00:00:22,323 --> 00:00:25,891
Today on "how it's made" --
2
00:00:25,893 --> 00:00:27,893
rubber balls.
3
00:00:32,066 --> 00:00:33,932
motion chairs.
4
00:00:38,039 --> 00:00:39,872
montreal smoked meat.
5
00:00:43,944 --> 00:00:45,911
and motorized scooters.
6
00:00:53,054 --> 00:00:56,755
a lot happens when an inflated
rubber ball hits the ground.
7
00:00:56,757 --> 00:00:59,124
The rubber compresses
and quickly snaps
8
00:00:59,126 --> 00:01:01,160
back to its round shape.
9
00:01:01,162 --> 00:01:04,530
That snapping back
makes the ball bounce.
10
00:01:04,532 --> 00:01:07,032
In addition, the air
inside the ball acts
11
00:01:07,034 --> 00:01:10,803
as a tightly coiled spring
increasing the rebound.
12
00:01:14,108 --> 00:01:16,975
When an inflated rubber ball
falls to the ground,
13
00:01:16,977 --> 00:01:18,210
it bounces back,
14
00:01:18,212 --> 00:01:20,712
and players catch it
on the rebound.
15
00:01:20,714 --> 00:01:23,582
This type of ball is
at the heart of many games,
16
00:01:23,584 --> 00:01:27,453
from basketball
to soccer to volleyball.
17
00:01:27,455 --> 00:01:31,223
At the core is an inflated
rubber bladder.
18
00:01:31,225 --> 00:01:34,393
Making it starts with a sheet
of natural rubber.
19
00:01:34,395 --> 00:01:38,931
The factory worker folds it
in a specific configuration.
20
00:01:38,933 --> 00:01:42,701
He places a die on top
and activates a press
21
00:01:42,703 --> 00:01:46,338
to force it through the layers,
which cuts out the shape.
22
00:01:46,340 --> 00:01:50,209
He now has the bladder
of a sports ball.
23
00:01:50,211 --> 00:01:53,078
He brushes an adhesive
around the hole in the bladder
24
00:01:53,080 --> 00:01:55,614
and inserts a plug.
25
00:02:00,154 --> 00:02:02,654
Another worker inflates
the rubber bladder
26
00:02:02,656 --> 00:02:05,657
as she places it
in a spherical chamber.
27
00:02:05,659 --> 00:02:08,427
It heats and cures
the rubber for 5 minutes
28
00:02:08,429 --> 00:02:12,164
at a temperature of
284 degrees fahrenheit.
29
00:02:12,166 --> 00:02:15,134
The rubber bladder spins
on a revolving cylinder,
30
00:02:15,136 --> 00:02:18,137
causing it to take up
nylon threads.
31
00:02:18,139 --> 00:02:21,039
The threads twist around
the bladder and form a layer
32
00:02:21,041 --> 00:02:25,010
that both strengthens it
and keeps it round.
33
00:02:25,012 --> 00:02:27,813
The material that will form
the exterior of the ball
34
00:02:27,815 --> 00:02:31,450
is made using colored synthetic
rubber, natural rubber,
35
00:02:31,452 --> 00:02:34,353
magnesium carbonate,
and mineral oil.
36
00:02:34,355 --> 00:02:38,090
Once it cures, a worker
rolls it into thick sheets
37
00:02:38,092 --> 00:02:40,692
and slices it
to a specific width.
38
00:02:40,694 --> 00:02:43,328
He folds it several times.
39
00:02:43,330 --> 00:02:47,266
This blue rubber will be used
for volleyballs.
40
00:02:47,268 --> 00:02:51,103
The folded rubber now travels
between a series of rollers.
41
00:02:51,105 --> 00:02:54,039
They flatten it and press
it extremely thin,
42
00:02:54,041 --> 00:02:57,109
and it becomes both
lightweight and formable.
43
00:02:59,246 --> 00:03:04,216
An automated blade slices
the rubber into shorter pieces.
