Captions paid for by
Discovery communications
3
00:00:52,827 --> 00:00:56,103
Narrator: truck drivers spend
A lot of time on the road,
4
00:00:56,103 --> 00:00:59,448
So their sleeper rigs become
A home away from home.
5
00:00:59,448 --> 00:01:02,896
Equipped with a refrigerator,
Tv, and microwave,
6
00:01:02,896 --> 00:01:04,724
A sleeper rig
Is more than a place
7
00:01:04,724 --> 00:01:06,482
To bunk down for the night.
8
00:01:06,482 --> 00:01:08,793
It can also be a trucker's
Living space
9
00:01:08,793 --> 00:01:11,482
When it's time to pull over.
10
00:01:13,000 --> 00:01:15,586
Due to the convenience
Of sleeper rigs,
11
00:01:15,586 --> 00:01:17,827
Truckers don't need
To pull into a hotel
12
00:01:17,827 --> 00:01:19,413
Once they've put in their hours.
13
00:01:19,413 --> 00:01:21,482
Instead, they simply pull over
14
00:01:21,482 --> 00:01:24,793
Since they're hauling their own
Sleeping accommodations.
15
00:01:24,793 --> 00:01:29,241
This factory builds custom rigs
Based on drivers' preferences.
16
00:01:29,241 --> 00:01:32,310
Production starts by installing
The steel frame rails
17
00:01:32,310 --> 00:01:34,620
For the vehicle's frame,
Or chassis.
18
00:01:34,620 --> 00:01:36,655
First, machinists
Place the rails
19
00:01:36,655 --> 00:01:38,344
In an upside down position
20
00:01:38,344 --> 00:01:40,344
And wire it for
Indicator lights
21
00:01:40,344 --> 00:01:42,689
And other electrical components.
22
00:01:42,689 --> 00:01:44,965
They run hoses
For the air brakes
23
00:01:44,965 --> 00:01:48,068
And to deliver fuel
To the engine.
24
00:01:48,068 --> 00:01:52,000
They link the two frame rails
With cross members...
25
00:01:52,000 --> 00:01:56,655
And bolt an engine support rail
To the front of the framework.
26
00:01:57,758 --> 00:02:00,517
A crane moves the chassis
Down the line,
27
00:02:00,517 --> 00:02:03,206
While a second crane carries
Three wheel axles
28
00:02:03,206 --> 00:02:05,241
Over to the first crane.
29
00:02:05,241 --> 00:02:08,172
Technicians guide the axles
Into position
30
00:02:08,172 --> 00:02:11,413
As they're lowered
Onto the frame.
31
00:02:11,413 --> 00:02:15,137
The team bolts the axles
To the chassis.
32
00:02:15,137 --> 00:02:17,862
A rollover crane flips
The chassis
33
00:02:17,862 --> 00:02:21,827
And places it on a pedestal
That will move it down the line.
34
00:02:24,000 --> 00:02:27,000
Next, the fifth wheel hitch
Is installed.
35
00:02:27,000 --> 00:02:30,241
That's used to connect
The truck to the trailer.
36
00:02:33,241 --> 00:02:36,103
The team secures the hitch
With clamping bolts
37
00:02:36,103 --> 00:02:38,827
To ensure
It's securely in place.
38
00:02:40,379 --> 00:02:41,862
The engine and transmission
39
00:02:41,862 --> 00:02:44,344
Are now connected
To the chassis.
40
00:02:48,068 --> 00:02:51,379
The team installs
The diesel fuel tank.
41
00:02:51,379 --> 00:02:53,827
Metal straps are wrapped around
The tank,
42
00:02:53,827 --> 00:02:58,517
And brackets are fastened
To the center of the chassis.
43
00:02:58,517 --> 00:03:00,896
Machinists mount the tires
And wheels
44
00:03:00,896 --> 00:03:03,344
Onto the axles in pairs.
45
00:03:03,344 --> 00:03:06,965
This dual wheel system has
A greater load-carrying capacity
46
00:03:06,965 --> 00:03:09,827
Than a single wheel.
