BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for adhering paper powder media of different sizes to an adhesive application part at the time of temporary bookbinding using an adhesive such as hot melt, glue, bond, etc. It is about.

[0002]

2. Description of the Related Art In order to bind a book such as a book or a magazine, there is a temporary bookbinding step of binding a large number of printed sheets, and a bookbinding step that follows this temporary bookbinding step. In order to prevent the signatures from moving during the process, wire binding, thread binding, ajiro binding, wireless binding, and the like have been used. For the wire binding, the fold part of the signature that has been collated is bound with a staple like a staple, and the cover and the contents are collated at one time and folded once, and the staple line is like a staple. Although there is a saddle stitch that is stapled, such a wire stitch is advantageous when there are few signatures, and is not suitable because it is difficult for the needle to penetrate when binding a thick book or the like. In the next thread binding, a plurality of signatures are bent with a thread, and these are further bonded by using an adhesive. However, bookbinding using this thread binding has a problem of high cost. At the time of folding a paper sheet, the ajiro stitch makes a hole in the finger part of the paper sheet,
In this way, adhesive is inserted into the holes of the signatures with holes to bond the signatures together, but generally, for signatures printed by rotary printing, the It could only be used in some books because it couldn't contain. Wireless binding mechanically cuts sawtooth-shaped irregularities on the back of each signature, and after finishing the gathering, apply adhesive to the cuts to join the backs and cut into each signature After arranging a notch type that allows the unevenness to be adhered to each other and a folded signature that has already been gathered, cut the back part for about 3 mm, and then separate this into the state of each sheet , Scratch each cut surface to make it rough, apply an adhesive to this rough surface, and further attach a medium such as paper or cloth to this adhesive application part and bond each paper sheet integrally is there. In the case of temporary binding by either the cutting type or the cutting type, each page can be sufficiently opened to the throat of the binding. Therefore, the printing plate of the book can be made large, and the printing area of each page can be widened, which is widely adopted.

However, in this wireless binding, a hot-drying (synthetic resin-based adhesive) having a quick-drying property must be used as the adhesive applied to the cut surface of each sheet. When hot melt is used, the vinyl-based bond or glue such as glue used in the subsequent process does not adhere to the hot melt coated surface, so attach paper or cloth (brown gauze) etc. on the hot melt coated surface. Adhesive media such as tape-shaped paper and cloth are used to improve the adhesiveness of the adhesive used in the process.

[0004]

When a tape-shaped (wide) adhesive medium is stuck in a wireless binding, it is difficult to give the roundness or the squareness peculiar to bookbinding,
Moreover, because of the strong restoring effect, it is difficult to bind a clean book. Also, by putting an adhesive medium such as paper or cloth on the spine, there is a risk that the book will not open well and the spine will crack or the text will fall off when trying to open it forcibly.