44
00:03:04,218 --> 00:03:06,418
A metal pattern cutter
will now be used
45
00:03:06,420 --> 00:03:08,420
to cut the rubber into strips,
46
00:03:08,422 --> 00:03:12,524
which will fit together
to form the outside of the ball.
47
00:03:12,526 --> 00:03:15,727
These particular strips
are for a basketball.
48
00:03:15,729 --> 00:03:20,165
The worker places the pattern
on several pieces of rubber.
49
00:03:20,167 --> 00:03:23,835
A press forces the sharp-edged
pattern through the rubber
50
00:03:23,837 --> 00:03:25,938
to cut out fish-shaped strips
51
00:03:25,940 --> 00:03:28,807
that are designed to fit
around the round bladder.
52
00:03:32,346 --> 00:03:37,182
She lines the two halves of a
bonding shaper with the strips.
53
00:03:42,256 --> 00:03:46,024
she inserts the bladder
and re-inflates it.
54
00:03:49,163 --> 00:03:52,631
She closes the bonding
chamber and activates it.
55
00:03:52,633 --> 00:03:55,601
Inside, heat and pressure
cause the strips
56
00:03:55,603 --> 00:03:59,071
to stick to the bladder.
57
00:03:59,073 --> 00:04:02,641
To make a medicine ball,
which is used for exercising,
58
00:04:02,643 --> 00:04:06,211
a different pattern cutter
is used.
59
00:04:06,213 --> 00:04:08,513
The forming process is the same,
60
00:04:08,515 --> 00:04:12,117
but this ball has a unique
visual impact very different
61
00:04:12,119 --> 00:04:13,986
from that of the basketball.
62
00:04:17,758 --> 00:04:19,591
Back at the basketball station,
63
00:04:19,593 --> 00:04:24,463
a worker applies the brand name
to the outer skin in two places.
64
00:04:24,465 --> 00:04:28,233
Glue helps the decals
stick to the rubber.
65
00:04:28,235 --> 00:04:31,903
This mold will now transfer
a pattern onto the rubber ball
66
00:04:31,905 --> 00:04:35,374
while also baking
the lettering into it.
67
00:04:35,376 --> 00:04:39,244
Another worker places the ball
in the mold and pumps more air
68
00:04:39,246 --> 00:04:41,146
into the bladder.
69
00:04:41,148 --> 00:04:42,948
He closes the lid.
70
00:04:42,950 --> 00:04:44,783
The mold applies heat
and pressure
71
00:04:44,785 --> 00:04:49,187
to emboss the pattern
onto the rubber.
72
00:04:49,189 --> 00:04:51,890
The lettering has
penetrated the rubber,
73
00:04:51,892 --> 00:04:55,394
and the worker peels
off the decal plastic.
74
00:04:55,396 --> 00:04:58,430
Another worker replenishes
the air that's been lost
75
00:04:58,432 --> 00:05:02,100
to make the ball
completely full and round.
76
00:05:02,102 --> 00:05:05,504
The ball is now ready
to receive its stripes.
77
00:05:05,506 --> 00:05:08,006
The worker paints black rubber
into grooves
78
00:05:08,008 --> 00:05:10,575
that were formed
during embossing.
79
00:05:10,577 --> 00:05:15,047
This rubber quickly cures
to become part of the ball.
80
00:05:15,049 --> 00:05:18,517
Another worker inserts
a fill valve into the hole.
81
00:05:18,519 --> 00:05:22,454
Then, mechanical fists
squeeze the ball to deflate it.
82
00:05:22,456 --> 00:05:24,790
This prepares it for packaging.
83
00:05:24,792 --> 00:05:28,026
With the valve inside,
it can be easily re-inflated
84
00:05:28,028 --> 00:05:31,396
by the customer.
85
00:05:31,398 --> 00:05:35,200
A worker wraps it in plastic
and ships it to the retailer.