47
00:03:09,827 --> 00:03:12,827
Using a multi-spindled
Torque tool,
48
00:03:12,827 --> 00:03:16,827
A technician tightens
All the lug nuts
49
00:03:16,827 --> 00:03:21,827
And writes identifying
Information on the wheel.
50
00:03:21,827 --> 00:03:25,206
Now it's over
To the industrial robots.
51
00:03:25,206 --> 00:03:28,344
These machines assemble the cab
And the sleeper
52
00:03:28,344 --> 00:03:31,586
And rivet the walls of
The structures to frames.
53
00:03:34,793 --> 00:03:36,862
With speed and precision,
54
00:03:36,862 --> 00:03:40,103
The industrial robots
Install the roof
55
00:03:40,103 --> 00:03:43,620
And pipe sealant
On top of the cab frame.
56
00:03:45,413 --> 00:03:48,724
A crane lowers the roof
Onto the cab
57
00:03:48,724 --> 00:03:51,344
And bolts the structure
Together.
58
00:03:51,344 --> 00:03:54,000
Meanwhile,
Other industrial robots
59
00:03:54,000 --> 00:03:57,000
Paint the cab, sleeper,
And hood.
60
00:03:57,000 --> 00:03:59,758
The color is usually
A custom choice,
61
00:03:59,758 --> 00:04:04,344
As are the size and amenities
Of the sleeper.
62
00:04:04,344 --> 00:04:09,275
A team slides the dashboard
Subassembly into the cab.
63
00:04:09,275 --> 00:04:11,793
They bolt the dashboard
To the cab
64
00:04:11,793 --> 00:04:15,689
And connect the components
To the rest of the truck.
65
00:04:15,689 --> 00:04:18,275
This is an inside look
At the sleeper cab,
66
00:04:18,275 --> 00:04:21,482
Which has been wired
For lights and heat.
67
00:04:23,586 --> 00:04:28,413
Technicians install
The cabinetry.
68
00:04:28,413 --> 00:04:31,068
Other features
Inside the sleeper cab
69
00:04:31,068 --> 00:04:35,068
Include cabinets equipped
With a radio, charger outlets,
70
00:04:35,068 --> 00:04:37,689
Cup holders,
Fold-up bunk beds,
71
00:04:37,689 --> 00:04:40,310
And mini fridge.
72
00:04:40,310 --> 00:04:43,172
Once all interior components
Are installed,
73
00:04:43,172 --> 00:04:46,586
The team connects
The sleeper to the cab.
74
00:04:46,586 --> 00:04:49,551
Then they bolt
The two pieces together.
75
00:04:52,103 --> 00:04:54,931
The cab and sleeper assembly
Is now ready
76
00:04:54,931 --> 00:04:56,965
To be mounted to the chassis.
77
00:04:56,965 --> 00:04:59,689
A crane lowers it into place.
78
00:05:02,413 --> 00:05:05,689
The team secures the hood
To the front rail.
79
00:05:05,689 --> 00:05:08,517
The hood contains a mechanism
That will allow it
80
00:05:08,517 --> 00:05:10,689
To open and close with ease
81
00:05:10,689 --> 00:05:13,068
And lock in an open position.
82
00:05:13,068 --> 00:05:15,137
Next, the assembled truck
83
00:05:15,137 --> 00:05:17,379
Heads to
The wheel alignment station.
84
00:05:17,379 --> 00:05:20,413
There, an inspector monitors
Alignment readouts
85
00:05:20,413 --> 00:05:23,000
From lasers and 3-d cameras.
86
00:05:23,000 --> 00:05:24,586
This information lets them know
87
00:05:24,586 --> 00:05:27,344
The wheel's positioning
On the axle.
88
00:05:27,344 --> 00:05:29,068
Based on the data,
89
00:05:29,068 --> 00:05:32,482
He loosens the bolts that hold
The axles to the wheels
90
00:05:32,482 --> 00:05:34,034
And turns the axle
91
00:05:34,034 --> 00:05:36,586
To make
Any additional adjustments.
