00:00:27.780 --> 00:00:29.180
In

2
00:00:29.180 --> 00:00:34.300
Carroll Stream, Illinois, Container Corporation of America operates the largest best equipped

3
00:00:34.300 --> 00:00:40.620
packaging complex in the United States. Among the highly specialized staff services headquartered

4
00:00:40.620 --> 00:00:50.780
in the container division's portion of the complex is mechanical packaging. The emphasis

5
00:00:50.780 --> 00:00:56.340
in the mechanical packaging department is on improving overall packaging line performance

6
00:00:56.340 --> 00:01:01.740
rather than promoting the application of a particular machine or line of machines.

7
00:01:03.420 --> 00:01:08.740
CCA mechanical packaging engineers always counsel their customers to consider the special

8
00:01:08.740 --> 00:01:13.860
requirements of their own situation rather than the possibilities offered by available

9
00:01:13.860 --> 00:01:20.220
existing equipment. Think first, they will tell you, of your packaging needs and the

10
00:01:21.520 --> 00:01:28.200
have. We can adapt our equipment to your needs in many cases and if your needs require it,

11
00:01:28.440 --> 00:01:34.620
we will then design special equipment to meet those needs. The Concora wrap is a case in

12
00:01:34.620 --> 00:01:40.580
point. The machine itself is only part of the equation. The wrap pack blank is another

13
00:01:43.060 --> 00:01:51.660
and how they work together is still another. This special CCA combination, the Concora wrap

14
00:01:51.660 --> 00:01:58.040
machine and the wrap pack blank was designed quite literally to form a package around its

15
00:01:58.040 --> 00:02:10.560
contents and the contents can vary across a wide range of products, arrangements and sizes. In

16
00:02:10.560 --> 00:02:16.920
individual cartons are conveyed to the accumulator where they are arranged into units of 12 cartons,

17
00:02:17.120 --> 00:02:24.440
3 wide and 4 high. Vacuum cups pull the bottom wrap pack blank from the supply hopper bringing

18
00:02:24.440 --> 00:02:27.900
it into an L shape as it is positioned in front of the sheet feeder.

19
00:02:45.700 --> 00:02:50.140
Adhesive is applied to the underside of the trailing vertical panel as the sheet

20
00:02:50.140 --> 00:02:58.580
is fed into the wraparound section of the machine. With the blank in position,

21
00:02:59.180 --> 00:03:04.740
the accumulated product is loaded onto it by the action of a ram. This action starts

22
00:03:04.740 --> 00:03:25.620
the Concora wrap machine cycle. Subsequent actions in the main part of the machine complete the

23
00:03:25.620 --> 00:03:32.300
folding of the wrap pack blank around the product. As panels and inner flaps are positioned,

24
00:03:32.300 --> 00:03:38.280
the wrap pack blank becomes a strong box snugly fitted around the product.

25
00:03:47.780 --> 00:03:52.620
As the box continues on its course through the machine, adhesive is applied to the outer

26
00:03:52.620 --> 00:03:58.280
flaps and these are plowed closed just before the completed box moves into the vertical compression

27
00:03:58.280 --> 00:04:21.440
section. As the box is lifted vertically, a final action of the machine folds the

28
00:04:22.180 --> 00:04:29.360
joint flap down over the vertical panel. Now the end-to-end side-to-side pressure of the

29
00:04:29.360 --> 00:04:34.800
spring-loaded compression belts keeps pressure against all glue lines long enough to secure

30
00:04:34.800 --> 00:04:42.760
closure. At the top of the compression section, boxes move out onto the customers' conveyor lines.

31
00:04:45.300 --> 00:04:52.280
Again, we emphasize that this is a customized, not a standard installation. Other applications

32
00:04:52.280 --> 00:04:57.260
of the Concora wrap machine and the wrap pack blank combination have included the packaging

33
00:04:57.260 --> 00:05:04.480
of such widely varying items as gallon cans of paint and diesel engine cylinder kits. The

34
00:05:04.480 --> 00:05:11.440
latter application involved a further, more complex adaptation of the principle. The

35
00:05:11.440 --> 00:05:17.460
wrap pack cylinder kits were subsequently combined into six kit units around which

36
00:05:17.460 --> 00:05:23.340
larger wrap pack blanks were formed into master shipping containers, thereby maximizing product

37
00:05:23.340 --> 00:05:31.800
protection. The flexibility of wrap pack permits many useful options, including partial or complete

38
00:05:31.800 --> 00:05:37.360
automation of the packaging lines involved. Other advantages include economy in both the

39
00:05:37.660 --> 00:05:43.840
material used in the blank and in the floor space needed for the machine. Best of all,

40
00:05:44.200 --> 00:05:50.100
every Concora wrap installation carries the full service feature which is the heart of CCA mechanical

41
00:05:50.100 --> 00:05:57.520
packaging. To summarize further, the Mechanical Packaging Department of Container Corporation

42
00:05:57.520 --> 00:06:03.900
of America is interested in making problem-solving recommendations based on an evaluation of your

43
00:06:03.900 --> 00:06:11.220
particular needs. Our goal is really the same as yours, to achieve packaging line performance on

44
00:06:12.060 --> 00:06:13.740
your packaging line.