86
00:05:37,304 --> 00:05:39,805
Making this rubber basketball
has only taken
87
00:05:39,807 --> 00:05:41,239
a couple of hours,
88
00:05:41,241 --> 00:05:43,675
but it should be able
to take a lot of knocks
89
00:05:43,677 --> 00:05:45,510
and bounce right back.
90
00:05:57,991 --> 00:05:59,925
Narrator:
Having a desk job
91
00:05:59,927 --> 00:06:02,327
doesn't mean
one has to sit still.
92
00:06:02,329 --> 00:06:05,530
With a motion chair, the office
worker can keep moving
93
00:06:05,532 --> 00:06:07,632
while staying seated.
94
00:06:07,634 --> 00:06:11,069
The support structure is
engineered for flexibility,
95
00:06:11,071 --> 00:06:15,207
so while sitting, a person
can bounce, tilt, and sway.
96
00:06:19,246 --> 00:06:22,647
Motion chairs redefine
the act of sitting.
97
00:06:22,649 --> 00:06:24,149
The stem is springy,
98
00:06:24,151 --> 00:06:26,651
and the connection
to the seat is elastic.
99
00:06:26,653 --> 00:06:31,123
This allows the office worker
to be active while sitting.
100
00:06:31,125 --> 00:06:35,026
Making a motion chair starts
with glass-reinforced plastic,
101
00:06:35,028 --> 00:06:38,096
which is a strong
and lightweight material.
102
00:06:38,098 --> 00:06:41,900
These granules will be used
to make the core of the seat.
103
00:06:41,902 --> 00:06:46,905
A robot inserts a steel fastener
in the center of the seat mold.
104
00:06:46,907 --> 00:06:50,175
The mold closes, and the machine
melts the plastic
105
00:06:50,177 --> 00:06:52,744
and injects it into the mold.
106
00:06:52,746 --> 00:06:56,314
The plastic quickly solidifies
around the steel fastener,
107
00:06:56,316 --> 00:06:59,985
and it becomes part
of the seat core.
108
00:06:59,987 --> 00:07:02,254
A robot with suctioning grippers
109
00:07:02,256 --> 00:07:07,058
pulls the convex-shaped
seat core out.
110
00:07:07,060 --> 00:07:08,894
A worker assembles
a height-adjustment
111
00:07:08,896 --> 00:07:12,330
lever in the hole beside
the one for the seat stem.
112
00:07:15,335 --> 00:07:18,503
A molded plastic top
completes the seat core.
113
00:07:22,042 --> 00:07:25,143
He anchors it to the core
with numerous screws,
114
00:07:25,145 --> 00:07:31,049
so even with heavy use, the top
should stay firmly in place.
115
00:07:31,051 --> 00:07:34,019
He visually inspects
the seat core and confirms
116
00:07:34,021 --> 00:07:36,521
that it looks solid.
117
00:07:38,926 --> 00:07:42,961
Cushioning foam and fabric
complete the seat.
118
00:07:42,963 --> 00:07:46,231
A worker assembles roller
mechanisms that will facilitate
119
00:07:46,233 --> 00:07:49,968
the vertical movements
of the chair's stem.
120
00:07:49,970 --> 00:07:54,139
Using a special assembly tool,
she presses the plastic roller
121
00:07:54,141 --> 00:07:57,976
and two end brackets
on a metal cylinder.
122
00:07:57,978 --> 00:08:01,379
She then applies an index
to an aluminum support column
123
00:08:01,381 --> 00:08:02,647
that serves as a guide
124
00:08:02,649 --> 00:08:05,684
for setting the tension
of an outer spring.
125
00:08:05,686 --> 00:08:08,453
She inserts the roller
mechanisms in slots
126
00:08:08,455 --> 00:08:10,655
at the other end of the column.
127
00:08:10,657 --> 00:08:13,892
Strips of fabric tape
keep the rollers in place.
128
00:08:18,031 --> 00:08:21,600
An air cylinder presses
the outer sleeve onto the column
129
00:08:21,602 --> 00:08:25,370
so that it sits above
the tension index.