92
00:05:39,586 --> 00:05:42,551
Once all the technical
Modifications have been made,
93
00:05:42,551 --> 00:05:46,000
Technicians lock a kingpin
Into the fifth wheel hitch
94
00:05:46,000 --> 00:05:49,586
And turn the wheels to confirm
That everything is secure.
95
00:05:49,586 --> 00:05:53,241
This truck is now ready to hit
The road and get to work.
96
00:06:02,758 --> 00:06:05,068
Narrator: pecans grow on trees
97
00:06:05,068 --> 00:06:07,758
That are native to
South central north america.
98
00:06:07,758 --> 00:06:10,379
In fact, "Pecan" is
An algonquin word
99
00:06:10,379 --> 00:06:13,482
That means "A nut that takes
A stone to crack."
100
00:06:13,482 --> 00:06:18,310
Today, computerized shelling
Machines do that job for you.
101
00:06:20,344 --> 00:06:23,724
Pecans add flavor
And crunch to any recipe.
102
00:06:23,724 --> 00:06:27,310
They can also be a satisfying
Treat on their own.
103
00:06:27,310 --> 00:06:32,068
But manufacturing pecans is an
Entirely different nut to crack.
104
00:06:33,379 --> 00:06:38,172
At harvest time, the husks that
Contain the nuts start to open.
105
00:06:38,172 --> 00:06:39,689
At this orchard,
106
00:06:39,689 --> 00:06:41,551
A machine grabs the tree trunks
107
00:06:41,551 --> 00:06:44,379
And shakes the nuts
To the ground.
108
00:06:51,000 --> 00:06:54,482
Once on the ground,
A sweeper moves the pecans
109
00:06:54,482 --> 00:06:57,413
Away from the trees
And into a row.
110
00:06:57,413 --> 00:07:00,758
It also blows away
Some of the lighter debris.
111
00:07:03,275 --> 00:07:08,344
A harvester with paddle wheels
Collects the pecans.
112
00:07:08,344 --> 00:07:11,965
Once on the harvester,
The pecans ride chain conveyors
113
00:07:11,965 --> 00:07:15,344
As vacuums remove
And discard debris
114
00:07:15,344 --> 00:07:20,965
Then the pecans are transferred
To a cleaning plant.
115
00:07:20,965 --> 00:07:23,862
The pecans are unloaded
Into a pit,
116
00:07:23,862 --> 00:07:28,068
And a conveyor
Takes them inside.
117
00:07:28,068 --> 00:07:32,551
The pecans funnel into a slotted
Drum and tumble around.
118
00:07:32,551 --> 00:07:35,413
The drum sorts
The dehusked pecans
119
00:07:35,413 --> 00:07:38,379
From those that have retained
Their husks.
120
00:07:38,379 --> 00:07:40,241
In this enclosed machine,
121
00:07:40,241 --> 00:07:44,310
Spinning wire brushes
Remove more of the husks.
122
00:07:44,310 --> 00:07:47,275
Blowers release the lighter
Husks into a big bin
123
00:07:47,275 --> 00:07:50,103
To be disposed of later.
124
00:07:50,103 --> 00:07:51,758
After more processing,
125
00:07:51,758 --> 00:07:56,275
Pictures of the nuts
Are taken with cameras.
126
00:07:56,275 --> 00:07:58,620
A computer monitors
The pictures
127
00:07:58,620 --> 00:08:02,620
For any husks
Still attached to the pecans.
128
00:08:02,620 --> 00:08:04,275
If any are identified,
129
00:08:04,275 --> 00:08:08,275
The computer activates
A blower to remove them.
130
00:08:10,448 --> 00:08:13,827
With the husks removed,
Harvesters sort out
131
00:08:13,827 --> 00:08:17,413
Any of the pecans that
Are cracked or split open.
132
00:08:19,827 --> 00:08:24,172
At this point, the pecans
Contains about 12% moisture,
133
00:08:24,172 --> 00:08:28,000
Which is high enough
To cause deterioration.
134
00:08:28,000 --> 00:08:32,034
So harvesters leave the pecans
To dry for 24 hours,
135
00:08:32,034 --> 00:08:35,551
To lower their moisture content
To 4%.
