However, if the removable signatures are saddle-stitched in advance and are inserted into a cover paper, you can combine these signatures with regular signatures that are not saddle-stitched for perfect binding. In this case, there was a drawback that the saddle stitched portion was cut off when cutting to align the back portions. In this case, the meaning of the middle spelling in advance would be completely lost.

[Problems to be solved by the invention] The present invention was made in order to solve the problems of the conventional methods. The present invention aims to provide a book structured so that it can be bound without cutting off the middle binding portion when trimming the spine.

[Means for Solving the Problems] As a means for solving these problems, the present invention uses a plurality of signatures and a signature containing a saddle-stitched booklet in a double-fold cover binding. A book that is bound together with a set of two books, the gist of which is that a hole is provided in the side surface near the back of the cover paper for the adhesive to penetrate, and a signature containing the cover paper is pasted up against the signature. It is.

[Function] With such a configuration, the present invention can prevent the saddle stitched portion from being cut off due to up-sticking when trimming the back portion during perfect binding.

[Example] This invention will be explained in more detail below with reference to the illustrated example.

After that, before the cover pasting process, the spine of the signature A is cut along the cutting line C or roughened to increase the binding strength and to improve the adhesion of the adhesive 5. Since it is pasted upward as described above, it is not cut or roughened, and the saddle stitch 2 is left as it is. Then, adhesive is applied to the trimmed back portion and the cover 6 is attached. In addition, the cover paper may be a folded in half 8-page, 16-page, or 32-page signature in addition to the illustrated 4-page signature, and even if one side is short on the edge side. good.