130
00:08:25,372 --> 00:08:27,806
A screw between
the inner and outer cylinders
131
00:08:27,808 --> 00:08:31,042
keeps them in position.
132
00:08:31,044 --> 00:08:33,178
Next up is a compression part
133
00:08:33,180 --> 00:08:36,047
for setting the position
of the outer seat spring.
134
00:08:38,418 --> 00:08:41,720
A worker slides a metal ring
between the compression part
135
00:08:41,722 --> 00:08:43,655
and the support column.
136
00:08:43,657 --> 00:08:47,759
He inserts a gas spring into
the double-walled seat stem.
137
00:08:49,997 --> 00:08:53,131
He now slides the outer
spring onto the assembly.
138
00:08:55,936 --> 00:08:59,571
He installs a plastic casing
over the gas spring.
139
00:08:59,573 --> 00:09:04,209
Then he puts the seat stem
inside a press chamber.
140
00:09:04,211 --> 00:09:07,279
He adds a top collar
to the center of the gas spring
141
00:09:07,281 --> 00:09:09,080
as well as a snap ring.
142
00:09:12,219 --> 00:09:16,221
He activates the press, and
it squeezes everything together.
143
00:09:18,926 --> 00:09:21,893
Next is a stand with
flexible rubber parts
144
00:09:21,895 --> 00:09:26,965
that will make lateral
movement possible while sitting.
145
00:09:26,967 --> 00:09:31,169
The worker attaches the flexible
stand to a circular base.
146
00:09:31,171 --> 00:09:34,339
He confirms that holes
for rolling casters or gliders
147
00:09:34,341 --> 00:09:36,908
in the base are
the correct dimension.
148
00:09:39,012 --> 00:09:41,646
He screws a dial
for setting lateral movement
149
00:09:41,648 --> 00:09:44,416
onto the protruding fastener.
150
00:09:44,418 --> 00:09:49,020
He secures it with a nut
and tightens it.
151
00:09:49,022 --> 00:09:51,389
He covers the nut
with a rubber cap.
152
00:09:53,727 --> 00:09:57,929
A tester will now evaluate
the motion chair's performance.
153
00:09:57,931 --> 00:10:00,999
He attaches the stem
to the base,
154
00:10:01,001 --> 00:10:04,135
and he fastens the seat
to the protruding rod.
155
00:10:06,173 --> 00:10:10,875
He sits down and bounces around
to test the range of movement.
156
00:10:10,877 --> 00:10:13,745
These tests are done
intermittently to confirm
157
00:10:13,747 --> 00:10:17,949
that the the product
consistently meets requirements.
158
00:10:17,951 --> 00:10:20,952
This motion chair is now ready
for shipping.
159
00:10:22,956 --> 00:10:25,757
The packer plugs a hole
in the base ring.
160
00:10:25,759 --> 00:10:28,827
This hole is for attaching
an optional backrest.
161
00:10:30,998 --> 00:10:33,698
He applies a sticker
with the product name.
162
00:10:36,003 --> 00:10:37,836
All of the parts
of the motion chair
163
00:10:37,838 --> 00:10:42,307
can be easily assembled
on location.
164
00:10:42,309 --> 00:10:45,977
Designed to discourage rigid
sitting and encourage movement
165
00:10:45,979 --> 00:10:47,679
in any direction,
166
00:10:47,681 --> 00:10:49,748
it will compel
the person using it
167
00:10:49,750 --> 00:10:52,117
to use his or her core muscles
168
00:10:52,119 --> 00:10:55,086
and be less sedentary
on the job.
169
00:10:55,088 --> 00:10:57,956
With the motion chair,
it just may be possible
170
00:10:57,958 --> 00:11:00,258
to get fit while you sit.
171
00:11:11,705 --> 00:11:13,271
Narrator:
For at least a century,
172
00:11:13,273 --> 00:11:15,006
montreal's jewish delis
173
00:11:15,008 --> 00:11:17,709
have been serving
smoked meat on rye.
