1
00:00:53,454 --> 00:00:55,287
An innerspring mattress
2
00:00:55,289 --> 00:00:57,122
is made with steel-wire springs
3
00:00:57,124 --> 00:01:00,059
to support
a person's body weight.
4
00:01:00,061 --> 00:01:02,361
The quality of the mattress
is usually determined
5
00:01:02,363 --> 00:01:04,463
by the thickness
of the steel wire,
6
00:01:04,465 --> 00:01:05,998
the number of springs,
7
00:01:06,000 --> 00:01:08,867
and how the springs
are configured and linked
8
00:01:08,869 --> 00:01:10,769
to form the inner
support system.
9
00:01:13,474 --> 00:01:17,276
Most of this innerspring
mattress is crafted by hand.
10
00:01:17,278 --> 00:01:20,679
The material in between the
springs contains multiple layers
11
00:01:20,681 --> 00:01:23,982
of batting made from a blend
of polyester fiber
12
00:01:23,984 --> 00:01:26,418
and organic cotton fiber.
13
00:01:27,721 --> 00:01:30,289
Cotton allows the batting
to be breathable,
14
00:01:30,291 --> 00:01:33,058
so the mattress
won't trap body heat.
15
00:01:33,060 --> 00:01:35,694
Polyester prevents
the cotton from matting,
16
00:01:35,696 --> 00:01:39,198
so the batting
doesn't flatten over time.
17
00:01:39,200 --> 00:01:43,402
This machine feeds both
materials to a carding machine.
18
00:01:44,472 --> 00:01:47,172
At the first station,
rollers and cylinders
19
00:01:47,174 --> 00:01:51,143
with metal teeth open
and comb out the fibers.
20
00:01:52,012 --> 00:01:53,946
Next, the blended poly cotton
21
00:01:53,948 --> 00:01:57,015
is formed into a thin,
fluffy sheet.
22
00:01:58,352 --> 00:02:00,652
The next station
layers the sheet.
23
00:02:03,290 --> 00:02:06,525
Rollers compress the layers
to form a thicker sheet
24
00:02:06,527 --> 00:02:09,194
about 2 3/4 inches high.
25
00:02:09,196 --> 00:02:11,763
The machine cuts the sheet
to the width and length
26
00:02:11,765 --> 00:02:14,133
of the specified mattress.
27
00:02:14,135 --> 00:02:17,302
A technician places
the finished bat on a scale
28
00:02:17,304 --> 00:02:20,839
to ensure it hits
the target weight.
29
00:02:20,841 --> 00:02:23,509
He piles 18 bats on a cart,
30
00:02:23,511 --> 00:02:27,346
which is how many are required
for just one mattress.
31
00:02:27,348 --> 00:02:29,114
Meanwhile, another technician
32
00:02:29,116 --> 00:02:31,450
builds the mattress's
support structure,
33
00:02:31,452 --> 00:02:34,186
known as the innerspring unit.
34
00:02:34,188 --> 00:02:38,023
A coiling machine pulls
spring-steel wire off a spool,
35
00:02:38,025 --> 00:02:41,059
then winds
and cuts it into coils.
36
00:02:41,061 --> 00:02:43,929
The top and the bottom
of each coil are crimped,
37
00:02:43,931 --> 00:02:46,465
creating inter-connection areas.
38
00:02:48,002 --> 00:02:50,669
A technician inserts
spring-steel wire
39
00:02:50,671 --> 00:02:55,140
into a lacing machine and places
a row of coils on a table.
40
00:02:55,142 --> 00:02:58,043
As the machine advances,
the helical wire
41
00:02:58,045 --> 00:03:00,846
catches the coils at the points
where they're crimped,
42
00:03:00,848 --> 00:03:03,415
lacing them together.
43
00:03:03,417 --> 00:03:06,151
The process is repeated until
the spring structure
44
00:03:06,153 --> 00:03:08,820
is the size of the mattress.
45
00:03:08,822 --> 00:03:14,193
The perimeter of the mattress is
framed with more helical wire.
46
00:03:14,195 --> 00:03:17,996
He fabric surface of a mattress
is known as the ticking.
47
00:03:17,998 --> 00:03:20,299
A seamstress marks
the required dimensions
48
00:03:20,301 --> 00:03:23,502
on a stack of cotton fabric.