136
00:08:35,551 --> 00:08:37,379
Once drying is complete,
137
00:08:37,379 --> 00:08:40,379
The pecans are transferred
To the shelling plant,
138
00:08:40,379 --> 00:08:43,586
Where they are plunged into
A chlorine-and-water bath.
139
00:08:43,586 --> 00:08:46,620
This both cleans them
And rehydrates them.
140
00:08:46,620 --> 00:08:48,413
Without sufficient moisture,
141
00:08:48,413 --> 00:08:51,448
The pecans will break into bits
During cracking,
142
00:08:51,448 --> 00:08:56,517
And the objective is to extract
Intact halves for retail.
143
00:08:56,517 --> 00:08:58,413
The pecans are rinsed in water
144
00:08:58,413 --> 00:09:01,448
At a temperature
Of 180 degrees fahrenheit.
145
00:09:01,448 --> 00:09:04,172
This step
Removes chlorine residue,
146
00:09:04,172 --> 00:09:06,344
Sanitizes the pecans,
147
00:09:06,344 --> 00:09:10,862
And raises the moisture content
To 7.5%.
148
00:09:10,862 --> 00:09:12,655
Now it's time to get cracking
149
00:09:12,655 --> 00:09:16,586
With the completely
Automated process.
150
00:09:16,586 --> 00:09:17,931
Inside the sheller,
151
00:09:17,931 --> 00:09:21,241
Pistons hit each end
Of a nut simultaneously,
152
00:09:21,241 --> 00:09:22,965
Cracking it cleanly.
153
00:09:22,965 --> 00:09:26,931
The deshelled pecans travel
Across a vibrating sifter
154
00:09:26,931 --> 00:09:29,448
That sorts them by size.
155
00:09:29,448 --> 00:09:33,241
Then the pecans fall in front
Of an electronic system,
156
00:09:33,241 --> 00:09:35,448
Which releases a blast of air
157
00:09:35,448 --> 00:09:38,413
That removes any lingering
Shell pieces.
158
00:09:38,413 --> 00:09:40,000
A second sifting system
159
00:09:40,000 --> 00:09:43,344
Removes any additional
Small pecan bits.
160
00:09:43,344 --> 00:09:45,241
These pecans will be processed
161
00:09:45,241 --> 00:09:48,965
Into candy bars
And commercial pastries.
162
00:09:48,965 --> 00:09:52,103
The electronic sorter
Has removed most of the shells,
163
00:09:52,103 --> 00:09:53,758
But not all of them.
164
00:09:53,758 --> 00:09:56,448
Technicians visually scan
The pecans
165
00:09:56,448 --> 00:10:00,724
And pick out
The remaining shells.
166
00:10:00,724 --> 00:10:03,482
The pecans continue along
The conveyor
167
00:10:03,482 --> 00:10:07,896
And fall into cardboard boxes
At the end of the line.
168
00:10:07,896 --> 00:10:10,379
To prepare
A toasted pecan snack food,
169
00:10:10,379 --> 00:10:13,137
Salt and butter are added
To the nuts.
170
00:10:13,137 --> 00:10:16,620
Then the nuts are cooked
And mixed in a roaster.
171
00:10:18,344 --> 00:10:22,068
In packaging, technicians
Pour the pecans
172
00:10:22,068 --> 00:10:23,586
Into measuring jugs,
173
00:10:23,586 --> 00:10:26,620
Then empty them
Into plastic bags.
174
00:10:30,137 --> 00:10:33,172
Hot jaws seal
The tops of the bags
175
00:10:33,172 --> 00:10:38,275
To keep the pecans fresh
And extend their shelf life.
176
00:10:38,275 --> 00:10:42,068
Ready for retail, consumers
Won't have any trouble
177
00:10:42,068 --> 00:10:43,655
Cracking these pecans.
178
00:10:43,655 --> 00:10:46,413
They can go straight
To snacking.
179
00:10:57,965 --> 00:11:00,310
Narrator:
A belt and pulley system
180
00:11:00,310 --> 00:11:02,310
Is a simple type of machine.