174
00:11:17,711 --> 00:11:20,345
The exact origins of this
particular deli meat
175
00:11:20,347 --> 00:11:23,848
are a matter of debate with
many claims to its invention.
176
00:11:23,850 --> 00:11:26,484
The juicy details
have been lost to time,
177
00:11:26,486 --> 00:11:28,086
but montreal smoked meat
178
00:11:28,088 --> 00:11:30,722
continues to have
an enduring appeal.
179
00:11:33,293 --> 00:11:36,127
A cross between corn beef
and pastrami,
180
00:11:36,129 --> 00:11:37,796
montreal smoked meat
181
00:11:37,798 --> 00:11:40,799
has attracted a foodie
following around the world.
182
00:11:43,336 --> 00:11:46,337
Montreal smoked meat
starts with brisket,
183
00:11:46,339 --> 00:11:49,340
which is a cut from
the cow's upper chest.
184
00:11:49,342 --> 00:11:52,243
A worker thaws
the previously frozen briskets
185
00:11:52,245 --> 00:11:56,281
in a refrigerator for 10 hours.
186
00:11:56,283 --> 00:11:58,950
A team slices off
the biggest chunks of fat
187
00:11:58,952 --> 00:12:02,487
using round, air-powered blades.
188
00:12:02,489 --> 00:12:05,190
The excess fat will be shipped
to another factory
189
00:12:05,192 --> 00:12:07,325
and used to make soap.
190
00:12:07,327 --> 00:12:09,527
The workers use a sharp
butcher's knife
191
00:12:09,529 --> 00:12:11,563
to remove smaller pieces of fat,
192
00:12:11,565 --> 00:12:14,499
leaving just enough for flavor.
193
00:12:14,501 --> 00:12:17,235
Next, they prepare the brine.
194
00:12:17,237 --> 00:12:20,338
Along with salt and sugar,
there's a secret recipe
195
00:12:20,340 --> 00:12:22,607
of spices that
includes peppers,
196
00:12:22,609 --> 00:12:26,411
mustard seed,
allspice, and cinnamon.
197
00:12:26,413 --> 00:12:29,013
The operator combines
the salt and sugar
198
00:12:29,015 --> 00:12:32,484
with ice-cold water
in a high-speed mixer.
199
00:12:32,486 --> 00:12:34,786
The spices have been
premixed in water
200
00:12:34,788 --> 00:12:38,356
to produce a spice concentrate.
201
00:12:38,358 --> 00:12:40,725
The next worker loads
the trimmed briskets
202
00:12:40,727 --> 00:12:43,328
onto a conveyor.
203
00:12:43,330 --> 00:12:46,831
It takes the briskets under
an array of long needles
204
00:12:46,833 --> 00:12:52,103
that inject the brine
into the meat repeatedly.
205
00:12:52,105 --> 00:12:56,307
Laced with brine, the briskets
then fall into a bin.
206
00:12:56,309 --> 00:13:00,712
A worker transfers the juicy
briskets into a vacuum tumbler.
207
00:13:00,714 --> 00:13:02,380
It pulls air from the chamber,
208
00:13:02,382 --> 00:13:05,683
causing the briskets
to absorb more brine.
209
00:13:05,685 --> 00:13:08,586
The tumbler tosses
the briskets for 10 hours,
210
00:13:08,588 --> 00:13:10,755
massaging the brine
into the meat.
211
00:13:10,757 --> 00:13:13,958
A layer of protein also
forms on the surface.
212
00:13:13,960 --> 00:13:17,362
This holds the brine in place.
213
00:13:17,364 --> 00:13:22,066
In the meantime, a worker mixes
the ingredients for the dry rub.
214
00:13:22,068 --> 00:13:23,968
It's comprised of the same
spices
215
00:13:23,970 --> 00:13:25,703
that were used in the brine
216
00:13:25,705 --> 00:13:28,006
along with clumps
of fresh garlic.
217
00:13:31,411 --> 00:13:33,978
After the briskets have been
well marinated,
218
00:13:33,980 --> 00:13:36,514
the operator adds the dry rub.