49
00:03:23,504 --> 00:03:25,537
Using a rotary cutting blade,
50
00:03:25,539 --> 00:03:29,274
she cuts the ticking fabric
along the marked dimensions.
51
00:03:32,746 --> 00:03:36,081
A sewer hems the edges
of all three panels.
52
00:03:36,083 --> 00:03:39,418
This step will strengthen
the connected seams.
53
00:03:39,420 --> 00:03:42,321
He also sews on the labels
listing the product
54
00:03:42,323 --> 00:03:44,590
and safety information.
55
00:03:44,592 --> 00:03:47,359
The side wall consists
of four layers --
56
00:03:47,361 --> 00:03:51,697
the ticking, two types of bats,
and a backing fabric.
57
00:03:51,699 --> 00:03:55,267
A seamstress pulls the layers
through a stamping machine,
58
00:03:55,269 --> 00:03:57,903
which fastens the layers
together with a pair
59
00:03:57,905 --> 00:04:02,174
of brass eyelets
every 2 3/4 inches.
60
00:04:02,176 --> 00:04:04,076
Using another stamping machine,
61
00:04:04,078 --> 00:04:08,380
she attaches cord handles
with large brass grommets.
62
00:04:08,382 --> 00:04:11,083
The handles make it easier
to flip and rotate
63
00:04:11,085 --> 00:04:14,086
the mattress
to ensure even wear.
64
00:04:17,424 --> 00:04:20,192
Another technician covers
the innerspring unit
65
00:04:20,194 --> 00:04:21,994
with a lightweight fabric
66
00:04:21,996 --> 00:04:26,398
and pads the corners with
batting to prevent indentation.
67
00:04:27,434 --> 00:04:30,535
He attaches the fabric backing
of the side wall
68
00:04:30,537 --> 00:04:33,372
to the wire perimeter
of the innerspring unit
69
00:04:33,374 --> 00:04:35,340
with hog-ring staples.
70
00:04:37,344 --> 00:04:40,545
He tops this side of
the mattress with nine bats,
71
00:04:40,547 --> 00:04:44,016
equivalent to 27.5 inches
of padding.
72
00:04:45,653 --> 00:04:47,953
He trims each bat by hand,
73
00:04:47,955 --> 00:04:51,923
gradually narrowing the layers
as he works his way downward,
74
00:04:51,925 --> 00:04:54,626
creating a tapered shape.
75
00:04:54,628 --> 00:04:58,263
Then a polyester fabric layer
is added for comfort,
76
00:04:58,265 --> 00:05:02,534
and a non-woven flame-resistant
barrier fabric layer on top.
77
00:05:03,370 --> 00:05:05,370
The ticking
is put into position,
78
00:05:05,372 --> 00:05:08,607
and the excess filling
is trimmed.
79
00:05:08,609 --> 00:05:11,076
The technician pulls
the ticking and pins it
80
00:05:11,078 --> 00:05:13,445
to the top of the side wall.
81
00:05:14,682 --> 00:05:15,981
He flips the mattress
82
00:05:15,983 --> 00:05:18,717
and repeats the process
on the other side.
83
00:05:22,823 --> 00:05:25,190
Using an industrial
sewing machine,
84
00:05:25,192 --> 00:05:27,426
he sews the top
and bottom tickings
85
00:05:27,428 --> 00:05:31,063
to the side wall with edge tape.
86
00:05:31,065 --> 00:05:34,566
Woven cotton ticking is more
durable than knitted cotton.
87
00:05:37,571 --> 00:05:41,573
Finally, the automated machine
tufts the mattress and inserts
88
00:05:41,575 --> 00:05:43,675
a woven band through the middle,
89
00:05:43,677 --> 00:05:47,979
locking each tuft in place
with a pom-pom on both sides.
90
00:05:47,981 --> 00:05:51,016
This prevents the materials
inside from shifting
91
00:05:51,018 --> 00:05:53,352
and sets the level of firmness.
92
00:06:09,770 --> 00:06:13,171
Stand-up paddling has become a popular sport,
93
00:06:13,173 --> 00:06:17,209
but paddleboards have been
around for over 3,000 years.
94
00:06:17,211 --> 00:06:21,046
Contemporary boards rely on
modern materials
95
00:06:21,048 --> 00:06:25,183
to make light and reliable
paddleboards suited for leisure
96
00:06:25,185 --> 00:06:27,185
as well as for competition.
