Description

[Detailed explanation of the invention] This invention is a continuous or single sheet with various information printed in advance, including variable information, cut or folded using a printing device such as a computer. Pressure, heat, or A place where sealed letters, booklets, postcards, cards, forms, etc. are created by applying water or applying adhesive to the desired areas of the overlapping surfaces of the sheets after printing to adhere the overlapping surfaces of the sheets at the desired locations. This invention relates to an adhesive device.

Conventionally, sealed letters are made by gluing the overlapping surfaces of unit sheets, which are made by stacking two or more sheets that are cut and stacked or folded or two or more folded sheets, at a desired location.
In an adhesive device for creating booklets, postcards, etc., sheets are printed and superimposed using a printing device such as an electronic computer, especially a printing device such as a xerography method that forms images including characters, symbols, codes, etc. using toner. When processing a sheet with a printed image exposed on the surface of the sheet, the toner on the sheet surface will adhere to the pressure roller of the adhesion device, and if processing continues for a long time, more toner will adhere and the toner will be damaged. In some cases, a lump of particles was formed on the surface of the pressure roller. This clump of adhered toner stains the adhesive sheet and sometimes causes damage to the sheet.

Additionally, when toner or other dirt adheres to the pressure roller, the cover of the pressure roller is usually removed and a solvent is used to wipe off the dirt on the surface of the pressure roller. If processing continues for a long time with a large amount of toner adhered to the machine, the toner will become stuck and difficult to wipe off, which will take time and be very inconvenient in terms of work efficiency. Ta.

In view of these points, this invention was developed in such a way that even if images containing characters, symbols, codes, etc. are printed using a toner-based printing device such as the xerography method, and the overlapping sheets with the printed surfaces exposed are bonded, the toner will not be used. It is an object of the present invention to provide a bonding device that does not stain or damage the sheet and has a simple structure and is easy to adjust and operate.

Next, this invention will be explained based on drawings showing one embodiment of this invention.