219
00:13:36,516 --> 00:13:39,684
He turns on the tumbler
for another half hour.
220
00:13:39,686 --> 00:13:44,422
The dry rub mixture coats
the surface of the meat.
221
00:13:44,424 --> 00:13:46,090
This system is an alternative
222
00:13:46,092 --> 00:13:49,227
to rubbing the spices
onto the briskets by hand.
223
00:13:49,229 --> 00:13:51,663
It's faster and very efficient.
224
00:13:53,700 --> 00:13:55,633
Coated with smoked meat spices
225
00:13:55,635 --> 00:13:57,936
and injected
with flavorful brine,
226
00:13:57,938 --> 00:14:00,405
the briskets are now
ready for roasting.
227
00:14:04,477 --> 00:14:10,481
An employee rolls racks of the
spicy briskets into a huge oven.
228
00:14:10,483 --> 00:14:14,185
The briskets steam-roast
at 210 degrees fahrenheit
229
00:14:14,187 --> 00:14:17,288
for 8 to 10 hours,
230
00:14:17,290 --> 00:14:20,225
but the workers don't
actually smoke the briskets.
231
00:14:20,227 --> 00:14:22,360
It's the spices and brine
that give them
232
00:14:22,362 --> 00:14:26,364
that montreal
smoked meat flavor.
233
00:14:26,366 --> 00:14:28,533
After the briskets
have been chilled,
234
00:14:28,535 --> 00:14:31,102
workers transfer them
to plastic bags
235
00:14:31,104 --> 00:14:33,938
and place them on a conveyor.
236
00:14:33,940 --> 00:14:38,109
Moving forward, a vacuum-sealing
head drops down to shrink-wrap
237
00:14:38,111 --> 00:14:40,311
the plastic to the meat.
238
00:14:40,313 --> 00:14:43,581
The vacuum seal and the
smoked meat spices combined
239
00:14:43,583 --> 00:14:46,351
give the meat a long shelf life.
240
00:14:46,353 --> 00:14:51,022
Refrigerated, it will stay fresh
for up to 45 days.
241
00:14:51,024 --> 00:14:54,325
This plant ships the entire
brisket to restaurants.
242
00:14:54,327 --> 00:14:57,095
At the restaurant,
they will re-steam and slice
243
00:14:57,097 --> 00:14:59,364
the brisket before serving.
244
00:14:59,366 --> 00:15:01,833
Next, the smoked meat
is pre-sliced
245
00:15:01,835 --> 00:15:03,701
to sell in supermarkets.
246
00:15:03,703 --> 00:15:09,440
An automatic meat slicer carves
it into thin pieces in seconds.
247
00:15:09,442 --> 00:15:12,243
A worker retrieves
the sliced smoked meat
248
00:15:12,245 --> 00:15:15,413
and sets it on a tray.
249
00:15:15,415 --> 00:15:17,415
Transferred to a weigh station,
250
00:15:17,417 --> 00:15:22,587
workers divide the slices
into 6-ounce portions.
251
00:15:22,589 --> 00:15:26,257
Then they roll up
the smoked meat slices.
252
00:15:26,259 --> 00:15:32,263
A worker places the rolled meat
into plastic pouches on a rack.
253
00:15:32,265 --> 00:15:33,831
The racks move forward,
254
00:15:33,833 --> 00:15:36,534
and a vacuum sealer
applies a top film,
255
00:15:36,536 --> 00:15:41,372
creating little packets
of sliced smoked meat.
256
00:15:41,374 --> 00:15:44,442
After a quick bake
to pasteurize the meat,
257
00:15:44,444 --> 00:15:48,346
he puts six packets into
compartments on a conveyor.
258
00:15:48,348 --> 00:15:53,284
A pusher moves the six packets
of smoked meat into an open box.
259
00:15:53,286 --> 00:15:56,587
The system seals the ends
of the boxes.
260
00:15:56,589 --> 00:16:01,225
Workers weigh the box
of smoked meat slices.
