Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a card having a concave portion for embedding a photograph, a seal verification field, etc. on the surface of the card.

It has been proposed that cards such as credit cards and ID cards be provided with a face photo, seal verification column, etc., in order to identify the owner and prevent unauthorized use by people other than the owner. There is.

Although such a means of identifying the owner of a card is a fairly effective means for achieving that purpose, if a face photograph or a stamp verification field are pasted directly on the flat surface of the card, the thickness of the information cannot be ignored. Due to the fact that the adhesive is attached to the adhesive, that part protrudes from the surrounding area, resulting in the problem that the adhesive may peel off or be damaged.

In order to solve this problem, a method is currently available in which a recess is provided on the surface of the card and a face photograph, a seal verification column, etc. are buried in the recess.

3- Methods for forming recesses on the surface of the card are as follows:
A method in which a card is manufactured using a normal process, and then a part of the surface is cut with a milling machine to form a recess.

■A release layer is provided between the center core and oversheet,
A method of cutting along the periphery of the release layer after lamination or half-cutting it to form a recess.

Two methods are widely known.

However, the first method requires processing one sheet at a time, which requires a long time and effort to manufacture, and has the drawback of poor production efficiency (and unsuitability for mass production).

In addition, in the second method, a step of providing a release layer during the manufacturing process and a step of removing the oversheet from the release layer are added, which increases the number of manufacturing steps and reduces production efficiency. It is necessary to prepare a release agent for forming the layer as a card constituent material, which has the disadvantage of high cost.

Therefore, an object of the present invention is to eliminate the drawbacks of the above-mentioned prior art, and to avoid increasing the time and cost required for production by forming recesses (forming recesses easily and accurately on the card surface). The goal is to provide a way to do so.

The present invention will be explained in detail below based on embodiments of the drawings.

In manufacturing cards, a common method is to apply so-called multi-sided printing to a sheet with large dimensions, and after finishing processes such as printing and gluing, the card is manufactured by finally cutting it to a predetermined size. In all explanations, the above multi-page printing method will be used as an example, but the method is not limited to this, and the sheets constituting the card can be finished in advance to the same dimensions as the final product, and the sheets can be printed on a single sheet, glued, etc. It is also applicable to the method of manufacturing cards.

In FIG. 1, fi+ (2) is an oversheet made of a thermoplastic synthetic resin sheet, for example, a transparent polyvinyl chloride sheet can be used.

Further, (3) and (4) are thermoplastic synthetic resin sheets to serve as the center core, and are made of, for example, an opaque bone-white polyvinyl chloride sheet.

The surface of the oversheet 111 side of the center core sheet (3) and the surface of the oversheet (2) of the In this embodiment, 9 impositions) are printed.

Such an oversheet ti+ and a center core sheet (3), or an oversheet (2) and a center core sheet (+41) are bonded together by heat fusion, adhesive, etc., and the laminated sheet and eggplant form an oversheet in which no holes are formed. (2) and the center core seam die 4) do not necessarily need to be glued together.

In this example, the number of stacked center core sheets is 2.
The layer may be six layers or more, and in that case, the number of center core sheets to be included in the laminated sheet in which holes are formed may be arbitrary, but preferably as described below. Since the thickness of the laminated sheet corresponds to the depth of the recesses finally obtained, it is preferable to determine the number of recesses so as to obtain the desired depth of the recesses, that is, the thickness of the laminated sheet.

The laminated sheet (5) consisting of the Oversea 1111 and the center core sheet (3) is then laminated with a size and shape corresponding to the facial photograph to be embedded in register with the printed information formed on the surface of the center core (310). Hole (6), (6)
, . . . (nine holes in this embodiment) are drilled. In order to make holes +61- +61, . . . in the laminated sheet +51, the sheet may be punched out using a blade having a predetermined positional relationship and shape.

The thus obtained laminated sheet (5), oversheet (2), and center core sheet +41 are stacked so that the center cores are in contact with each other, and two opposing sides KG are provided with through holes for positioning. After drilling with a drilling machine or the like, attach the crimp plate (generally called Ferro plate) (21+) shown in Fig. 2.

The pressure bonding plate (211 is a structure in which two plates f23+, (23+) are rotatably connected by a hinge (26), and here, the pressure plate (23+) is connected to the pressure plate (23+) of the laminated sheet (5). Convex portions (2η, (2
n, . . . are provided protrudingly. In addition, board (231
is provided with positioning protrusions (24, (24+, . . . ,..., into the positioning hole (25+-(
251, . . . are provided.

The height of the convex portion (27) is the same as or slightly smaller than the thickness of the laminated sheet, and its cross-sectional shape is similar to the cross-sectional shape of the hole (6), so that it fits into the hole (6) with almost no gaps. It is preferable to have a shape that fits together.

A group of sheets stacked one on top of the plate (23) of the crimping plate 1) is inserted into the through hole for positioning with the protrusion (24), (
Hole (4), t4) while positioning by inserting stop 2 and 4,
Attach the convex part (271, (tough,...) to ...... by fitting it together.

After that, it is rotated around the plate (the second part is hinge 06) and brought into close contact with the sheet group attached to the plate.

The sheet group is held between the plates (23). At this time, the positioning protrusions (24L (24h')... are fitted into the positioning holes (25+, (251,...) for positioning.

In this state, as shown in FIG. 6, the heat suppression members (281 to CI!91
moves from the top and bottom toward the pressure bonding plate (211 plate (2), (231), clamps the pressure bonding plate with a constant pressure, and heats it. As a result, the laminated sheet (5) and the oversheet (2
) and the center core sheet (4) are heat and pressure applied from the pressure bonding plate (21).
1 (271 = ...) is inserted, so the holes (6), (6), ...... may be deformed or blocked due to the heat and pressure. There is no need to worry.

After heating and pressurizing for a predetermined period of time, heat suppressing members (z8) and (2
9) from the crimp plate (21+), then remove the plate (22).
is rotated and released, and the integrated sheet is removed from the pressure bonding plate 12D.

This creates a card with four parts (31) on the front.
By setting this sheet in a punching machine and punching it out into a card shape, a card (31
) can be created.

A facial photograph is created by embedding a face photograph, a seal verification field, etc. in the concave part of the card created in this way, and pasting a transparent protective layer only on that part.

It is possible to complete a card having a seal verification column and the like.

The structure of the devices such as the pressure bonding plate and the heating valve pressure member shown in this explanation is merely an example for carrying out this invention, and various modifications may be made without departing from the gist of this invention. can be changed.

The present invention is as described above, and it is possible to manufacture cards with recesses on the surface, which conventionally required very complicated work, without adding special processes such as cutting, to the production of general cards. Since it can be carried out in substantially the same steps as the above process, it not only simplifies manufacturing and shortens manufacturing time, but also has excellent effects such as being suitable for actual production in terms of equipment.

Also, regarding the depth of the recess, the thickness of the oversort should not be the same as the depth of the recess. By adjusting the thickness of the center core sheet that is bonded to the sheet, the depth of the recess can be set to a desired value, and the recess can be easily manufactured to a depth that corresponds to the thickness of the buried object.

Furthermore, the shape of the concave portion does not tend to deform into a T shape, which is a heating and pressure countermeasure, and is an extremely excellent method that takes into consideration the quality of the card.
