Narrator: today
On "How it's made" --
4
00:00:26,000 --> 00:00:28,000
Rubber balls.
5
00:00:32,172 --> 00:00:34,034
Motion chairs.
6
00:00:38,137 --> 00:00:39,965
Montreal smoked meat.
7
00:00:44,034 --> 00:00:46,000
And motorized scooters.
8
00:00:53,172 --> 00:00:56,896
A lot happens when an inflated
Rubber ball hits the ground.
9
00:00:56,896 --> 00:00:59,241
The rubber compresses
And quickly snaps
10
00:00:59,241 --> 00:01:01,275
Back to its round shape.
11
00:01:01,275 --> 00:01:04,655
That snapping back
Makes the ball bounce.
12
00:01:04,655 --> 00:01:07,172
In addition, the air
Inside the ball acts
13
00:01:07,172 --> 00:01:10,896
As a tightly coiled spring
Increasing the rebound.
14
00:01:14,241 --> 00:01:17,068
When an inflated rubber ball
Falls to the ground,
15
00:01:17,068 --> 00:01:18,310
It bounces back,
16
00:01:18,310 --> 00:01:20,827
And players catch it
On the rebound.
17
00:01:20,827 --> 00:01:23,689
This type of ball is
At the heart of many games,
18
00:01:23,689 --> 00:01:27,551
From basketball
To soccer to volleyball.
19
00:01:27,551 --> 00:01:31,344
At the core is an inflated
Rubber bladder.
20
00:01:31,344 --> 00:01:34,517
Making it starts with a sheet
Of natural rubber.
21
00:01:34,517 --> 00:01:39,068
The factory worker folds it
In a specific configuration.
22
00:01:39,068 --> 00:01:42,827
He places a die on top
And activates a press
23
00:01:42,827 --> 00:01:46,448
To force it through the layers,
Which cuts out the shape.
24
00:01:46,448 --> 00:01:50,310
He now has the bladder
Of a sports ball.
25
00:01:50,310 --> 00:01:53,172
He brushes an adhesive
Around the hole in the bladder
26
00:01:53,172 --> 00:01:55,689
And inserts a plug.
27
00:02:00,241 --> 00:02:02,758
Another worker inflates
The rubber bladder
28
00:02:02,758 --> 00:02:05,793
As she places it
In a spherical chamber.
29
00:02:05,793 --> 00:02:08,551
It heats and cures
The rubber for 5 minutes
30
00:02:08,551 --> 00:02:12,275
At a temperature of
284 degrees fahrenheit.
31
00:02:12,275 --> 00:02:15,241
The rubber bladder spins
On a revolving cylinder,
32
00:02:15,241 --> 00:02:18,241
Causing it to take up
Nylon threads.
33
00:02:18,241 --> 00:02:21,137
The threads twist around
The bladder and form a layer
34
00:02:21,137 --> 00:02:25,137
That both strengthens it
And keeps it round.
35
00:02:25,137 --> 00:02:27,931
The material that will form
The exterior of the ball
36
00:02:27,931 --> 00:02:31,551
Is made using colored synthetic
Rubber, natural rubber,
37
00:02:31,551 --> 00:02:34,448
Magnesium carbonate,
And mineral oil.
38
00:02:34,448 --> 00:02:38,206
Once it cures, a worker
Rolls it into thick sheets
39
00:02:38,206 --> 00:02:40,793
And slices it
To a specific width.
40
00:02:40,793 --> 00:02:43,448
He folds it several times.
41
00:02:43,448 --> 00:02:47,413
This blue rubber will be used
For volleyballs.
42
00:02:47,413 --> 00:02:51,206
The folded rubber now travels
Between a series of rollers.
43
00:02:51,206 --> 00:02:54,137
They flatten it and press
It extremely thin,
44
00:02:54,137 --> 00:02:57,172
And it becomes both
Lightweight and formable.
45
00:02:59,344 --> 00:03:04,310
An automated blade slices
The rubber into shorter pieces.
