  • Patent number: 9061538
    Abstract: Bookbinding unit enabling, in encasing inner-leaf sheets in coversheets to form booklets, secure book-forming binding regardless of whether the inner-leaf sheets constitute a simple-sheet bundle or are made up of a plurality of folded-over signature sheets. Constituent components are: inner-leaf sheet tray; coversheet tray; bookbinding process path for guiding sheets from the inner-leaf sheet tray to successive adhesive-application and cover-binding locations; inner-leaf conveyor; coversheet conveyor for conveying coversheets to the cover-binding location; bundle-spine adhesive applicator in the adhesive-application location; and cover binder in the cover-binding location. Components' controller is configured to receive input as to whether inner-sheet-bundle makeup includes saddle-stitch sheets or is of simple sheets only, and, based on the bundle makeup information, varies its control of at least one of the coversheet conveyor, adhesive applicator, and cover binder.
