BOOKBINDING DEVICE AND BOOKBINDING SYSTEM
Document Type and Number:
Japanese Patent JP2015003436
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve high-quality case binding even when coating thickness of glue changes under various conditions in a case binding process.SOLUTION: A bookbinding device has a binding function which accumulates sheets of a main-sheet part as a paper bundle and covers the paper bundle with a cover sheet. The bookbinding device includes: a crease forming part for forming a first crease and a second crease at a tip part of an area where the paper bundle is glued to the cover sheet; a bookbinding part for gluing the cover sheet by coating a back part of the cover sheet with glue, folding the cover sheet along the crease, and binding the paper bundle while covering it with the cover sheet; and a control part for controlling the crease forming part and the bookbinding part. The control part controls a distance between the edge and the crease of the cover sheet so as to be longer than a distance between the edge and the back of the sheet depending on an adhesive condition of the paper bundle and the cover sheet.
