However, such a conventional thick letter and thin paper interleaving method has a problem that it is not possible to satisfy both the required productivity and mass productivity.

For example, a long paper 2 unwound from a first roll 1 and a long thin paper 7 unwound from a second roll 2 shown in FIG. In this case, since both the thick letter 2 and the thin paper 7 are in the form of a long roll, the production lot of the produced slip sheet becomes large, and there is a problem that it is not possible to cope with the production of a small lot of slip sheet.

Further, as shown in FIG. 4, a method of gluing one side of a thick letter 13 in the form of a plain paper, and then superimposing the thin papers 7 by hand and bonding them together by pressing, involves a main step of laminating the thin papers 7. Due to the reliance on human labor, there is a disadvantage in that the work efficiency is limited and mass productivity is poor, resulting in an increase in product cost.

Therefore, the present invention has solved the problems of the conventional thick letter and thin paper interleaving method, and has made it possible to cope with the production of small lot interleaf paper and to improve the mass productivity. It is an object to obtain a bonding method and a device therefor.