46
00:03:04,310 --> 00:03:06,517
A metal pattern cutter
Will now be used
47
00:03:06,517 --> 00:03:08,517
To cut the rubber into strips,
48
00:03:08,517 --> 00:03:12,655
Which will fit together
To form the outside of the ball.
49
00:03:12,655 --> 00:03:15,862
These particular strips
Are for a basketball.
50
00:03:15,862 --> 00:03:20,310
The worker places the pattern
On several pieces of rubber.
51
00:03:20,310 --> 00:03:23,931
A press forces the sharp-edged
Pattern through the rubber
52
00:03:23,931 --> 00:03:26,068
To cut out fish-shaped strips
53
00:03:26,068 --> 00:03:28,896
That are designed to fit
Around the round bladder.
54
00:03:32,482 --> 00:03:37,275
She lines the two halves of a
Bonding shaper with the strips.
55
00:03:42,344 --> 00:03:46,103
She inserts the bladder
And re-inflates it.
56
00:03:49,275 --> 00:03:52,758
She closes the bonding
Chamber and activates it.
57
00:03:52,758 --> 00:03:55,689
Inside, heat and pressure
Cause the strips
58
00:03:55,689 --> 00:03:59,206
To stick to the bladder.
59
00:03:59,206 --> 00:04:02,758
To make a medicine ball,
Which is used for exercising,
60
00:04:02,758 --> 00:04:06,310
A different pattern cutter
Is used.
61
00:04:06,310 --> 00:04:08,620
The forming process is the same,
62
00:04:08,620 --> 00:04:12,206
But this ball has a unique
Visual impact very different
63
00:04:12,206 --> 00:04:14,034
From that of the basketball.
64
00:04:17,862 --> 00:04:19,724
Back at the basketball station,
65
00:04:19,724 --> 00:04:24,586
A worker applies the brand name
To the outer skin in two places.
66
00:04:24,586 --> 00:04:28,379
Glue helps the decals
Stick to the rubber.
67
00:04:28,379 --> 00:04:32,034
This mold will now transfer
A pattern onto the rubber ball
68
00:04:32,034 --> 00:04:35,482
While also baking
The lettering into it.
69
00:04:35,482 --> 00:04:39,344
Another worker places the ball
In the mold and pumps more air
70
00:04:39,344 --> 00:04:41,241
Into the bladder.
71
00:04:41,241 --> 00:04:43,034
He closes the lid.
72
00:04:43,034 --> 00:04:44,896
The mold applies heat
And pressure
73
00:04:44,896 --> 00:04:49,275
To emboss the pattern
Onto the rubber.
74
00:04:49,275 --> 00:04:52,034
The lettering has
Penetrated the rubber,
75
00:04:52,034 --> 00:04:55,517
And the worker peels
Off the decal plastic.
76
00:04:55,517 --> 00:04:58,551
Another worker replenishes
The air that's been lost
77
00:04:58,551 --> 00:05:02,206
To make the ball
Completely full and round.
78
00:05:02,206 --> 00:05:05,620
The ball is now ready
To receive its stripes.
79
00:05:05,620 --> 00:05:08,103
The worker paints black rubber
Into grooves
80
00:05:08,103 --> 00:05:10,689
That were formed
During embossing.
81
00:05:10,689 --> 00:05:15,172
This rubber quickly cures
To become part of the ball.
82
00:05:15,172 --> 00:05:18,620
Another worker inserts
A fill valve into the hole.
83
00:05:18,620 --> 00:05:22,551
Then, mechanical fists
Squeeze the ball to deflate it.
84
00:05:22,551 --> 00:05:24,931
This prepares it for packaging.
85
00:05:24,931 --> 00:05:28,137
With the valve inside,
It can be easily re-inflated
86
00:05:28,137 --> 00:05:31,517
By the customer.
87
00:05:31,517 --> 00:05:35,275
A worker wraps it in plastic
And ships it to the retailer.
88
00:05:37,413 --> 00:05:39,896
Making this rubber basketball
Has only taken
89
00:05:39,896 --> 00:05:41,344
A couple of hours,
90
00:05:41,344 --> 00:05:43,758
But it should be able
To take a lot of knocks
91
00:05:43,758 --> 00:05:45,586
And bounce right back.