97
00:06:30,624 --> 00:06:33,392
This paddleboard is made
with vinyl-ester resin
98
00:06:33,394 --> 00:06:35,460
and laminated fiberglass.
99
00:06:35,462 --> 00:06:38,764
It's equipped with an onboard
lighting system, an anchor,
100
00:06:38,766 --> 00:06:41,900
and a neoprene rubber
non-slip pad.
101
00:06:41,902 --> 00:06:43,568
In the gel-coating room,
102
00:06:43,570 --> 00:06:45,604
a technician wipes
a release agent
103
00:06:45,606 --> 00:06:50,842
on the paddleboard mold to make
the surface smooth and clean.
104
00:06:50,844 --> 00:06:54,312
Another technician positions
the fin channel on the mold
105
00:06:54,314 --> 00:06:57,416
using a thin fiberglass
template as a guide.
106
00:07:01,021 --> 00:07:04,222
He uses an airless pumping
system to spray the mold
107
00:07:04,224 --> 00:07:07,659
with a vinyl-ester gel
coating mixed with hardener.
108
00:07:12,766 --> 00:07:16,401
he takes a mil gauge to make
sure the hull thickness is even.
109
00:07:19,006 --> 00:07:20,505
A technician prepares to make
110
00:07:20,507 --> 00:07:23,074
the first structural layer
of the hull,
111
00:07:23,076 --> 00:07:27,446
using a 3/4-ounce
bi-directional fiberglass mat.
112
00:07:27,448 --> 00:07:30,415
First, he pulls out a panel
of fiberglass
113
00:07:30,417 --> 00:07:33,218
and covers
the gel-coated surface.
114
00:07:33,220 --> 00:07:36,254
Using fabric scissors,
he cuts the mat
115
00:07:36,256 --> 00:07:39,458
and makes the fiberglass skin
as tight as possible.
116
00:07:42,963 --> 00:07:44,696
He tears the mat to conform it
117
00:07:44,698 --> 00:07:47,232
to the rounded shape
of the gel coat
118
00:07:47,234 --> 00:07:49,835
and fits the mat
to the edge of the hull.
119
00:07:52,139 --> 00:07:55,907
He applies vinyl-ester resin
with a paint roller.
120
00:07:55,909 --> 00:07:58,477
The resin saturates
the fiberglass,
121
00:07:58,479 --> 00:08:00,846
which merges
with the gel coating.
122
00:08:02,983 --> 00:08:05,851
Extra material is placed
over the fin channel
123
00:08:05,853 --> 00:08:07,752
to strength the structural bond
124
00:08:07,754 --> 00:08:10,121
between the channel
and the hull.
125
00:08:13,660 --> 00:08:16,294
Then the technician uses
a bubble roller
126
00:08:16,296 --> 00:08:18,730
to push out air bubbles.
127
00:08:19,967 --> 00:08:22,534
He applies a second coat
of fiberglass
128
00:08:22,536 --> 00:08:26,638
to reinforce the structural
integrity of the board.
129
00:08:27,608 --> 00:08:29,074
In the assembly room,
130
00:08:29,076 --> 00:08:32,277
another technician fits
a template on the board deck
131
00:08:32,279 --> 00:08:36,181
and traces the contours of the
hand-grab mount with a pencil.
132
00:08:39,887 --> 00:08:42,454
He uses an air saw
to cut out a slot
133
00:08:42,456 --> 00:08:46,091
in the fiberglass laminate
to fit the hand-grab mount.
134
00:08:50,998 --> 00:08:52,664
he binds the hand-grab mount
135
00:08:52,666 --> 00:08:56,501
to the hull with a coat
of vinyl-ester resin.
136
00:08:56,503 --> 00:09:00,505
Within about 20 minutes,
the laminate hardens.
137
00:09:01,875 --> 00:09:05,176
Next, plastic tubing for
the internal anchoring system
138
00:09:05,178 --> 00:09:06,511
is installed.
139
00:09:06,513 --> 00:09:09,714
A technician applies a bonding
adhesive to the tube,
140
00:09:09,716 --> 00:09:11,616
securing it in place.
141
00:09:11,618 --> 00:09:14,085
He attaches the tube
with tie wraps
142
00:09:14,087 --> 00:09:16,855
so it doesn't get
tangled inside the hull.