181
00:11:02,310 --> 00:11:04,206
Two or more pulleys rotate,
182
00:11:04,206 --> 00:11:06,068
Moving a belt
Wrapped around them,
183
00:11:06,068 --> 00:11:08,758
Transferring
Mechanical power.
184
00:11:08,758 --> 00:11:12,034
Torque, speed, direction,
And other factors
185
00:11:12,034 --> 00:11:13,965
Can be altered by using pulleys
186
00:11:13,965 --> 00:11:17,413
Of varying diameters
And designs.
187
00:11:19,344 --> 00:11:21,206
Split pulleys drive a belt,
188
00:11:21,206 --> 00:11:23,586
While idler pulleys
Apply tension
189
00:11:23,586 --> 00:11:26,448
Or change its direction.
190
00:11:26,448 --> 00:11:28,965
Both are manufactured
From steel coil,
191
00:11:28,965 --> 00:11:30,862
The industrial term for steel
192
00:11:30,862 --> 00:11:34,793
That's delivered
To the factory in a roll.
193
00:11:34,793 --> 00:11:37,379
The width and thickness
Of the steel varies,
194
00:11:37,379 --> 00:11:40,103
Depending on the size
Of the pulley being made
195
00:11:40,103 --> 00:11:42,034
And the load it will carry.
196
00:11:44,000 --> 00:11:48,103
To make split pulleys, the coil
Enters a stamping press,
197
00:11:48,103 --> 00:11:50,310
Which punches out discs.
198
00:11:50,310 --> 00:11:54,310
Each disc, called a blank,
Will become one pulley.
199
00:11:54,310 --> 00:11:58,310
The scrap pieces go back to
The steel mill to be recycled.
200
00:11:58,310 --> 00:12:01,344
Each blank has a hole
In the center.
201
00:12:01,344 --> 00:12:05,275
This particular blank
Has three drain holes.
202
00:12:06,586 --> 00:12:09,724
A magnetic arm picks up
One blank at a time
203
00:12:09,724 --> 00:12:13,448
And loads it into
An automated splitting machine.
204
00:12:15,344 --> 00:12:17,103
As the blank rotates,
205
00:12:17,103 --> 00:12:20,068
A circular knife cuts the border
Around the blank
206
00:12:20,068 --> 00:12:21,586
To a specific depth,
207
00:12:21,586 --> 00:12:23,896
Splitting the edge of the blank.
208
00:12:23,896 --> 00:12:27,896
On the opposite side, another
Tool spreads the split edge,
209
00:12:27,896 --> 00:12:29,241
Forming a groove.
210
00:12:29,241 --> 00:12:31,689
The machine doesn't
Remove any steel.
211
00:12:31,689 --> 00:12:35,344
Rather, it forms the groove
To a specific shape
212
00:12:35,344 --> 00:12:39,241
By redistributing
The existing metal.
213
00:12:39,241 --> 00:12:43,931
A welder places the split pulley
Into a welding machine,
214
00:12:43,931 --> 00:12:48,413
Then inserts a machined
Steel hub in the center hole.
215
00:12:48,413 --> 00:12:52,965
The machine welds the hub to
The pulley in about 20 seconds.
216
00:12:54,172 --> 00:12:57,344
An idler pulley is made
From two halves
217
00:12:57,344 --> 00:13:01,344
Rather than from a single blank
Like the split pulley.
218
00:13:01,344 --> 00:13:05,413
To make each half, the steel
Coil goes through a press
219
00:13:05,413 --> 00:13:08,241
In which a dye
With multiple stations
220
00:13:08,241 --> 00:13:10,827
Stamps the metal
To the required shape,
221
00:13:10,827 --> 00:13:13,103
Then cuts it from the coil.
222
00:13:15,482 --> 00:13:18,379
Separate conveyors
Feed the two stamped halves
223
00:13:18,379 --> 00:13:20,448
To an assembly carousel.
224
00:13:20,448 --> 00:13:22,896
One half
Runs through a small press
225
00:13:22,896 --> 00:13:25,724
Which stamps dimples
On the surface,
226
00:13:25,724 --> 00:13:31,448
Then loads it onto
The carousel's first station.