92
00:05:55,068 --> 00:05:57,000
Narrator:
Having a desk job
93
00:05:57,000 --> 00:05:59,344
Doesn't mean
One has to sit still.
94
00:05:59,344 --> 00:06:02,620
With a motion chair, the office
Worker can keep moving
95
00:06:02,620 --> 00:06:04,724
While staying seated.
96
00:06:04,724 --> 00:06:08,172
The support structure is
Engineered for flexibility,
97
00:06:08,172 --> 00:06:12,241
So while sitting, a person
Can bounce, tilt, and sway.
98
00:06:16,310 --> 00:06:19,689
Motion chairs redefine
The act of sitting.
99
00:06:19,689 --> 00:06:21,206
The stem is springy,
100
00:06:21,206 --> 00:06:23,724
And the connection
To the seat is elastic.
101
00:06:23,724 --> 00:06:28,241
This allows the office worker
To be active while sitting.
102
00:06:28,241 --> 00:06:32,103
Making a motion chair starts
With glass-reinforced plastic,
103
00:06:32,103 --> 00:06:35,206
Which is a strong
And lightweight material.
104
00:06:35,206 --> 00:06:39,000
These granules will be used
To make the core of the seat.
105
00:06:39,000 --> 00:06:44,000
A robot inserts a steel fastener
In the center of the seat mold.
106
00:06:44,000 --> 00:06:47,241
The mold closes, and the machine
Melts the plastic
107
00:06:47,241 --> 00:06:49,827
And injects it into the mold.
108
00:06:49,827 --> 00:06:53,379
The plastic quickly solidifies
Around the steel fastener,
109
00:06:53,379 --> 00:06:57,034
And it becomes part
Of the seat core.
110
00:06:57,034 --> 00:06:59,241
A robot with suctioning grippers
111
00:06:59,241 --> 00:07:04,137
Pulls the convex-shaped
Seat core out.
112
00:07:04,137 --> 00:07:06,000
A worker assembles
A height-adjustment
113
00:07:06,000 --> 00:07:09,379
Lever in the hole beside
The one for the seat stem.
114
00:07:12,413 --> 00:07:15,551
A molded plastic top
Completes the seat core.
115
00:07:19,137 --> 00:07:22,241
He anchors it to the core
With numerous screws,
116
00:07:22,241 --> 00:07:28,137
So even with heavy use, the top
Should stay firmly in place.
117
00:07:28,137 --> 00:07:31,068
He visually inspects
The seat core and confirms
118
00:07:31,068 --> 00:07:33,586
That it looks solid.
119
00:07:36,034 --> 00:07:40,068
Cushioning foam and fabric
Complete the seat.
120
00:07:40,068 --> 00:07:43,310
A worker assembles roller
Mechanisms that will facilitate
121
00:07:43,310 --> 00:07:47,068
The vertical movements
Of the chair's stem.
122
00:07:47,068 --> 00:07:51,206
Using a special assembly tool,
She presses the plastic roller
123
00:07:51,206 --> 00:07:55,068
And two end brackets
On a metal cylinder.
124
00:07:55,068 --> 00:07:58,379
She then applies an index
To an aluminum support column
125
00:07:58,379 --> 00:07:59,655
That serves as a guide
126
00:07:59,655 --> 00:08:02,758
For setting the tension
Of an outer spring.
127
00:08:02,758 --> 00:08:05,517
She inserts the roller
Mechanisms in slots
128
00:08:05,517 --> 00:08:07,758
At the other end of the column.
129
00:08:07,758 --> 00:08:10,965
Strips of fabric tape
Keep the rollers in place.
130
00:08:15,137 --> 00:08:18,689
An air cylinder presses
The outer sleeve onto the column
131
00:08:18,689 --> 00:08:22,448
So that it sits above
The tension index.
132
00:08:22,448 --> 00:08:24,862
A screw between
The inner and outer cylinders
133
00:08:24,862 --> 00:08:28,103
Keeps them in position.
134
00:08:28,103 --> 00:08:30,241
Next up is a compression part
135
00:08:30,241 --> 00:08:33,068
For setting the position
Of the outer seat spring.
