DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a method and apparatus for manufacturing adhesive-coated magnetic cards used for various cards such as telephone cards and 10 cards.

[Prior Art] Many magnetic cards of this type have been known in the past, but among these, the telephone card that allows calls to be made without the need for coins was released by Nippon Telegraph and Telephone Corporation in 1981. It has been widely used ever since. After that, Showa 5
In 1985, design cards were issued that individuals and companies could freely design, and the cards were used as souvenirs and product advertisements.Furthermore, in 1985, the White Telephone Car F, on which people could write their own messages, went on sale. There is.

This white telephone card can not only be used to write messages, but also to print your favorite designs on the card.
Alternatively, it has become particularly popular recently because it is possible to create original cards by pasting photographic paper.

However, the method of printing designs is very expensive, and the method of pasting photographic paper on the card has the disadvantage that the card itself becomes thicker and its functionality is impaired.

On the other hand, a method is known in which instant photographic film (hereinafter referred to as film) is washed with a water-based solvent to remove the emulsion on the back, cut into any shape, and then affixed to the surface of a white telephone card. It is being

[Problems to be Solved by the Invention] It is desirable that the white telephone card used in this method has an adhesive layer formed on its surface.However, in the past, this type of white telephone card was commercially available only as a card. Therefore, in order to make a telephone card using the above method, an adhesive layer had to be added at the manufacturing stage. For this reason, in the past, an adhesive was applied to the surface of the white telephone card or double-sided tape was attached to form an adhesive layer. However, all of these methods are complicated and require a lot of time and effort, so they have the disadvantage of poor workability.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus for manufacturing an adhesive-backed magnetic card, which solves the above-mentioned problems, has good workability, and can easily produce cards with originality.

[Means for Solving the Problems] The method for producing a magnetic card with an adhesive according to the first invention includes inserting a double-sided adhesive tape having a release film on at least one side and a magnetic card in a stacked manner between a pair of laminating rolls. The adhesive layer of the adhesive tape is brought into close contact with the surface of the magnetic card by conveying under pressure, and then the release film is cut to match the shape of the magnetic card to form an adhesive layer on the surface of the magnetic card. It is characterized by forming a release film.

The manufacturing apparatus of the second invention is an apparatus for carrying out the method of the first invention, which comprises a double-sided adhesive tape roll having a release film on at least one side, and a pair of laminating rolls rotating in the same direction in different directions. and at least one tension roll for tensioning the double-sided adhesive tape between the double-sided adhesive tape roll and the laminate roll.

[Function] When a double-sided adhesive tape is guided between rolls with the adhesive layer side facing outward, and a magnetic card is placed on the adhesive layer side with the magnetic side of the tape placed on the opposite side.

As the laminating roll rotates, the magnetic card and double-sided adhesive tape are conveyed under pressure and sent out. Since a magnetic card is bonded to a strip-shaped release film to form a card row, by cutting the release film to match the shape of the magnetic card, a magnetic card having an adhesive layer and a release film on the surface can be obtained. This Ij1'A card can be stored with a release film attached until it is used, and when used, the release film on the surface is peeled off.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. In the following embodiments, a method and apparatus for manufacturing a white card with an adhesive used for a telephone card will be explained as an example.

FIG. 1 is a block diagram of an adhesive-backed white telephone card manufacturing device. In FIG. They are configured to rotate in the same direction in different directions by a device (not shown). As the laminating roll 2, a rubber roll or the like having elasticity is used.
A predetermined pressure is applied between the rolls.

The double-sided adhesive tape roll l is set in a roll holder (not shown) provided at a portion of the pressure conveying means 7, and a tension roll 3a is arranged between it and the laminating roll 2 at the bottom. ing.

The double-sided adhesive tape roll l used in this example is
As shown in the figure, a light release film 1 is placed on both sides of the adhesive layer 12.

Next, the light release film 1 on the outside of the roll of double-sided tape
1 was peeled off and passed through the guide portions of the tension rolls 3b at three locations, and then inserted between the rolls from the upper laminating roll 2 side of the laminator 7. On the other hand, a tape having an adhesive layer 12 on one side is placed on the heavy release film 13 side.
After passing between the guides of the tension rolls 3a at several locations, the film was inserted between the rolls from the lower laminate roll 2 side of the laminator 7, and bonded to the light release film 11 again.

At this time, a heavy release film 13 having a light release film 11 and an adhesive 12 was stretched on all the tension rolls 3a and 3b.

Next, 50 white telephone cards 14 were stacked and set in the card holder 5 with the magnetic layer facing upward, and an iron weight was placed on top of the cards.

Next, in this state, the pasting machine was operated at a roll extrusion speed of 1.2 layers per minute and a card feeding speed of 12 sheets per minute.
Fifty cards were laminated with a 13.75c layer spacing.

At this time, the card is conveyed under pressure by rollers, so
No air bubbles were observed on the bonded surface of the white telephone card.

After bonding, the light release film 11 was peeled off and the periphery of the card was cut with a cutter to obtain an adhesive-attached white telephone card having the heavy release film 13 on the upper surface of the adhesive layer 12.

In this embodiment, since a double-sided tape having release films on both sides is used, the strip-shaped card row sent out from the laminator becomes as shown in FIG. 3, and the spaces between the cards are also covered. Therefore, the adhesive layer 12 is not exposed and subsequent handling becomes easy. However, the present invention can be used without any problem as long as it is a double-sided tape having a release film on at least one side.

Further, although an automatic card feeding device is used for feeding out the cards in the embodiment E, the feeding of the cards may be performed manually.

[Effects of the Invention] As explained above, according to the present invention, a magnetic card and a double-sided tape having a release film are stacked and inserted between a pair of laminating rolls, and the adhesive is formed by conveying the tape under pressure. It is possible to mass-produce magnetic cards in a short period of time, and work efficiency can be greatly improved. By simply peeling off the release film on one surface of the adhesive-coated magnetic card obtained in this way, it is possible to attach your favorite design or photographic film, making it easy to create magnetic cards such as original telephone cards. can do.