261
00:16:01,227 --> 00:16:03,027
It has taken about 30 hours
262
00:16:03,029 --> 00:16:06,731
to produce this batch
of montreal smoked meat.
263
00:16:06,733 --> 00:16:09,767
It's time to slice it thin
and pile it thick
264
00:16:09,769 --> 00:16:13,004
between slabs
of mustard-slathered rye.
265
00:16:13,006 --> 00:16:16,541
Now, that's a deli lunch,
montreal-style.
266
00:16:30,123 --> 00:16:32,490
Narrator: A motorized scooter
is a souped-up version
267
00:16:32,492 --> 00:16:34,225
of an ordinary scooter.
268
00:16:34,227 --> 00:16:36,928
Instead of propelling the wheels
by pushing off the ground
269
00:16:36,930 --> 00:16:40,231
with one leg,
an engine does most of the work.
270
00:16:40,233 --> 00:16:42,867
Some motorized scooters
are kids' toys,
271
00:16:42,869 --> 00:16:44,969
but others are sturdy vehicles
272
00:16:44,971 --> 00:16:48,439
suitable for commuting,
utility, and recreation.
273
00:16:50,577 --> 00:16:52,076
This motorized scooter
274
00:16:52,078 --> 00:16:55,113
has wheels large enough
and tires wide enough
275
00:16:55,115 --> 00:17:00,018
to drive on any surface,
even off road.
276
00:17:00,020 --> 00:17:02,720
The manufacturer contracts
this factory
277
00:17:02,722 --> 00:17:04,989
to make the frame components.
278
00:17:04,991 --> 00:17:08,826
Machines cut hollow steel tubes
to the required length.
279
00:17:08,828 --> 00:17:12,263
Then workers program
an automated bending machine
280
00:17:12,265 --> 00:17:15,099
to bend each one
to the required shape.
281
00:17:19,973 --> 00:17:23,107
They make five tubular
frame parts per scooter,
282
00:17:23,109 --> 00:17:25,543
strictly following the
technical drawing supplied
283
00:17:25,545 --> 00:17:29,414
by the manufacturer.
284
00:17:29,416 --> 00:17:32,183
The scooter company subcontracts
the frame assembly
285
00:17:32,185 --> 00:17:34,385
to another factory.
286
00:17:34,387 --> 00:17:37,555
There, a welder mounts
the components on a jig,
287
00:17:37,557 --> 00:17:42,560
which positions them correctly
while he welds them together.
288
00:17:42,562 --> 00:17:46,564
The non-tubular, flat-frame
parts are prepared in house,
289
00:17:46,566 --> 00:17:49,967
cut from sheet steel by
a computer-guided laser cutter.
290
00:17:52,405 --> 00:17:55,006
These flat crossbars
support the footboard
291
00:17:55,008 --> 00:17:58,376
on which the rider stands.
292
00:17:58,378 --> 00:18:00,978
This flat plate
supports the battery,
293
00:18:00,980 --> 00:18:05,383
and these arms support
the rear wheel and motor.
294
00:18:05,385 --> 00:18:08,386
After applying a coat
of anticorrosion paint,
295
00:18:08,388 --> 00:18:10,555
workers install
the side reflectors
296
00:18:10,557 --> 00:18:13,391
and the knob
that secures the battery.
297
00:18:13,393 --> 00:18:17,929
The paint is baked on
for maximum durability.
298
00:18:17,931 --> 00:18:21,332
The scooter manufacturer
subcontracts the wheel rims
299
00:18:21,334 --> 00:18:22,667
to another factory
300
00:18:22,669 --> 00:18:26,304
that specializes in
high-precision metal spinning.
301
00:18:26,306 --> 00:18:28,673
A worker there mounts
an aluminum disk
302
00:18:28,675 --> 00:18:30,975
onto a computer-guided lathe,
303
00:18:30,977 --> 00:18:35,279
positioning it right next
to a rim-shaped steel mold.