136
00:08:35,482 --> 00:08:38,758
A worker slides a metal ring
Between the compression part
137
00:08:38,758 --> 00:08:40,758
And the support column.
138
00:08:40,758 --> 00:08:44,827
He inserts a gas spring into
The double-walled seat stem.
139
00:08:47,103 --> 00:08:50,172
He now slides the outer
Spring onto the assembly.
140
00:08:53,034 --> 00:08:56,655
He installs a plastic casing
Over the gas spring.
141
00:08:56,655 --> 00:09:01,241
Then he puts the seat stem
Inside a press chamber.
142
00:09:01,241 --> 00:09:04,344
He adds a top collar
To the center of the gas spring
143
00:09:04,344 --> 00:09:06,103
As well as a snap ring.
144
00:09:09,310 --> 00:09:13,241
He activates the press, and
It squeezes everything together.
145
00:09:16,034 --> 00:09:19,000
Next is a stand with
Flexible rubber parts
146
00:09:19,000 --> 00:09:24,068
That will make lateral
Movement possible while sitting.
147
00:09:24,068 --> 00:09:28,275
The worker attaches the flexible
Stand to a circular base.
148
00:09:28,275 --> 00:09:31,413
He confirms that holes
For rolling casters or gliders
149
00:09:31,413 --> 00:09:33,965
In the base are
The correct dimension.
150
00:09:36,103 --> 00:09:38,724
He screws a dial
For setting lateral movement
151
00:09:38,724 --> 00:09:41,482
Onto the protruding fastener.
152
00:09:41,482 --> 00:09:46,068
He secures it with a nut
And tightens it.
153
00:09:46,068 --> 00:09:48,448
He covers the nut
With a rubber cap.
154
00:09:50,827 --> 00:09:55,000
A tester will now evaluate
The motion chair's performance.
155
00:09:55,000 --> 00:09:58,103
He attaches the stem
To the base,
156
00:09:58,103 --> 00:10:01,172
And he fastens the seat
To the protruding rod.
157
00:10:03,275 --> 00:10:07,965
He sits down and bounces around
To test the range of movement.
158
00:10:07,965 --> 00:10:10,827
These tests are done
Intermittently to confirm
159
00:10:10,827 --> 00:10:15,034
That the the product
Consistently meets requirements.
160
00:10:15,034 --> 00:10:18,000
This motion chair is now ready
For shipping.
161
00:10:20,068 --> 00:10:22,862
The packer plugs a hole
In the base ring.
162
00:10:22,862 --> 00:10:25,896
This hole is for attaching
An optional backrest.
163
00:10:28,103 --> 00:10:30,758
He applies a sticker
With the product name.
164
00:10:33,068 --> 00:10:34,931
All of the parts
Of the motion chair
165
00:10:34,931 --> 00:10:39,413
Can be easily assembled
On location.
166
00:10:39,413 --> 00:10:43,034
Designed to discourage rigid
Sitting and encourage movement
167
00:10:43,034 --> 00:10:44,758
In any direction,
168
00:10:44,758 --> 00:10:46,793
It will compel
The person using it
169
00:10:46,793 --> 00:10:49,172
To use his or her core muscles
170
00:10:49,172 --> 00:10:52,172
And be less sedentary
On the job.
171
00:10:52,172 --> 00:10:55,034
With the motion chair,
It just may be possible
172
00:10:55,034 --> 00:10:57,241
To get fit while you sit.
173
00:11:05,758 --> 00:11:07,310
Narrator:
For at least a century,
174
00:11:07,310 --> 00:11:09,034
Montreal's jewish delis
175
00:11:09,034 --> 00:11:11,758
Have been serving
Smoked meat on rye.
176
00:11:11,758 --> 00:11:14,413
The exact origins of this
Particular deli meat
177
00:11:14,413 --> 00:11:17,896
Are a matter of debate with
Many claims to its invention.
178
00:11:17,896 --> 00:11:20,517
The juicy details
Have been lost to time,
179
00:11:20,517 --> 00:11:22,103
But montreal smoked meat
180
00:11:22,103 --> 00:11:24,758
Continues to have
An enduring appeal.