143
00:09:19,927 --> 00:09:22,827
He installs a jam cleat
for the rope that will allow
144
00:09:22,829 --> 00:09:26,364
the paddler to manually control
the anchor from the deck.
145
00:09:32,973 --> 00:09:35,440
the hull's cured
vinyl-ester resin
146
00:09:35,442 --> 00:09:39,945
is now firmly bonded
to the structural laminate.
147
00:09:39,947 --> 00:09:43,582
The assembler applies expanding
adhesive and positions
148
00:09:43,584 --> 00:09:48,053
an expanded polypropylene foam
stringer inside the hull.
149
00:09:48,055 --> 00:09:51,222
The foam stringers are
the backbone of the board.
150
00:09:51,224 --> 00:09:53,959
They support the weight
of the paddler on the deck
151
00:09:53,961 --> 00:09:57,295
while keeping the board
as light as possible.
152
00:09:57,297 --> 00:10:00,298
Using a nylon wedge
and a rubber mallet,
153
00:10:00,300 --> 00:10:03,168
the assembler removes
the mold from the hull.
154
00:10:03,170 --> 00:10:05,103
Since the hull
is so lightweight,
155
00:10:05,105 --> 00:10:09,608
two assemblers can lift
and flip it on to a cart.
156
00:10:09,610 --> 00:10:12,377
An assembler trims off
the excess laminate
157
00:10:12,379 --> 00:10:16,881
using an air cutter fitted
with a diamond cutting blade.
158
00:10:16,883 --> 00:10:20,085
He levels the foam stringers
with a file blade,
159
00:10:20,087 --> 00:10:24,422
ensuring the tightest possible
fit between the hull and deck.
160
00:10:25,559 --> 00:10:28,893
He applies expanding foam
adhesive on the stringers
161
00:10:28,895 --> 00:10:31,129
before he places
the deck on the foam
162
00:10:31,131 --> 00:10:33,565
with the help of a co-worker.
163
00:10:33,567 --> 00:10:37,802
The adhesive quickly binds
the parts together.
164
00:10:37,804 --> 00:10:41,239
The vinyl rub rail designed
as a side protection
165
00:10:41,241 --> 00:10:44,242
masks the joint between
the deck and the hull.
166
00:10:46,847 --> 00:10:49,414
The hull contains
a dry storage hatch
167
00:10:49,416 --> 00:10:52,550
where the onboard battery
is housed.
168
00:10:52,552 --> 00:10:55,987
The 8 amp hour battery
can activate the power pull,
169
00:10:55,989 --> 00:10:59,824
a microanchor designed
for shallow waters.
170
00:10:59,826 --> 00:11:03,128
In deeper waters, a paddler
can manually activate
171
00:11:03,130 --> 00:11:07,932
the internal anchor system
with a 16-foot nylon cord.
172
00:11:07,934 --> 00:11:11,202
Finally, this board is ready
to hit the water.
173
00:11:24,451 --> 00:11:27,552
narrator: Invented in 1901
by a british engineer,
174
00:11:27,554 --> 00:11:31,389
the vacuum cleaner
was considered a game changer.
175
00:11:31,391 --> 00:11:34,092
The original versions were made
substantially heavier
176
00:11:34,094 --> 00:11:36,728
than the vacuums built today.
177
00:11:36,730 --> 00:11:39,831
In fact, they were so large,
they had to be pulled by horses
178
00:11:39,833 --> 00:11:41,800
to get from building
to building.
179
00:11:45,872 --> 00:11:47,972
Through the magic
of suctioning power,
180
00:11:47,974 --> 00:11:52,210
a vacuum cleaner can make
dirt disappear almost instantly,
181
00:11:52,212 --> 00:11:54,979
really improving personal space.
182
00:11:55,916 --> 00:11:58,316
Production starts with
the electric motor
183
00:11:58,318 --> 00:12:00,585
that powers the suctioning fan.
184
00:12:03,924 --> 00:12:05,757
A machine picks up a rotor
185
00:12:05,759 --> 00:12:08,493
and transfers it
to an imaging system.
186
00:12:11,965 --> 00:12:15,600
Using a camera and laser,
the machine measures the part
187
00:12:15,602 --> 00:12:18,436
and confirms
that it's to specification.
188
00:12:21,942 --> 00:12:25,944
Next, an automated system
attaches plastic discs
189
00:12:25,946 --> 00:12:27,979
on to both sides of the part.
