A sheet binding device includes a sheet shifting unit, a tape cutter, and a tape attachment unit. The sheet shifting unit has a guide and is configured to stack multiple sheets on the guide with edge portions that are shifted from each other to form a sheet bundle. The tape cutter cuts tape with a target length that is varied in accordance with a thickness of the sheet bundle. The tape attachment unit is configured to attach the cut tape having the target length to an edge portion of the sheet bundle.

A method for applying portions of a backlining material to a back of a book block includes transporting the book block in a conveying direction in a book production line. The back of the book block is provided with an adhesive, wherein the book block is initially provided with the adhesive over an entire back length of the book block in a single application process. Then, the portions of the backlining material are applied in succession to the back of the book block, wherein at least a first portion of the backlining material is applied by a first conveying device and subsequently at least a second portion of the backlining material is applied by a second conveying device to the back of the book block such that at least one of the portions overlaps another one of the portions.

A sheet binding method according to an embodiment includes holding a sheet bundle in a state where multiple sheets forming the sheet bundle are shifted relative to each other at an edge portion of the sheet bundle. A pressing region of the edge portion is pressed, in a sheet bundle thickness direction, so that there is substantially no slack along the edge portion. While the sheet bundle is pressed, tape is applied to an edge portion of a sheet bundle at a tape attachment region of the edge portion different from the pressing region.

A sheet binding device according to an embodiment includes a tape attachment unit and a sheet support unit. The tape attachment unit includes a tap holding unit configured to hold tape that is to be applied to an edge portion of a sheet bundle at a tape attachment region of the edge portion. The sheet support unit holds the sheet bundle in a state where multiple sheets forming the sheet bundle are shifted relative to each other in the edge portion when the tape is applied by the tape attachment unit. The sheet support unit also presses, in a sheet bundle thickness direction, a pressing region of the edge portion different from the tape attachment region so that there is substantially no slack along the edge portion of the sheet bundle between the pressing region and the tape attachment region.

A sheet processing device includes a tape binding processing unit, a paper discharge unit, and a control unit. The tape binding processing unit performs tape binding processing on a sheet bundle. The paper discharge unit discharges the sheet bundle subjected to the tape binding processing onto a paper discharge tray. The control unit is configured to control at least one of the tape binding processing unit and the paper discharge unit, such that a first tape binding of the first bundle of sheets and a second tape binding of the second bundle of sheets are not in contact with each other when the first bundle of sheets and the second bundle of sheets are stacked on the paper discharge tray.
