Description

The present invention relates to a saddle stitch bookbinding method.

[Conventional technology]

The signature conveying means is composed of a thin endless belt like an endless roller chain, and many signature feeders are provided along the signature conveying means, and the signatures are opened one after another on the running endless belt. Collating machines that collate by putting them on are widely used. In addition, a saddle stitching device in which a spine binding machine (hereinafter referred to as a stitcher) is provided at the downstream end of the signature conveying means of this collator to perform saddle stitching and then trimming is performed by a trimming machine is also widely used. It is used. In these collator, bookbinding device, etc., one collator or bookbinding device is equipped with a predetermined number of signature feeders.

[Problems to be solved by the invention]

Therefore, when bookbinding is performed in a certain bookbinding apparatus, the number of signatures naturally required may not match the number of signature feeders. If the number of signatures is greater than the number of installed signature feeders, a certain number of signatures will be collated in advance and temporary binding will be performed, and the stack of signatures will be conveyed again to the signature feeder of the bookbinding device and set for bookbinding. Requires a complicated and complicated process to complete
Quality defects such as incorrect collation are likely to occur. To avoid this,
It is sufficient to install a large number of signature feeders in advance, but if a large number of signature feeders are provided, the number of signatures will often be smaller than that of a signature feeder, in which case the expensive signature feeder becomes idle. That is the problem.

The present invention has been made in view of the above conventional problems,
An object of the present invention is to provide a saddle stitch bookbinding method that enables bookbinding with a small number of signatures and a large number of signatures by effectively using a plurality of collating machines or bookbinding devices.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a signature conveying means composed of a thin endless belt and a signature conveying means provided along the signature conveying means and opening the signature to form a belt-like body of the signature conveying means. At least two collating machines each having a plurality of signature feeders to be placed are provided so that each signature conveying means is in series, and one signature conveying means rear part and another signature conveying means front part are provided. The signatures are connected by the signature transfer means, and the signatures that are aligned by one signature transfer means are transferred to the front part of the other signature transfer means.

[Action]

As described above, the present invention supplies a signature from one collator to the other collator, so that the number of signature feeders provided in one collator is increased without increasing the number of signature feeders. Enables bookbinding with a large number of pages. Further, in the case of binding with a small number of signatures, by using each collating machine for different binding, the signature feeder is always used effectively without being idle.
