Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a postcard in which a postcard is integrally attached to the back surface of a paper on which an image is formed, and an apparatus for improving the method. Belongs to the technical field of attaching using an adhesive.

[0002]

2. Description of the Related Art The conventional method for attaching a postcard to a paper on which an image has been formed is the most common method for making postcards by using an adhesive on the back surface of the paper on which the image is formed. There is a method of sticking with a liquid adhesive such as a water-based adhesive and a method of sticking with a double-sided adhesive tape.

[0003]

Among these pasting methods, in the former method and apparatus for making a postcard using a liquid adhesive, since an adhesive having an irregular shape and adhesive strength is used, it is applied to the back surface of the paper. In the process, the adhesive sticks easily and is difficult to handle.In addition, the adhesive adheres to the rollers that apply the adhesive and the transport rollers in the paper path after application, and hardens. The uniform smooth surface was damaged, which hindered the adhesive application work and the transportation work, and often required complicated maintenance inspection.

Moreover, in order to evenly apply the adhesive to the back surface of the paper, a special roller or the like for leveling the applied liquid adhesive layer is provided, and the maintenance and inspection of this roller causes a lot of loss. there were.

Further, in the latter method and apparatus for producing a postcard using a double-sided adhesive tape, it is necessary to peel off the release liner (release sheet) covering both surfaces of the adhesive tape, and moreover, the adhesive is easy to stick after peeling. There are many problems such as the release of the release liner, which leads to environmental pollution, as well as the exposed surface of the agent makes it difficult to handle.

Further, the device requires a device for peeling off the double-sided adhesive tape, and the adhesive tape until the postcard is adhered after the peeling sticks to the conveying path, and this reaches the paper conveying path, so that the smooth conveying is possible. It was a troublesome thing that required maintenance and inspection because the supply and transportation were hindered.

Therefore, in each of these conventional methods and apparatuses for sticking postcards to paper in the postcard making method, the sticking efficiency is poor and the postcard making cost is high.

The present invention is intended to solve the problems in the pasting method and apparatus in the conventional postcard making, and as another object, the sticking efficiency in the postcard making means using the heat-sensitive adhesive. It is to solve various problems such as the constitution of the heat-sensitive adhesive, the method of thermocompression bonding, and the means for further improving the above.

[0009]

The present invention proposes the following means in order to achieve the above object in the method and apparatus for making a post card.

First, in a method of forming a postcard by sticking a postcard on the back surface of a paper on which an image is formed using an adhesive, heat of a constant temperature is applied between the paper on which the image is formed and the postcard. The method is characterized in that an adhesive that melts and exerts an adhesive force, that is, a heat-sensitive adhesive is laid on top of each other, and this is heated and pressed with heat of a constant temperature to integrally bond the paper and the postcard. .

By using a heat-sensitive adhesive, since the adhesive before heating does not exert an adhesive force at room temperature, the adhesive can be easily interposed between the paper and the postcard without sticking the adhesive to the paper. The adhesive becomes easy to handle in sticking, and the sticking work becomes easy because the adhesive is melted and adhered by pressure only after heating.

As one of the heat-sensitive adhesives in the method, a heat-sensitive adhesive is applied on both sides of a thin sheet to form an integrally processed adhesive sheet, so that the paper and the postcard are evenly and properly interposed and heated. It becomes easy to crimp.

As another heat-sensitive adhesive, a heat-sensitive adhesive is directly coated on the back surface of the paper to integrally form the heat-sensitive adhesive, so that the postcard is directly laminated on the paper and the adhesive is interposed. Since the adhesive layer can be omitted, an adhesive layer that is even over the entire surface can be easily obtained, and the adhesive strength is increased.

Next, as an image forming device, in a device for forming a postcard by sticking a postcard with an adhesive on the back surface of a paper on which an image is formed, a paper from an image forming paper supply device is used. A device that supplies an adhesive sheet that is integrally processed and formed by applying a heat-sensitive adhesive that melts and exerts adhesive force by applying heat at a constant temperature to both sides of a thin sheet in the transport path, and a device that supplies a postcard And a thermocompression bonding device on the lower side of these devices.

Further, as another producing device, a postcard is provided in a paper feeding path from a paper supply device in which a heat-sensitive adhesive is coated on the back side of a paper on which an image is formed to integrally form the heat-sensitive adhesive. An apparatus comprising a supply device and a thermocompression bonding device provided on the lower side of the device.

In these preparation devices, since the adhesive strength of the adhesive sheet before heating or the adhesive on the back surface of the paper does not work at room temperature, the adhesive is adhered to the feeding path of the paper and the adhesive sheet and is smoothly conveyed without being contaminated. It is possible to press paper and postcards with an adhesive sheet or adhesive melted with a thermocompression bonding device.

In the device using the heat-sensitive adhesive integrally formed on the back surface of the paper, since the postcard can be directly overlaid on the paper and heat-pressed, the adhesive supply device can be omitted, and the operation and the device can be reduced. It can be simplified.
