DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-sided laminate in which a transparent film is laminated on one surface of a card-like or sheet-like laminate to protect or prevent tampering of the surface of the laminate, and a single-side laminate thereof. Things continuously,
The present invention relates to a manufacturing method and an apparatus for manufacturing with high efficiency.

[0002]

2. Description of the Related Art Conventionally, in order to prevent abrasion and staining of cards such as commuter passes, membership cards, color samples, maps, documents, calendars, timetables, posters, or sheet-like articles (laminated objects). Laminating a transparent film on the surface is performed, and there are two types of laminating, a double-sided laminating type and a single-sided laminating type.

[0003] In the case of double-sided lamination, a method of laminating one piece at a time is a method in which a transparent thermoplastic plastic film called a pouch is folded in two and an object to be laminated is sandwiched, and both sides are laminated using a heat laminator. Is commonly practiced.

In order to efficiently and continuously process a large number of objects to be laminated, a heat laminator method and a cold laminator method using a roll film are known.

[0005] On the other hand, in the case of single-sided lamination, usually, a laminated film is laminated on an object to be laminated in a leaf form and adhered by a heat laminator or a cold laminator. Has not been adopted.

For example, when a single-sided heat laminator system is applied and a continuous laminating process is performed, an object to be laminated tends to be displaced with respect to a roll film, and when a thermoplastic plastic surface comes into contact with a heat roll,
There is a problem of fouling the heat roll. Further, when a single-sided laminating process is performed by using a cold laminator as shown in FIG. 3 as a single-sided cold laminator method, there is a disadvantage that the processing cost is increased.

More specifically, the single-sided cold laminator shown in FIG. 3 is a single-sided cold laminator in which an object 1 to be laminated is placed between an upper roll film 12 with release paper 15 and a lower auxiliary roll film 13 having no adhesive property.
(Hereinafter referred to as a work), the upper roll film 12 is adhered to the work 1 by nip rolls 3 and 4, discharged by a pull roll 10, cut by a cutter 9, and laminated on one side. There is a problem that the roll film 13 becomes waste and is uneconomical.
In the drawing, 14 is a release paper take-up roll, and 16 and 17 are guide rolls.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method and apparatus for producing a roll film type single-sided laminate which enables continuous, high-efficiency, low-cost lamination at one side, and a tactile discrimination function for front and rear. It is an object of the present invention to provide a single-sided laminate having abrasion resistance and crack resistance of side edges.

[0009]

Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and the first feature is that a thermoplastic film of a roll film type laminated film preceding a work (substrate to be laminated) is provided. After the surface is bent to the back side of the work, the work is passed through a heating / pressing roll. As a result, the work is positioned on the laminate film, and the leading edge is gripped by the bent portion of the laminate film, thereby preventing the occurrence of displacement when the heating / pressing roll enters and the roll film method can be adopted. is there.

In the case of a single-sided laminate manufactured by the manufacturing method of the present invention, a step is formed at the front edge of the card due to a folded portion (bent portion).
Since there is a function of discriminating front and rear by tactile sensation, it is possible to provide one having a function similar to a cutout found in a telephone card.

Also, since the leading edge of the object to be laminated is covered and protected by the folded portion of the laminated film, a single-sided laminated card having abrasion resistance can be provided. When the present invention is applied to a commuter pass which must be provided, it is possible to provide a ticket which has a good biting effect and an effect of eliminating the occurrence of trouble, in combination with the slightly thicker leading edge.

Further, since the sheet-like single-sided laminate according to the present invention has a structure in which one side edge is reinforced, it is possible to provide a sheet which does not easily crack when a spelling hole is provided.

Further, the present invention will be described in detail. According to a first aspect of the present invention, one side edge of a thermoplastic film which produces adhesiveness by heating is folded back to an appropriate width, and is folded into a card or sheet-like laminate. A single-sided laminate characterized by being stacked on an object and one side edge of the object to be laminated is inserted into the folded portion of the thermoplastic film and heat-laminated. In the case of mass production, the production method according to the second invention described below is excellent, but it can also be produced one by one.

According to a second aspect of the present invention, a card or sheet-like material to be laminated is superimposed on an adhesive side surface of a roll-like thermoplastic film which generates adhesiveness by heating, and is sent in the direction of a heating / pressing roll by a guide roll. After folding the leading edge of the film to the side of the object to be laminated along the leading edge of the object to be laminated, the thermoplastic film is heat-laminated on the object to be laminated by passing through the heating / pressing roll. It is a manufacturing method of. According to this manufacturing method, continuous, high-efficiency, low-cost production of a single-sided laminate by a roll film method becomes possible.

A third aspect of the present invention relates to a single-sided laminating apparatus to which the second aspect of the present invention is applied, in which guide rolls, cutters, restraining means, bending means, and heating / pressing rolls are sequentially arranged, and the guide rolls are heated by heating. The object to be laminated is superimposed on a roll-shaped thermoplastic film that gives rise to adhesiveness, and then sent. Then, while the thermoplastic film and the object to be laminated are suppressed by the suppression means, the leading edge of the thermoplastic film is bent by the bending means. After folding an appropriate width along the leading edge of the object to be laminated to the object to be laminated,
A single-sided laminating apparatus characterized in that the thermoplastic film is heat-laminated by the heating / pressing roll and the rear part of the thermoplastic film is cut along the rear edge of the laminated object by the cutter. Single-sided laminates can be manufactured continuously, with high efficiency and at low cost.