181
00:11:27,344 --> 00:11:30,172
A cross between corn beef
And pastrami,
182
00:11:30,172 --> 00:11:31,862
Montreal smoked meat
183
00:11:31,862 --> 00:11:34,827
Has attracted a foodie
Following around the world.
184
00:11:37,379 --> 00:11:40,379
Montreal smoked meat
Starts with brisket,
185
00:11:40,379 --> 00:11:43,379
Which is a cut from
The cow's upper chest.
186
00:11:43,379 --> 00:11:46,275
A worker thaws
The previously frozen briskets
187
00:11:46,275 --> 00:11:50,310
In a refrigerator for 10 hours.
188
00:11:50,310 --> 00:11:52,965
A team slices off
The biggest chunks of fat
189
00:11:52,965 --> 00:11:56,448
Using round, air-powered blades.
190
00:11:56,448 --> 00:11:59,172
The excess fat will be shipped
To another factory
191
00:11:59,172 --> 00:12:01,379
And used to make soap.
192
00:12:01,379 --> 00:12:03,586
The workers use a sharp
Butcher's knife
193
00:12:03,586 --> 00:12:05,620
To remove smaller pieces of fat,
194
00:12:05,620 --> 00:12:08,551
Leaving just enough for flavor.
195
00:12:08,551 --> 00:12:11,275
Next, they prepare the brine.
196
00:12:11,275 --> 00:12:14,379
Along with salt and sugar,
There's a secret recipe
197
00:12:14,379 --> 00:12:16,655
Of spices that
Includes peppers,
198
00:12:16,655 --> 00:12:20,448
Mustard seed,
Allspice, and cinnamon.
199
00:12:20,448 --> 00:12:23,068
The operator combines
The salt and sugar
200
00:12:23,068 --> 00:12:26,517
With ice-cold water
In a high-speed mixer.
201
00:12:26,517 --> 00:12:28,827
The spices have been
Premixed in water
202
00:12:28,827 --> 00:12:32,413
To produce a spice concentrate.
203
00:12:32,413 --> 00:12:34,758
The next worker loads
The trimmed briskets
204
00:12:34,758 --> 00:12:37,379
Onto a conveyor.
205
00:12:37,379 --> 00:12:40,896
It takes the briskets under
An array of long needles
206
00:12:40,896 --> 00:12:46,172
That inject the brine
Into the meat repeatedly.
207
00:12:46,172 --> 00:12:50,379
Laced with brine, the briskets
Then fall into a bin.
208
00:12:50,379 --> 00:12:54,689
A worker transfers the juicy
Briskets into a vacuum tumbler.
209
00:12:54,689 --> 00:12:56,344
It pulls air from the chamber,
210
00:12:56,344 --> 00:12:59,655
Causing the briskets
To absorb more brine.
211
00:12:59,655 --> 00:13:02,620
The tumbler tosses
The briskets for 10 hours,
212
00:13:02,620 --> 00:13:04,827
Massaging the brine
Into the meat.
213
00:13:04,827 --> 00:13:08,000
A layer of protein also
Forms on the surface.
214
00:13:08,000 --> 00:13:11,448
This holds the brine in place.
215
00:13:11,448 --> 00:13:16,103
In the meantime, a worker mixes
The ingredients for the dry rub.
216
00:13:16,103 --> 00:13:18,000
It's comprised of the same
Spices
217
00:13:18,000 --> 00:13:19,758
That were used in the brine
218
00:13:19,758 --> 00:13:22,000
Along with clumps
Of fresh garlic.
219
00:13:25,448 --> 00:13:28,000
After the briskets have been
Well marinated,
220
00:13:28,000 --> 00:13:30,551
The operator adds the dry rub.
221
00:13:30,551 --> 00:13:33,724
He turns on the tumbler
For another half hour.
222
00:13:33,724 --> 00:13:38,482
The dry rub mixture coats
The surface of the meat.
223
00:13:38,482 --> 00:13:40,172
This system is an alternative
224
00:13:40,172 --> 00:13:43,275
To rubbing the spices
Onto the briskets by hand.