304
00:18:35,281 --> 00:18:38,649
Two rollers push and stretch
the disk over the mold,
305
00:18:38,651 --> 00:18:41,152
forming the aluminum
to the rim's shape.
306
00:18:43,756 --> 00:18:47,358
Another worker mounts the rim
on a manual-spinning lathe
307
00:18:47,360 --> 00:18:49,494
to finish the shaping.
308
00:18:49,496 --> 00:18:54,699
First, with a cutting knife,
he trims the edge.
309
00:18:54,701 --> 00:18:57,068
After lubricating
the edge with soap,
310
00:18:57,070 --> 00:19:01,072
he uses a forming bar
to turn it inward to form a lip.
311
00:19:03,743 --> 00:19:05,510
Then, with the forming roller,
312
00:19:05,512 --> 00:19:08,713
he stretches the lip
to shape a flange.
313
00:19:16,689 --> 00:19:19,790
back at the scooter factory,
a worker begins installing
314
00:19:19,792 --> 00:19:22,426
the vehicle's silent
electric motor.
315
00:19:22,428 --> 00:19:25,129
Its cable will plug into
the electronic module
316
00:19:25,131 --> 00:19:29,534
that runs the motor,
accelerator, and battery.
317
00:19:29,536 --> 00:19:32,170
The motor is actually located
inside the hub
318
00:19:32,172 --> 00:19:33,738
of the rear wheel.
319
00:19:33,740 --> 00:19:37,441
This mounting ring
holds it in place.
320
00:19:37,443 --> 00:19:40,511
He installs a brake disc
on top of the motor
321
00:19:40,513 --> 00:19:42,513
and another on the front wheel.
322
00:19:42,515 --> 00:19:45,883
A mechanical cable connects
each handlebar brake lever
323
00:19:45,885 --> 00:19:47,251
to the brake calipers.
324
00:19:47,253 --> 00:19:50,888
When the driver pulls the
levers, the brake calipers clamp
325
00:19:50,890 --> 00:19:54,592
the discs to the wheels,
stopping rotation.
326
00:19:54,594 --> 00:19:56,861
Now the final assembly --
327
00:19:56,863 --> 00:20:01,065
workers bolt the rear wheel
to the frame's support arms.
328
00:20:01,067 --> 00:20:03,201
They insert
the height-adjustable fork,
329
00:20:03,203 --> 00:20:06,537
made of steel and aluminum,
into the steering column.
330
00:20:06,539 --> 00:20:09,173
Next, the worker installs
the handlebars,
331
00:20:09,175 --> 00:20:11,809
which have a thumb-operated
accelerator throttle,
332
00:20:11,811 --> 00:20:14,679
an lcd monitor
and two hand brakes,
333
00:20:14,681 --> 00:20:17,648
each with a mechanical
cable for the calipers.
334
00:20:17,650 --> 00:20:20,918
Each hand brake
also has one electrical cable.
335
00:20:20,920 --> 00:20:22,320
He connects the throttle line
336
00:20:22,322 --> 00:20:24,922
and the electrical cables
to the monitor.
337
00:20:24,924 --> 00:20:28,192
Then he connects the monitor
to the controller.
338
00:20:28,194 --> 00:20:29,694
When the rider brakes,
339
00:20:29,696 --> 00:20:32,463
the controller
also cuts power to the motor,
340
00:20:32,465 --> 00:20:35,967
which allows the scooter's
48-volt lithium ion battery
341
00:20:35,969 --> 00:20:39,370
to regenerate.
342
00:20:39,372 --> 00:20:41,305
This screw knob holds
the battery
343
00:20:41,307 --> 00:20:44,709
securely against
the battery support plate.
344
00:20:44,711 --> 00:20:47,044
He connects the battery
to the controller,
345
00:20:47,046 --> 00:20:50,181
then the mechanical cable
from one hand-brake lever
346
00:20:50,183 --> 00:20:51,849
to the front brake calipers
347
00:20:51,851 --> 00:20:55,219
and from the other hand brake