227
00:13:31,448 --> 00:13:34,862
The carousel then rotates
To the next station,
228
00:13:34,862 --> 00:13:39,724
Which inserts a radial
Ball bearing in the center hole.
229
00:13:39,724 --> 00:13:44,206
The next station places a stamp
Without dimples.
230
00:13:44,206 --> 00:13:46,896
A press squeezes
The parts together
231
00:13:46,896 --> 00:13:51,620
Until the dimples touch
The non-dimpled half.
232
00:13:51,620 --> 00:13:54,827
A magnetic arm transfers
The pulley to a track,
233
00:13:54,827 --> 00:13:56,758
Leading to a projection welder.
234
00:13:56,758 --> 00:14:00,068
The welder applies an electric
Current to the dimples,
235
00:14:00,068 --> 00:14:04,620
Melting the two halves
Together at the contact points.
236
00:14:04,620 --> 00:14:08,034
A robotic arm positions
The pulley on the next station,
237
00:14:08,034 --> 00:14:12,068
Which presses a bore adapter
Into the center of the bearing.
238
00:14:12,068 --> 00:14:15,068
This adapter enables the pulley
To be installed
239
00:14:15,068 --> 00:14:17,137
With a smaller bolt.
240
00:14:17,137 --> 00:14:20,724
The thickness of the bore
Adapter also acts as a spacer
241
00:14:20,724 --> 00:14:25,344
To align the center of
The pulley with the belt path.
242
00:14:25,344 --> 00:14:28,758
Next, the samples are tested
For weld strength.
243
00:14:28,758 --> 00:14:32,068
A hydraulic jaw clamps
One half of the pulley
244
00:14:32,068 --> 00:14:35,172
While another jaw pulls
The other half apart.
245
00:14:35,172 --> 00:14:39,172
The welds must remain intact
To pass the test.
246
00:14:39,172 --> 00:14:43,068
Split pulleys undergo a weld
Strength test on the hub.
247
00:14:43,068 --> 00:14:46,724
A hot chemical bath removes
Traces of lubricating oil
248
00:14:46,724 --> 00:14:49,724
Left by the machining equipment.
249
00:14:49,724 --> 00:14:52,896
A thorough rinse with
An anticorrosion chemical
250
00:14:52,896 --> 00:14:55,000
Prevents the steel from rusting
251
00:14:55,000 --> 00:14:59,000
And preps the surface
For painting.
252
00:14:59,000 --> 00:15:01,103
Once the pulleys are dry,
253
00:15:01,103 --> 00:15:03,862
A technician loads them
Onto the paint line,
254
00:15:03,862 --> 00:15:06,137
Masking the center with a plug.
255
00:15:11,034 --> 00:15:13,689
Inside the automated
Paint tunnel,
256
00:15:13,689 --> 00:15:15,551
Three spray guns fully coat
257
00:15:15,551 --> 00:15:18,655
The top, middle, and bottom
Of the spinning pulley
258
00:15:18,655 --> 00:15:21,241
With a water-based enamel paint.
259
00:15:24,551 --> 00:15:27,344
Then the pulley
Passes through a tunnel oven,
260
00:15:27,344 --> 00:15:30,586
Which heat cures the paint
In about four minutes.
261
00:15:34,413 --> 00:15:37,068
The pulley,
Upon exiting the oven,
262
00:15:37,068 --> 00:15:40,000
Goes directly
Into the shipping box,
263
00:15:40,000 --> 00:15:45,310
And an unpainted pulley
Takes its place on the line.
264
00:15:45,310 --> 00:15:48,724
The factory sends select pulleys
To an outside facility
265
00:15:48,724 --> 00:15:51,896
To be plated with zinc
Rather than painted.
266
00:15:51,896 --> 00:15:54,517
Zinc plating better
Protects the steel
267
00:15:54,517 --> 00:15:57,965
When exposed to
Corrosive environments.
268
00:16:07,965 --> 00:16:10,655
Narrator: looking for
A new pair of glasses?