190
00:12:27,981 --> 00:12:32,517
These plastic discs will serve
as electrical insulators.
191
00:12:33,987 --> 00:12:36,821
A computerized camera
confirms the discs
192
00:12:36,823 --> 00:12:38,690
have been correctly placed.
193
00:12:40,894 --> 00:12:44,863
A carrier transfers the rotor
to the next station.
194
00:12:44,865 --> 00:12:49,067
Here, a rotary copper switch
is placed on to the shaft.
195
00:12:52,205 --> 00:12:54,806
The switch is called
a commutator.
196
00:12:54,808 --> 00:12:58,276
Its role is to periodically
reverse the electrical current
197
00:12:58,278 --> 00:13:00,512
as it flows through the motor,
198
00:13:00,514 --> 00:13:03,648
allowing the motor to operate
more efficiently.
199
00:13:03,650 --> 00:13:07,185
The next robot places the rotor
in a device that winds
200
00:13:07,187 --> 00:13:11,156
thin copper wire around
the part hundreds of times.
201
00:13:15,929 --> 00:13:18,496
These windings will be used
to create a rotating
202
00:13:18,498 --> 00:13:20,765
magnetic field in the motor.
203
00:13:23,970 --> 00:13:27,338
A welder joins the commutator
to the copper windings
204
00:13:27,340 --> 00:13:29,174
using small hooks.
205
00:13:33,513 --> 00:13:36,014
This step establishes
a connection.
206
00:13:40,887 --> 00:13:45,557
A machine slides a slatted
plastic cover over the rotor.
207
00:13:46,893 --> 00:13:49,394
The slats fit
in the rotor grooves.
208
00:13:51,932 --> 00:13:55,533
The cover reduces the noise
the rotor makes as it revolves
209
00:13:55,535 --> 00:13:57,268
at high speeds.
210
00:14:00,874 --> 00:14:05,043
Spouts drip synthetic resin
on to the copper windings.
211
00:14:05,045 --> 00:14:08,546
As it hardens, the resin
stabilizes the windings,
212
00:14:08,548 --> 00:14:11,082
ensuring there
are no loose wires.
213
00:14:14,020 --> 00:14:17,021
A computerized cutting tool
shaves off a small amount
214
00:14:17,023 --> 00:14:20,291
of the commutator,
making it round and smooth.
215
00:14:23,997 --> 00:14:28,333
A robot then deposits the rotor
on looped belts.
216
00:14:28,335 --> 00:14:29,934
The belts spin the rotor,
217
00:14:29,936 --> 00:14:34,839
and sensors detect vibrations
that indicate any imbalance.
218
00:14:34,841 --> 00:14:38,343
If an imbalance is found,
the system sends the rotor over
219
00:14:38,345 --> 00:14:42,947
to a tool that removes material
until the part is balanced.
220
00:14:45,919 --> 00:14:48,386
Then it's over to another
testing machine.
221
00:14:48,388 --> 00:14:51,890
This one probes the copper
windings to detect failures
222
00:14:51,892 --> 00:14:54,392
using a complex
measuring system.
223
00:14:56,863 --> 00:15:00,031
A mechanized system installs
a substantial bearing
224
00:15:00,033 --> 00:15:02,367
on one end of the shaft.
225
00:15:02,369 --> 00:15:04,702
A robot retrieves it, flips it,
226
00:15:04,704 --> 00:15:08,907
and the system attaches
a bearing to the other end.
227
00:15:08,909 --> 00:15:12,577
The motor housing with
the stator moves into position.
228
00:15:12,579 --> 00:15:17,181
A machine places the rotor
in the center of the stator.
229
00:15:17,183 --> 00:15:19,317
All the work on this
vacuum cleaner motor
230
00:15:19,319 --> 00:15:21,786
has been done by machines.
231
00:15:21,788 --> 00:15:24,789
Now a technician installs
a carbon brush
232
00:15:24,791 --> 00:15:28,559
that will make electrical
contact with the rotor.
233
00:15:28,561 --> 00:15:31,329
A diffuser shield is placed
on the housing.
234
00:15:34,968 --> 00:15:38,136
Meanwhile, the computer system
screws the diffuser
235
00:15:38,138 --> 00:15:39,871
to the motor assembly.
236
00:15:41,908 --> 00:15:44,208
A small metal spacer
is deposited
237
00:15:44,210 --> 00:15:47,912
on the protruding rotor shaft.
