Widely used.

In these collating machines, bookbinding devices, etc., a predetermined number of signature feeders are installed in one collating machine or bookbinding surface.

[Problem that the invention seeks to solve]

However, the number of signatures that make up the book that should be manufactured.

It varies depending on the true number of books, the number of pages of signatures, etc. Therefore, when binding is performed using the bookbinding apparatus, the number of required signatures and the number of signature feeders may not match.

If the number of signatures is greater than the installed signature feeder, the predetermined number of signatures are collated and temporarily bound, and the collection of signatures is conveyed to the signature feeder of the bookbinding device again.

It requires a time-consuming and complicated process of setting and completing bookbinding, and is prone to quality defects such as misalignment. To avoid this, it is sufficient to provide a large number of signature feeders in advance, but when a large number of signature feeders are provided, the number of signatures is often smaller than the signature feeders.

In that case, the problem arises that the expensive signature feeder becomes idle.

The present invention has been made in view of such conventional problems.
Effectively use multiple collating machines or bookbinding devices.

It is an object of the present invention to provide a saddle stitch binding method that enables binding of a small number of folds or a large number of folds.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is provided with a signature conveying means consisting of a thin endless strip, and an Xti signature conveying means, which is provided along the Xti signature conveying means, and which opens the signature and transfers the signature to the strip of the signature conveying means.