225
00:13:43,275 --> 00:13:45,689
It's faster and very efficient.
226
00:13:47,758 --> 00:13:49,689
Coated with smoked meat spices
227
00:13:49,689 --> 00:13:52,000
And injected
With flavorful brine,
228
00:13:52,000 --> 00:13:54,344
The briskets are now
Ready for roasting.
229
00:13:58,448 --> 00:14:04,517
An employee rolls racks of the
Spicy briskets into a huge oven.
230
00:14:04,517 --> 00:14:08,206
The briskets steam-roast
At 210 degrees fahrenheit
231
00:14:08,206 --> 00:14:11,344
For 8 to 10 hours,
232
00:14:11,344 --> 00:14:14,275
But the workers don't
Actually smoke the briskets.
233
00:14:14,275 --> 00:14:16,413
It's the spices and brine
That give them
234
00:14:16,413 --> 00:14:20,413
That montreal
Smoked meat flavor.
235
00:14:20,413 --> 00:14:22,586
After the briskets
Have been chilled,
236
00:14:22,586 --> 00:14:25,137
Workers transfer them
To plastic bags
237
00:14:25,137 --> 00:14:28,000
And place them on a conveyor.
238
00:14:28,000 --> 00:14:32,137
Moving forward, a vacuum-sealing
Head drops down to shrink-wrap
239
00:14:32,137 --> 00:14:34,344
The plastic to the meat.
240
00:14:34,344 --> 00:14:37,620
The vacuum seal and the
Smoked meat spices combined
241
00:14:37,620 --> 00:14:40,379
Give the meat a long shelf life.
242
00:14:40,379 --> 00:14:45,103
Refrigerated, it will stay fresh
For up to 45 days.
243
00:14:45,103 --> 00:14:48,379
This plant ships the entire
Brisket to restaurants.
244
00:14:48,379 --> 00:14:51,137
At the restaurant,
They will re-steam and slice
245
00:14:51,137 --> 00:14:53,413
The brisket before serving.
246
00:14:53,413 --> 00:14:55,793
Next, the smoked meat
Is pre-sliced
247
00:14:55,793 --> 00:14:57,689
To sell in supermarkets.
248
00:14:57,689 --> 00:15:03,482
An automatic meat slicer carves
It into thin pieces in seconds.
249
00:15:03,482 --> 00:15:06,275
A worker retrieves
The sliced smoked meat
250
00:15:06,275 --> 00:15:09,448
And sets it on a tray.
251
00:15:09,448 --> 00:15:11,448
Transferred to a weigh station,
252
00:15:11,448 --> 00:15:16,620
Workers divide the slices
Into 6-ounce portions.
253
00:15:16,620 --> 00:15:20,344
Then they roll up
The smoked meat slices.
254
00:15:20,344 --> 00:15:26,310
A worker places the rolled meat
Into plastic pouches on a rack.
255
00:15:26,310 --> 00:15:27,896
The racks move forward,
256
00:15:27,896 --> 00:15:30,586
And a vacuum sealer
Applies a top film,
257
00:15:30,586 --> 00:15:35,413
Creating little packets
Of sliced smoked meat.
258
00:15:35,413 --> 00:15:38,482
After a quick bake
To pasteurize the meat,
259
00:15:38,482 --> 00:15:42,413
He puts six packets into
Compartments on a conveyor.
260
00:15:42,413 --> 00:15:47,310
A pusher moves the six packets
Of smoked meat into an open box.
261
00:15:47,310 --> 00:15:50,620
The system seals the ends
Of the boxes.
262
00:15:50,620 --> 00:15:55,206
Workers weigh the box
Of smoked meat slices.
263
00:15:55,206 --> 00:15:57,034
It has taken about 30 hours
264
00:15:57,034 --> 00:16:00,724
To produce this batch
Of montreal smoked meat.
265
00:16:00,724 --> 00:16:03,827
It's time to slice it thin
And pile it thick
266
00:16:03,827 --> 00:16:07,068
Between slabs
Of mustard-slathered rye.
