --> 00:18:50,833
For a scratch-resistant finish
496
00:18:50,833 --> 00:18:57,233
Called anodizing.
497
00:18:57,233 --> 00:18:58,800
Meanwhile, on the trekking
498
00:18:58,800 --> 00:19:00,267
Poles' production line,
499
00:19:00,267 --> 00:19:02,067
Machinery inserts long-wired,
500
00:19:02,067 --> 00:19:03,500
Bristled brushes into the
501
00:19:03,500 --> 00:19:04,467
Various shaft.
502
00:19:04,467 --> 00:19:05,933
This roughs up the inner
503
00:19:05,933 --> 00:19:06,567
Surface.
504
00:19:06,567 --> 00:19:08,400
It's a step that will enable an
505
00:19:08,400 --> 00:19:10,100
Expander device to grip it to
506
00:19:10,100 --> 00:19:12,833
Extend the poles.
507
00:19:12,833 --> 00:19:14,433
Next, a spray gun coats some
508
00:19:14,433 --> 00:19:16,067
Unfinished poles with clear
509
00:19:16,067 --> 00:19:18,100
Lacquer.
510
00:19:18,100 --> 00:19:19,833
The owner of the factory now
511
00:19:19,833 --> 00:19:21,700
Surveys a lineup of ski poles.
512
00:19:21,700 --> 00:19:23,600
He's on the lookout for smudges
513
00:19:23,600 --> 00:19:25,533
Or other flaws.
514
00:19:25,533 --> 00:19:27,267
They meet his approval, and so
515
00:19:27,267 --> 00:19:30,167
It's on to the next step.
516
00:19:30,167 --> 00:19:32,067
A carriage moves each ski pole
517
00:19:32,067 --> 00:19:33,900
Forward towards a carbide tip
518
00:19:33,900 --> 00:19:35,667
And presses the tip into the
519
00:19:35,667 --> 00:19:40,167
Tapered end.
520
00:19:40,167 --> 00:19:41,900
With this tough tip in place,
521
00:19:41,900 --> 00:19:43,767
The ski pole is now equipped to
522
00:19:43,767 --> 00:19:48,200
Pierce any hard snow pack.
523
00:19:48,200 --> 00:19:49,600
Next, a worker slides rubber
524
00:19:49,600 --> 00:19:51,200
Grips onto the handle end of the
525
00:19:51,200 --> 00:19:56,100
Poles.
526
00:19:56,100 --> 00:19:57,800
Like a big automated fist, a
527
00:19:57,800 --> 00:19:59,633
Hydraulic mechanism shoves the
528
00:19:59,633 --> 00:20:01,533
Grip more tightly onto the pole.
529
00:20:10,200 --> 00:20:11,800
There are many different kinds
530
00:20:11,800 --> 00:20:13,433
Of grips, each with a different
531
00:20:13,433 --> 00:20:15,033
Look and feel depending on the
532
00:20:15,033 --> 00:20:16,800
Type of pole being made.
533
00:20:16,800 --> 00:20:18,867
Some ski-pole grips even have
534
00:20:18,867 --> 00:20:20,800
Clips for attaching gloves.
535
00:20:20,800 --> 00:20:22,867
Trekking-pole shafts now roll
536
00:20:22,867 --> 00:20:25,133
Down the production line.
537
00:20:25,133 --> 00:20:27,100
An automated arm slides plastic
538
00:20:27,100 --> 00:20:29,100
Sleeves with carbide points onto
539
00:20:29,100 --> 00:20:33,933
The lower shaft section.
540
00:20:33,933 --> 00:20:35,633
A spinning tool drives part of
541
00:20:35,633 --> 00:20:37,300
An expander mechanism into the
542
00:20:37,300 --> 00:20:40,500
Trekking pole's middle shaft.
543
00:20:40,500 --> 00:20:41,867
This expander will allow the
544
00:20:41,867 --> 00:20:43,033
Pole to be lengthened or
545
00:20:43,033 --> 00:20:44,200
Shortened to the user's
546
00:20:44,200 --> 00:20:46,000
Preference.
547
00:20:46,167 --> 00:20:48,067
Machinery then inserts the other
548
00:20:48,067 --> 00:20:49,867
Part of the expander mechanism
549
00:20:49,867 --> 00:20:53,133
Into the lower shaft.
550
00:20:53,133 --> 00:20:54,900
Finally, a worker assembles the
551
00:20:54,900 --> 00:20:56,567
Parts, sliding one section of
552
00:20:56,567 --> 00:20:58,233
The expander mechanism on the
553
00:20:58,233 --> 00:21:03,067
Other.
554
00:21:03,067 --> 00:21:06,533
Finally, she sharpens the tips.
555
00:21:06,533 --> 00:21:08,233
And these poles are now ready
556
00:21:08,233 --> 00:21:08,900
For action.
