Description

Description: TECHNICAL FIELD The present invention relates to a method for processing a pseudo-adhesive sheet used for attaching a concealing member to a postcard or the like in a releasable manner, and particularly to a method for processing an end portion thereof. .

[Conventional technology]

Recently, when a financial institution or the like notifies various kinds of information for personal use, postcards and the like in which this personal information is hidden by a concealing member have been sent, and the recipient side has to peel off the concealing member. Information can now be confirmed. As shown in FIG. 6, a postcard used for this type of notification uses a format in which a concealing member b is adhered to a base material a with a pseudo adhesive sheet 1 interposed therebetween, and the concealing member b is peeled off. By taking this, the pseudo adhesive sheet is divided into upper and lower layers, and provided so that information can be confirmed through the sheet remaining on the base material side.

As shown in FIG. 7, the pseudo-adhesive sheet 1 is a pseudo-adhered first transparent film 2 and a second transparent film 3 (a synthetic resin film such as polyethylene, polyester, etc.) The film is, for example, materials having different melting temperatures). A first release paper 6 is attached to one surface of the sheet 4 on the base material side of the sheet 4 via the adhesive 5 while the other surface of the sheet 4 on the concealing member side is Adhesive 7 in the same way
And has a layered structure in which a second release paper 8 is adhered through. Then, the upper and lower release papers 6 and 8 are peeled off, and the concealing member b is adhered to the base material a through this (see FIG. 8). Then, the concealing member b is peeled off from the joint surface of the two transparent films 2 and 3 that have been pseudo-adhered by the stripping operation of the concealing member b, so that the concealing member b can be removed.

[Problems to be solved by the invention]

By the way, in the postcard or the like using the above-described pseudo adhesive sheet, as shown in FIG. 8, since the edges are aligned, there is no finger catch, and it is difficult to form a peeled edge when peeling off the concealing member. There is a point. Therefore, in the state of having the release paper, for example, a slit is formed along the end of the sheet 1 so as to reach the first transparent film 2 from the release paper 6 on the base material a side, and the other second It is conceivable to expose the end of the transparent film 3 and to peel off the transparent films 2 and 3 using the exposed end as a fingerhold (see FIG. 9).

However, if the width of the exposed portion 9 is increased, the concealing member is easily peeled off in the process of sending a postcard or the like, so the width of the exposed portion 9 must be about 1 mm. on the other hand,
When removing the transparent film and release paper after slitting, continuous winding (scuffing) is performed, so surplus members with a width of about 1 mm are easy to cut, and it is possible to reliably remove from the sheet 1 There is a problem that can not be.

Therefore, an object of the present invention is to form a finger hook that does not cause peeling at the time of sending, and to reliably remove a surplus portion, and an object of the present invention to efficiently manufacture a pseudo adhesive sheet.

[Means for solving the problem]

The present invention has been made in view of the above problems,
For a pseudo-adhesive sheet having a layer structure in which a release paper is releasably adhered to the upper and lower sheets of a pseudo-adhesive two transparent film via an adhesive, along the edge of the pseudo-adhesive sheet, A slitting step of putting a slit from the release paper to reach one of the transparent films to which the release paper is pasted via an adhesive, and peeling one of the transparent films separated by the slit onto the other. A separation process to remove from the end of the pseudo adhesive sheet together with the paper,
On the other transparent film corresponding to the portion to be removed by the separation step and the other release paper stuck on the other, to the finish cutting position set slightly outside the slit perforation position of the slit step The above-mentioned problem is solved by performing an end treatment including a finishing slit step of forming a slit.

(Operation)

In the present invention, the other transparent film and release paper corresponding to the portion to be removed by the slit in the slit step,
Only by inserting a slit along the finishing position, the other transparent film and the surplus portion of the release paper can be separated, and the surplus portion is automatically removed.

〔Example〕

Next, the present invention will be described in detail based on the embodiment shown in FIGS.

In the present invention, as shown in FIG. 1, the pseudo adhesive sheet 1 whose width dimension is larger than the finished width before the end processing is unwound from a roll state, and this is unrolled into a first slitter 10 and a second slitter 11. , And the finished width is taken up again in a roll state.
Then, the sheet 1 having a finished width is obtained by processing one end of the sheet 1 through the second slitter 11.

In the slitter 10, a slitting step is performed.
In this step, as shown in FIGS. 2 and 3, the first release paper 6 on the side of the base material, for example,
Then, a slit 12 is formed so that the release paper 6 reaches the first transparent film 2 adhered via the adhesive 5. The perforated portion of the slit 12 is set at a fixed distance from the other end of the sheet 1 so that the width of the exposed portion 9 becomes 1 mm by a finishing slit process described later. That is, it is determined by the finishing width of the sheet 1.

After passing through the slitter 10, the separation process is performed and the slit
The end of the first transparent film 2 and the end of the first release paper 6 divided by 12 are scraped off by the take-up roller 13. At this time, the winding width is a width that cannot be cut. (See FIGS. 2 and 4).

Thereafter, a finishing slit process is performed in the slitter 11. This finishing slit process is performed at the exposed part 10,
The slitter 11 forms a slit at a finishing cutting position 14 set to be 1 mm outward from the slit 12, and the surplus portion is automatically dropped and separated by its own weight by inserting the slit (FIG. 2). And the fifth
See figure).

After the sheet 1 having a finished width is obtained and rolled up by this end processing, the sheet 1 is pulled out from this roll, one release paper is removed, and the sheet 1 is used by being interposed between the base sheet and the concealing member sheet. Is done.

In the above embodiment, the slitting step, the separating step, and the finishing slitting step are sequentially performed. However, the present invention is not limited to this, and the order may be changed.

[Effects of the Invention] As described above, according to the present invention, a pseudo layer having a layer configuration in which release paper is releasably adhered to the upper and lower sides of a sheet composed of two pseudo-bonded transparent films via an adhesive. For the adhesive sheet, along the edge of the pseudo adhesive sheet,
A slitting step of putting a slit so that the release paper reaches one transparent film to which the release paper is adhered via an adhesive from one release paper, and one transparent film divided by the slit is adhered to this. Along with the release paper, a separation step of removing from the end of the pseudo-adhesive sheet, and the other transparent film corresponding to the portion to be removed in the separation step and the other release paper adhered thereto are subjected to slit punching in the slit step. A finishing slitting step of inserting a slit at a finishing cutting position set slightly outward from the installation position, so that a part to be removed from the side where a finger hook is formed is removed by its own weight or It is automatically separated by being rolled up by scraping in the separation process, so that the exposed part, that is, the finger hook part, can be provided with a short width. With wear, sheet can be produced efficiently, in which more such inadvertent separation of the concealment member will be able to prevent, exhibits an extremely excellent effect on postcards with a concealing member.
