Description

Method for producing clear file {Method for producing clear file}

The present invention relates to a method for producing a clear file having a transparent pocket for storing various documents or data, and more particularly, to a clear file having a pocket on one or both sides thereof, with the center of the transparent cover fixed to the inner center of the cover. It relates to a manufacturing method.

In the related art, as shown in FIGS. 5 and 6, the target transparent synthetic resin film 50 has a predetermined length to form a fusion portion 52 on the lower side and cut the outer side of the fusion portion 52. To make 56 with pockets 54, insert two inlays 58, 58 'of opaque paper into the pocket 54 of 56 and then file cover 60 Four pockets 54-1 and 54-2 in one to 56 as shown in FIGS. 7 and 8 by fixing the center of the to 56 to the inner center of ), (54-3) and (54-4) have been prepared.

Such a conventional manufacturing method has mainly relied on the insertion of the inlays 58 and 58 'by manual operation because the automation equipment for inserting the inlays 58 and 58' is very expensive and the operation reliability is insufficient.

Thus, in the past, productivity was low and manufacturing cost was increased.

Inlays 58, 58 'are placed at the central portion of the to 56 to be fused with the file cover 60 when the inlays 58, 58' are manually inserted into the pocket 54. Care should be taken to avoid inserting the inlay (58), (58 ') itself into the contaminant pocket (54) contaminated with foreign matter during operation, or the inlay (58), (58') into the pocket (54). There is a problem such as being inserted with a) causing a defect of the product.

And since the inlays 58 and 58 'were simply inserted into the pocket 54, the inlays 58 and 58' moved easily when the various documents or materials were put into or removed from the pocket 54. There was a problem such as being injured or easily detached from being built, unable to function as an inlay dividing pocket.

The present invention is composed of one sheet of opaque synthetic resin film and two sheets of transparent synthetic resin film each of which is folded in two layers, and the inlay and the sheet of two transparent synthetic resin films that are fixed on the lower side and each other It is a technical object of the present invention to provide a method for manufacturing a clear file having pockets which are separated by abutting free ends fixed to an inner center of the file cover.

When explaining the present invention in detail step by step as follows.

First step;

As illustrated in FIG. 1, the transparent synthetic resin films 10 and 14 folded in two layers in a state where the inlay transparent synthetic resin film 10 is intermittently fed, are separated from the opaque synthetic resin film 10. Supply from both sides.

In this case, the transparent synthetic resin film 12 and the transparent synthetic resin film 14 surround the table and the back surface of the opaque synthetic resin film 10, and the free end 16 of the transparent synthetic resin film 12 and the other transparent synthetic resin film 14. The free end 18 of) is to face each other on the center line of the opaque synthetic resin film (10).

Second step;

The opaque synthetic resin film 10 and the lower side of the transparent synthetic resin films 12 and 14 surrounding the opaque synthetic resin film 10 are bonded by the first heat-sealed portion 20.

Third step;

The opaque synthetic resin film 10 and the transparent synthetic resin films 12 and 14 bonded to the lower side by the first heat-sealed portion 20 are moved together at a predetermined distance.

Fourth step;

(B) is manufactured by cutting the outer side of the first heat-sealed portion 20 formed in the second step.

Fifth step;

The (B) prepared in the fourth step is laminated to the inside of the pile outer cover 22 by an appropriate number as illustrated in FIG. 2, and then the transparent synthetic resin film 12 facing each other on the centerline of the (B). The free ends 16 and the free ends 18 of the transparent synthetic resin film 14 are joined together to the second heat-sealed portion 24 on the inner center line of the pile cover 22 to form (B). It is fixed to the inside of the front cover (22).

The clear file manufactured by the present invention has a lower side of the inlay (A) made of an opaque synthetic resin film 10 as shown in FIGS. 3 and 4, and the transparent synthetic resin films 12 and 14 folded in two layers. (B) is a transparent synthetic resin film 12, (14) bonded to the lower side and the first heat-sealed portion 20, and folded in two layers with the central portion of the inlay (A) made of an opaque synthetic resin film (10). Four pockets C1, C2, C3, C4, which are separated by joining the free end portions 16, 18 of the pile cover 22 to the pile cover 22 with the second heat-sealed portion 24. ) To (B).

The present invention as described above is a step of supplying, bonding, and cutting the two-folded transparent synthetic resin film 12, 14 forming the (B) to the intermittently feeding the opaque synthetic resin film 10 forming the inlay (A) It is possible to automate the manufacturing process, so that mass production of clear files with uniform quality at a lower cost than in the past, where two inlays of opaque paper were inserted into the pockets by manual labor Suitable for

According to the present invention, the inlay (A) is firmly bonded in the (B) to the high-quality clear file without the risk of being damaged or detached when the inlay (A) is put or removed in the pocket at a lower cost There are advantages such as mass production.