238
00:15:47,914 --> 00:15:51,215
A robotic arm places
the lower fan impeller plate
239
00:15:51,217 --> 00:15:53,117
over the shaft.
240
00:15:53,119 --> 00:15:56,387
The mechanized system screws
the assembly together,
241
00:15:56,389 --> 00:15:58,256
and then the upper part
is installed
242
00:15:58,258 --> 00:16:01,159
with the suctioning fan blades.
243
00:16:01,962 --> 00:16:06,798
A machine spins the fan
to test it for any imbalances.
244
00:16:06,800 --> 00:16:09,267
Then a cutting tool
removes material
245
00:16:09,269 --> 00:16:11,436
to calibrate the fan assembly.
246
00:16:14,040 --> 00:16:17,308
A steel cover is flipped
into position by a platform
247
00:16:17,310 --> 00:16:20,078
which elevates
the fan and motor assembly.
248
00:16:22,983 --> 00:16:24,482
Stay tuned.
249
00:16:24,484 --> 00:16:27,018
There's more dirt on how
the rest of the vacuum cleaner
250
00:16:27,020 --> 00:16:28,820
comes together.
251
00:16:43,570 --> 00:16:46,537
narrator: While the vacuum
cleaner may alarm your pet,
252
00:16:46,539 --> 00:16:51,009
to an enthusiastic cleaner,
this is an awesome machine.
253
00:16:51,011 --> 00:16:53,978
Not only does it remove
the dirt you can see,
254
00:16:53,980 --> 00:16:57,148
it suctions up fine particles
that aren't visible,
255
00:16:57,150 --> 00:17:00,118
leaving your home
even cleaner than it looks.
256
00:17:04,124 --> 00:17:05,990
Inside every vacuum cleaner,
257
00:17:05,992 --> 00:17:10,294
there's a high-speed
suctioning fan.
258
00:17:10,296 --> 00:17:13,431
Machines test the fan
for quality control.
259
00:17:16,202 --> 00:17:20,838
A conveyor delivers the fan to
a completely mechanized system
260
00:17:20,840 --> 00:17:22,440
that evaluates the interaction
261
00:17:22,442 --> 00:17:25,376
between the carbon brush
and the rotor.
262
00:17:27,480 --> 00:17:30,148
This final inspection ensures
the vacuum fan
263
00:17:30,150 --> 00:17:33,151
is balanced
and fully operational.
264
00:17:39,559 --> 00:17:41,592
a technician applies
a rubber seal
265
00:17:41,594 --> 00:17:44,429
to the rim of the vacuum's
lower housing.
266
00:17:44,431 --> 00:17:50,034
He inserts the power-supply reel
in a hollowed-out compartment.
267
00:17:50,036 --> 00:17:51,469
The fan is installed
268
00:17:51,471 --> 00:17:55,807
and connected
to the power-supply reel.
269
00:17:55,809 --> 00:18:00,111
He snaps the back panel
to the lower housing.
270
00:18:00,113 --> 00:18:03,614
The power-supply cable
is plugged in for a later check.
271
00:18:05,919 --> 00:18:10,021
The next component assembled
is the control panel.
272
00:18:10,023 --> 00:18:13,591
A technician screws the control
panel to a mounting plate.
273
00:18:16,096 --> 00:18:19,864
A rubber bumper is placed along
the edge of the cover frame.
274
00:18:23,903 --> 00:18:28,172
The cover frame is then
transferred to the vacuum.
275
00:18:28,174 --> 00:18:30,541
A dust bag is attached
to a bracket
276
00:18:30,543 --> 00:18:33,945
that straddles the frame.
277
00:18:33,947 --> 00:18:37,315
At the next station,
a robotic system stabilizes
278
00:18:37,317 --> 00:18:41,285
the assembly and attaches
the frame to the housing.
279
00:18:44,991 --> 00:18:48,226
Then the vacuum cleaner
is released from the machine,
280
00:18:48,228 --> 00:18:51,963
and the carrier takes it forward
for an inspection.
281
00:18:51,965 --> 00:18:55,299
An inspector installs foot
switches for the power cord
282
00:18:55,301 --> 00:18:59,036
and for machine activation.
283
00:18:59,038 --> 00:19:01,639
He tucks a filter into its slot.