267
00:16:07,068 --> 00:16:10,551
Now, that's a deli lunch,
Montreal-style.
268
00:16:21,137 --> 00:16:23,517
Narrator: a motorized scooter
Is a souped-up version
269
00:16:23,517 --> 00:16:25,275
Of an ordinary scooter.
270
00:16:25,275 --> 00:16:27,965
Instead of propelling the wheels
By pushing off the ground
271
00:16:27,965 --> 00:16:31,241
With one leg,
An engine does most of the work.
272
00:16:31,241 --> 00:16:33,862
Some motorized scooters
Are kids' toys,
273
00:16:33,862 --> 00:16:36,000
But others are sturdy vehicles
274
00:16:36,000 --> 00:16:39,413
Suitable for commuting,
Utility, and recreation.
275
00:16:41,586 --> 00:16:43,103
This motorized scooter
276
00:16:43,103 --> 00:16:46,103
Has wheels large enough
And tires wide enough
277
00:16:46,103 --> 00:16:51,034
To drive on any surface,
Even off road.
278
00:16:51,034 --> 00:16:53,655
The manufacturer contracts
This factory
279
00:16:53,655 --> 00:16:55,965
To make the frame components.
280
00:16:55,965 --> 00:16:59,793
Machines cut hollow steel tubes
To the required length.
281
00:16:59,793 --> 00:17:03,275
Then workers program
An automated bending machine
282
00:17:03,275 --> 00:17:06,068
To bend each one
To the required shape.
283
00:17:11,000 --> 00:17:14,137
They make five tubular
Frame parts per scooter,
284
00:17:14,137 --> 00:17:16,551
Strictly following the
Technical drawing supplied
285
00:17:16,551 --> 00:17:20,413
By the manufacturer.
286
00:17:20,413 --> 00:17:23,172
The scooter company subcontracts
The frame assembly
287
00:17:23,172 --> 00:17:25,379
To another factory.
288
00:17:25,379 --> 00:17:28,586
There, a welder mounts
The components on a jig,
289
00:17:28,586 --> 00:17:33,586
Which positions them correctly
While he welds them together.
290
00:17:33,586 --> 00:17:37,586
The non-tubular, flat-frame
Parts are prepared in house,
291
00:17:37,586 --> 00:17:40,965
Cut from sheet steel by
A computer-guided laser cutter.
292
00:17:43,413 --> 00:17:46,000
These flat crossbars
Support the footboard
293
00:17:46,000 --> 00:17:49,379
On which the rider stands.
294
00:17:49,379 --> 00:17:51,931
This flat plate
Supports the battery,
295
00:17:51,931 --> 00:17:56,310
And these arms support
The rear wheel and motor.
296
00:17:56,310 --> 00:17:59,310
After applying a coat
Of anticorrosion paint,
297
00:17:59,310 --> 00:18:01,586
Workers install
The side reflectors
298
00:18:01,586 --> 00:18:04,413
And the knob
That secures the battery.
299
00:18:04,413 --> 00:18:08,965
The paint is baked on
For maximum durability.
300
00:18:08,965 --> 00:18:12,344
The scooter manufacturer
Subcontracts the wheel rims
301
00:18:12,344 --> 00:18:13,689
To another factory
302
00:18:13,689 --> 00:18:17,310
That specializes in
High-precision metal spinning.
303
00:18:17,310 --> 00:18:19,689
A worker there mounts
An aluminum disk
304
00:18:19,689 --> 00:18:22,000
Onto a computer-guided lathe,
305
00:18:22,000 --> 00:18:26,310
Positioning it right next
To a rim-shaped steel mold.
306
00:18:26,310 --> 00:18:29,655
Two rollers push and stretch
The disk over the mold,
307
00:18:29,655 --> 00:18:32,103
Forming the aluminum
To the rim's shape.
308
00:18:34,758 --> 00:18:38,379
Another worker mounts the rim
On a manual-spinning lathe
309
00:18:38,379 --> 00:18:40,517
To finish the shaping.
310
00:18:40,517 --> 00:18:45,724
First, with a cutting knife,
He trims the edge.