269
00:16:10,655 --> 00:16:12,448
If so, you might want
To look into
270
00:16:12,448 --> 00:16:16,000
Durable, lightweight,
And flexible acetate frames.
271
00:16:16,000 --> 00:16:18,620
Acetate is
A high-quality plastic
272
00:16:18,620 --> 00:16:20,896
Made from cotton or wood fibers.
273
00:16:20,896 --> 00:16:23,896
It can be produced in
An endless array of colors,
274
00:16:23,896 --> 00:16:26,689
Color combinations,
And finishes.
275
00:16:28,482 --> 00:16:31,620
This eyewear is
Made of cellulose acetate,
276
00:16:31,620 --> 00:16:34,655
A transparent plastic
Made from cotton fibers
277
00:16:34,655 --> 00:16:39,206
Combined with plasticizers
And binders.
278
00:16:39,206 --> 00:16:42,206
The acetate arrives
As a thick sheet.
279
00:16:42,206 --> 00:16:44,275
A computer-guided mill
Cuts a slab
280
00:16:44,275 --> 00:16:48,724
For the front of the frame
And two pieces for the temples.
281
00:16:48,724 --> 00:16:50,965
The cuts are carefully
Calculated
282
00:16:50,965 --> 00:16:52,862
To ensure any color variations
283
00:16:52,862 --> 00:16:57,103
Will be in the same
Location on every frame.
284
00:16:57,103 --> 00:16:59,793
This machine heats
The frame front slab
285
00:16:59,793 --> 00:17:02,620
And applies a mold
To form the bridge bump,
286
00:17:02,620 --> 00:17:06,620
The part of the frame
That bulges out over the nose.
287
00:17:06,620 --> 00:17:10,517
The machine drops the slab
Into cold water.
288
00:17:10,517 --> 00:17:14,379
Once the slab has cooled,
This computer-guided machine
289
00:17:14,379 --> 00:17:17,034
Shapes it into a frame front.
290
00:17:17,034 --> 00:17:18,965
Using 16 different tools
291
00:17:18,965 --> 00:17:21,448
Operating from
Five different angles,
292
00:17:21,448 --> 00:17:23,517
The machine carves out
The eyeholes
293
00:17:23,517 --> 00:17:26,379
And makes grooves in them
To hold the lenses,
294
00:17:26,379 --> 00:17:29,172
Then carves the outer shape.
295
00:17:29,172 --> 00:17:31,793
An artisan refines the shape
296
00:17:31,793 --> 00:17:34,137
And smoothes
The surface by hand,
297
00:17:34,137 --> 00:17:37,689
Using files
And custom-made tools.
298
00:17:37,689 --> 00:17:41,379
Then the acetate parts
Are placed in a tumbler
299
00:17:41,379 --> 00:17:44,758
With hardwood pegs
And polishing compounds.
300
00:17:44,758 --> 00:17:49,689
The acetate is smoothed
And polished by gentle abrasion.
301
00:17:49,689 --> 00:17:53,586
A tiny pocket is carved on
Each side of the frame front
302
00:17:53,586 --> 00:17:55,586
For the hinge.
303
00:17:55,586 --> 00:17:59,862
Next, the machine heats the
Hinge with an electric current
304
00:17:59,862 --> 00:18:02,137
And places it in the pocket.
305
00:18:02,137 --> 00:18:06,620
The heat melts the acetate,
Securely setting the hinge.
306
00:18:08,344 --> 00:18:12,862
The brand logo features
A pyramid comprised of 21 dots.
307
00:18:12,862 --> 00:18:15,413
This computer-guided
Precision drill bores
308
00:18:15,413 --> 00:18:19,206
21 tiny holes
Into the tip of the temple.
309
00:18:19,206 --> 00:18:23,758
A craftsman fills them
With translucent epoxy.
310
00:18:23,758 --> 00:18:25,896
Once the epoxy dries,
311
00:18:25,896 --> 00:18:30,689
The craftsman removes the excess
Epoxy with a fine sanding disc.
312
00:18:30,689 --> 00:18:34,172
This requires applying just
The correct amount of pressure.
313
00:18:34,172 --> 00:18:37,241
Otherwise, the acetate
Can get damaged.
