Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle stitching method and apparatus for binding a catalog or the like.

[0002]

Conventionally, printed materials such as catalogs have been produced in large quantities with the same contents. However, with the recent diversification of needs, personalized printed materials have been developed, Along with the practical use of printing, printed materials in which pages with different contents are inserted for each individual have come to be required.

In the case of producing personal prints, it is conceivable to combine outputs from a plurality of types of printing presses in view of cost and the like. It is difficult to bind this with a conventional automatic collating machine or automatic bookbinding machine.
The reason is as follows.

[0004] When collating sheet-fed papers, each sheet is discharged and stacked so that one corner thereof is aligned with a corner of a jogger or the like in a collating machine. When such collating is performed on the printing paper, the center is shifted between the sheet-fed printing papers, so that the wire binding becomes difficult. If you want to collate sheets of different sizes, you need to cut the other sheets to match the size of the smallest sheet and then put it on a collating machine. . However, such cutting is not preferable in terms of productivity.

[0005] As means for solving such problems,
Japanese Patent Application No. 9-905 proposes the following sheet-fed saddle stitching apparatus. That is, the apparatus includes a paper feeding unit that feeds a required number of sheet printing papers from each pile of necessary sheet printing papers, and receives the sheet printing paper sent from the paper feeding unit one by one in a tray.

According to this apparatus, even when using sheet printing papers of different sizes, or using sheet printing paper in which a picture is not printed at the center of the paper, proper printing between sheet printing papers is possible. The printed sheet can be printed by inserting a sheet of paper output by a printing machine capable of printing personalized information as appropriate.

However, the above-described sheet-fed saddle stitching apparatus temporarily fixes the sheet-fed printing paper using the temporary stapling needle, and finally pulls out the saddle-stitching needle from the sheet-fed printing paper and pierces a new binding needle. There is a problem that the binding speed cannot be increased, and there is a problem that a mechanism for replacing the temporary fixing needle and the saddle stitching needle is required and the device structure is complicated.