311
00:18:45,724 --> 00:18:48,103
After lubricating
The edge with soap,
312
00:18:48,103 --> 00:18:52,000
He uses a forming bar
To turn it inward to form a lip.
313
00:18:54,689 --> 00:18:56,448
Then, with the forming roller,
314
00:18:56,448 --> 00:18:59,620
He stretches the lip
To shape a flange.
315
00:19:07,689 --> 00:19:10,827
Back at the scooter factory,
A worker begins installing
316
00:19:10,827 --> 00:19:13,448
The vehicle's silent
Electric motor.
317
00:19:13,448 --> 00:19:16,137
Its cable will plug into
The electronic module
318
00:19:16,137 --> 00:19:20,551
That runs the motor,
Accelerator, and battery.
319
00:19:20,551 --> 00:19:23,172
The motor is actually located
Inside the hub
320
00:19:23,172 --> 00:19:24,758
Of the rear wheel.
321
00:19:24,758 --> 00:19:28,448
This mounting ring
Holds it in place.
322
00:19:28,448 --> 00:19:31,517
He installs a brake disc
On top of the motor
323
00:19:31,517 --> 00:19:33,517
And another on the front wheel.
324
00:19:33,517 --> 00:19:36,862
A mechanical cable connects
Each handlebar brake lever
325
00:19:36,862 --> 00:19:38,275
To the brake calipers.
326
00:19:38,275 --> 00:19:41,931
When the driver pulls the
Levers, the brake calipers clamp
327
00:19:41,931 --> 00:19:45,620
The discs to the wheels,
Stopping rotation.
328
00:19:45,620 --> 00:19:47,896
Now the final assembly --
329
00:19:47,896 --> 00:19:52,103
Workers bolt the rear wheel
To the frame's support arms.
330
00:19:52,103 --> 00:19:54,241
They insert
The height-adjustable fork,
331
00:19:54,241 --> 00:19:57,551
Made of steel and aluminum,
Into the steering column.
332
00:19:57,551 --> 00:20:00,206
Next, the worker installs
The handlebars,
333
00:20:00,206 --> 00:20:02,827
Which have a thumb-operated
Accelerator throttle,
334
00:20:02,827 --> 00:20:05,689
An lcd monitor
And two hand brakes,
335
00:20:05,689 --> 00:20:08,655
Each with a mechanical
Cable for the calipers.
336
00:20:08,655 --> 00:20:11,896
Each hand brake
Also has one electrical cable.
337
00:20:11,896 --> 00:20:13,310
He connects the throttle line
338
00:20:13,310 --> 00:20:15,965
And the electrical cables
To the monitor.
339
00:20:15,965 --> 00:20:19,206
Then he connects the monitor
To the controller.
340
00:20:19,206 --> 00:20:20,724
When the rider brakes,
341
00:20:20,724 --> 00:20:23,482
The controller
Also cuts power to the motor,
342
00:20:23,482 --> 00:20:26,965
Which allows the scooter's
48-volt lithium ion battery
343
00:20:26,965 --> 00:20:30,379
To regenerate.
344
00:20:30,379 --> 00:20:32,310
This screw knob holds
The battery
345
00:20:32,310 --> 00:20:35,724
Securely against
The battery support plate.
346
00:20:35,724 --> 00:20:38,068
He connects the battery
To the controller,
347
00:20:38,068 --> 00:20:41,172
Then the mechanical cable
From one hand-brake lever
348
00:20:41,172 --> 00:20:42,862
To the front brake calipers
349
00:20:42,862 --> 00:20:46,172
And from the other hand brake
Lever to the rear calipers.
350
00:20:48,448 --> 00:20:50,689
Charging the battery
Takes four hours
351
00:20:50,689 --> 00:20:53,275
When plugged in
To a regular household outlet,
352
00:20:53,275 --> 00:20:57,620
And a full charge
Lasts 31 to 37 miles.
353
00:20:57,620 --> 00:21:00,758
The scooter can climb
An 11% incline
354
00:21:00,758 --> 00:21:04,482
And reach a top speed
Of 20 miles per hour.