284
00:19:03,143 --> 00:19:06,410
The cover panel now arrives
via conveyor.
285
00:19:06,412 --> 00:19:10,314
The technician snaps it
into place on the cover frame.
286
00:19:10,316 --> 00:19:12,750
He installs a hinged
access panel,
287
00:19:12,752 --> 00:19:15,853
which houses the suction tools
until needed.
288
00:19:15,855 --> 00:19:18,256
This is the final step
to complete the assembly
289
00:19:18,258 --> 00:19:20,358
of this vacuum cleaner.
290
00:19:20,360 --> 00:19:23,027
Another kind of vacuum cleaner
uses easy-to-empty
291
00:19:23,029 --> 00:19:27,198
plastic canisters
for dirt collection.
292
00:19:27,200 --> 00:19:31,469
It uses a substantial filter
to separate dirt from the air.
293
00:19:34,274 --> 00:19:37,875
Suctioned air and dirt spin
within this canister.
294
00:19:37,877 --> 00:19:40,378
Larger dirt particles fall
to the bottom,
295
00:19:40,380 --> 00:19:43,614
while finer particles
become embedded in the filter.
296
00:19:45,084 --> 00:19:47,385
A technician installs
the filter canister
297
00:19:47,387 --> 00:19:49,720
in the vacuum-cleaner
housing and inserts
298
00:19:49,722 --> 00:19:52,590
a nozzle accessory in a slot.
299
00:19:54,027 --> 00:19:58,129
Down the line, another worker
installs a top plate.
300
00:19:59,065 --> 00:20:02,200
Next, a clear plastic
interceptor is installed,
301
00:20:02,202 --> 00:20:05,803
which collects
the majority of the dirt.
302
00:20:05,805 --> 00:20:07,939
The technician apples
a plastic bumper
303
00:20:07,941 --> 00:20:11,075
to the back of the vacuum.
304
00:20:11,077 --> 00:20:14,478
With the assembly complete,
this bagless vacuum cleaner
305
00:20:14,480 --> 00:20:16,881
heads towards
the inspection station.
306
00:20:18,718 --> 00:20:22,386
Both kinds of vacuum cleaners
undergo final testing.
307
00:20:23,089 --> 00:20:25,790
A robot plugs the opening
for the hose,
308
00:20:25,792 --> 00:20:29,627
turns the power on,
and tests every function
309
00:20:29,629 --> 00:20:32,230
while a computer
measures its performance.
310
00:20:35,001 --> 00:20:39,270
Cleared for retail,
the robot removes the hose.
311
00:20:39,973 --> 00:20:43,307
The vacuum cleaner heads
toward the packaging line.
312
00:20:43,309 --> 00:20:45,977
A robot lifts and carries
the vacuum cleaner,
313
00:20:45,979 --> 00:20:50,615
stopping above a vacuum cleaner
that's already on the conveyor.
314
00:20:50,617 --> 00:20:53,050
The vacuum on the conveyor
moves forward,
315
00:20:53,052 --> 00:20:57,688
and sensors signal the robot
to set the second vacuum down.
316
00:20:57,690 --> 00:21:00,524
The vacuum cleaner moves
along the conveyor belt
317
00:21:00,526 --> 00:21:04,562
into a sheet of plastic wrap,
which envelops the product.
318
00:21:06,466 --> 00:21:11,469
Heated knives cut and seal
the ends in one action.
319
00:21:11,471 --> 00:21:13,771
This protects it
from superficial scratches
320
00:21:13,773 --> 00:21:15,506
during transport.
321
00:21:16,876 --> 00:21:19,610
A technician uses
molded pieces of foam
322
00:21:19,612 --> 00:21:22,947
to slide the vacuum
into a cardboard box.
323
00:21:22,949 --> 00:21:25,082
The foam pieces remain
in the box
324
00:21:25,084 --> 00:21:28,519
to stabilize the vacuum
during transport.
325
00:21:30,023 --> 00:21:33,491
Equipped with either a bag
or a plastic receptacle,
326
00:21:33,493 --> 00:21:37,161
the technology is all up
to the consumer's preference.
327
00:21:37,163 --> 00:21:39,997
Regardless of the model,
each type of vacuum
328
00:21:39,999 --> 00:21:43,467
can make dust bunnies
stuck in the corners of rooms
329
00:21:43,469 --> 00:21:46,871
and under beds
vanish before your eyes.