314
00:18:37,241 --> 00:18:40,068
Custom-designed equipment
Tapers each temple
315
00:18:40,068 --> 00:18:41,793
To an ergonomic shape.
316
00:18:41,793 --> 00:18:45,275
The temple is thicker
At the hinge for strength,
317
00:18:45,275 --> 00:18:48,034
Thinner around the back
Of the ear for comfort,
318
00:18:48,034 --> 00:18:51,310
And thickest at the end,
Creating weight at the back
319
00:18:51,310 --> 00:18:55,310
To offset pressure
On the bridge of the nose.
320
00:18:55,310 --> 00:18:57,758
Next, a craftsman
Heats the temple
321
00:18:57,758 --> 00:18:59,931
To soften the acetate.
322
00:18:59,931 --> 00:19:03,448
The temple is loaded into
A wire-shooting machine,
323
00:19:03,448 --> 00:19:07,275
Along with a hinged
Nickel silver wire.
324
00:19:07,275 --> 00:19:10,862
The machine shoots the wire
Through the core of the temple.
325
00:19:10,862 --> 00:19:13,206
The temple is now adjustable
326
00:19:13,206 --> 00:19:17,000
And attachable
To the frame front hinge.
327
00:19:17,000 --> 00:19:20,310
A craftsman
Carefully removes excess acetate
328
00:19:20,310 --> 00:19:22,379
With a razor blade.
329
00:19:25,034 --> 00:19:28,517
Then he smoothes out the acetate
Around the hinge
330
00:19:28,517 --> 00:19:30,413
With a heat press.
331
00:19:30,413 --> 00:19:34,068
Finally, he covers the hinge
With a glue cap.
332
00:19:34,068 --> 00:19:36,068
This will shield it from damage
333
00:19:36,068 --> 00:19:39,241
Throughout the remainder
Of the production process.
334
00:19:43,275 --> 00:19:46,103
A laser engraves the logo,
Model name,
335
00:19:46,103 --> 00:19:50,275
Color, and size information
On the inside of the temple.
336
00:19:50,275 --> 00:19:53,275
Now the glasses are ready
To be assembled.
337
00:19:53,275 --> 00:19:57,758
A craftsman cuts matching angles
On the temples and frame front.
338
00:20:00,172 --> 00:20:02,724
He joins the temple
And frame front hinges
339
00:20:02,724 --> 00:20:04,965
With a nylon-coated screw.
340
00:20:04,965 --> 00:20:07,344
The coating
Tightens the parts together
341
00:20:07,344 --> 00:20:10,793
And helps the temples
Fold and unfold smoothly.
342
00:20:11,931 --> 00:20:14,758
A craftsman hand files
The angles
343
00:20:14,758 --> 00:20:20,137
So there's no gap between
Temples and frame front.
344
00:20:20,137 --> 00:20:22,448
Each frame is hand-polished
345
00:20:22,448 --> 00:20:24,896
With progressively finer
Buffing wheels
346
00:20:24,896 --> 00:20:27,931
And different
Polishing compounds.
347
00:20:29,620 --> 00:20:34,172
Optical frames are shipped out
With temporary plastic lenses,
348
00:20:34,172 --> 00:20:35,931
Which an optician replaces
349
00:20:35,931 --> 00:20:39,137
With the customer's
Prescription lenses.
350
00:20:39,137 --> 00:20:42,517
This mechanical machine cuts
The plastic to the shape
351
00:20:42,517 --> 00:20:46,310
Of the frame's eyeholes,
Following a model lens.
352
00:20:47,965 --> 00:20:51,241
The temporary lenses have
A bevel on their edge,
353
00:20:51,241 --> 00:20:54,206
Which fits into
The lens groove of the frame.
354
00:20:54,206 --> 00:20:56,103
From start to finish,
355
00:20:56,103 --> 00:20:59,896
It takes two weeks to create
A single pair of frames.
356
00:20:59,896 --> 00:21:03,758
The process takes over
70 different production steps,
357
00:21:03,758 --> 00:21:07,000
More than half of which
Are performed manually.
