Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a corded selvage paper to an electrical recording mimeograph paper.

Generally, electrical recording mimeograph paper is made by uniformly kneading conductive inorganic fine powder (e.g. carbon powder, etc.) into film-molding resin such as synthetic resin to form a thin film, and then stacking this film on a backing paper provided with a conductive layer. This is a mimeograph original plate that is electrically recorded and made.

By the way, I will explain how to use electronic recording mimeograph paper.

First, in order to make a plate using electrical recording mimeograph paper (obtain a perforated image), a discharge recording device equipped with a scanning cylinder and a discharge needle is used to optically scan the original image line and adjust the image to correspond to the original image line. The perforation image is obtained by destroying the film in the area to be damaged by electrical discharge.

Next, only the mount part of the base paper is removed (perforations etc. are provided in the necessary parts of the mount paper to facilitate removal), and only the film with the perforated image is loaded into a mimeograph machine, and then It is a mimeographed method.

In other words, electrical recording mimeograph paper is attached to an electric discharge recording device and a rotary mimeograph press to serve as a mimeograph printing plate, but as mentioned above, the base paper is made of a thin synthetic resin film and a mount. Because of this, a piece of paper is generally attached to the end for attachment to the above-mentioned equipment.

By the way, there are usually two methods for loading the base paper into the rotary press of a mimeographing machine.

In the first method, a hook 2 as shown in FIG. 1 is provided on a mounting mechanism (hereinafter simply referred to as a head) for attaching the base paper to a rotary press, and a mounting hole 3 formed in the edge paper is provided. Most of the mimeograph machines in general use today are based on this method. The second method is
As shown in the figure, this is a method in which a presser metal fitting 4 that slides from side to side is provided on the head in place of the above-mentioned hook, and the selvage paper 1 is thereby held. This method is used in West German Geher and Roto mimeograph machines, but it is not suitable for the paper used in this method to have only the mounting holes of the first method. Insert a string into the edge of the selvage paper to make this part thicker, and then the selvage paper will fit into the presser metal fitting 4.
It is necessary to devise ways to prevent this from happening.

By the way, most of the mimeograph machines currently in general use in Japan have heads made by the first mounting method described above, so the electrical recording mimeograph paper distributed here has mounting holes. Those with selvage paper are the mainstream. Therefore, if you want to import and use mimeograph machines manufactured by the two West German companies mentioned above, you will have to first modify the head structure to a hook type, and conversely, you will have to import mimeograph machines made by the two West German companies. Currently, when exporting to a country that uses the mimeograph machines manufactured by the two companies mentioned above, special stringed paper is pasted by hand. Furthermore, since this is done by hand, productivity is extremely low, and defective products are likely to occur due to dimensions and other issues.

The present invention was made in view of the above circumstances, and
The purpose is to provide a method for attaching stringed selvedge paper extremely efficiently and accurately, thereby increasing the productivity of the base paper and reducing the number of defective products.

That is, the present invention involves the step of making a linear perforation in the vicinity of the center of the original fabric of selvage paper, which has been coated with a solvent-based adhesive and dried, and continuously attaching a string to the perforation. , a step of re-wetting the selvage paper material and string together with a solvent while stacking them together, a step of folding the selvage paper material in half along the perforations, and a process that parallels this process. The present invention is characterized by the steps of continuously supplying the electrical recording mimeograph material and sandwiching it between the two-folded paper sheet, crimping it, and cutting it into predetermined dimensions. This is a method in which a piece of paper with a string is attached to the mimeograph paper for electrical records.

Hereinafter, the present invention will be explained in detail with reference to FIGS. 3 and 4.

In FIG. 3, a selvage paper material 20 of a predetermined width, which has been coated with a solvent-based adhesive that can be rewetted with a solvent on one side and dried, is wound into a roll and pooled on a stand 6 in FIG. The reason for using solvent-based adhesives is
If a drying process is performed after pasting the paper, there is a risk of harmful heat shrinkage wrinkles occurring on the film surface of the electrical recording paper. This is because an adhesive, that is, a solvent-based adhesive is required.

By the way, in the present invention, the above-mentioned selvage paper material is continuously fed to the pasting mechanism. First, the selvage paper material material 20 is first placed at a predetermined position near the center of the selvage paper material material 20 using the sewing machine blade 7. Add a perforation to serve as the crease when folding in half.

In addition, the string 5' pooled on another stand is continuously fed by a guide roller 8 so as to be accurately aligned with the creases (perforations) of the above-mentioned selvage paper material, and then the solvent coating roll 9 is applied. The solvent-based adhesive applied to the selvage paper material on the roll 10 is rewetted using the adhesive. The roll surface of the solvent application roll 9 is made of a sponge-like porous material, and one end thereof is in contact with the solvent in the solvent vat 11, so that the roll surface is always kept moist with the solvent.

Next, the original sheet paper is folded in half along the crease (perforation) by the guide plate 12 with the adhesive coated surface facing inside. At this time, a separately fed electric recording mimeograph original paper 18 is sandwiched between the folded edge paper originals.

As mentioned above, the original electrical recording mimeograph paper is constructed by overlapping the synthetic resin film 18'' and the mount 18', but since the mount is removed after platemaking, the necessary parts of the mount (the fourth (shown in the figure) is provided with a perforation 13 to facilitate removal.The selvage paper must be attached so that it is located at the end of this perforation 13, but this positioning is done by sliding it left and right. This is done by manipulating a guide roll 14 that can be moved. Therefore, a sufficient distance is maintained between the guide roll 14 and the rolls 15 and 16 to facilitate the above-mentioned sliding. It is something.

Note that the string must be securely inserted into the edge of the selvage paper, that is, in the fold created by the perforation, but
As shown in the figure, the string is fed along the perforation and is stretched between the nip roll 17 and the guide roller 8, so even when the selvage paper material is folded in half by the guide plate 12. The string will not come out of the perforation, and will therefore be securely inserted into the fold or edge of the selvage paper.

Then, the next rotary cutter 19 cuts the electrical recording mimeograph paper into a specified size.

The electrical record copying paper cut into specified dimensions as described above can be cut into a desired shape by using a punching machine provided separately from the present invention, or by punching mounting holes using a general method. Even if I do, I can't really blame you. Rather, in this way it is also possible to obtain a selvage paper that is compatible with both of the mounting methods described above (attachment of the electrical recording paper to the rotary press head).

According to the processing method of the present invention, it is possible to attach the stringed selvage very easily, and it is also possible to obtain a product with high dimensional accuracy.
