Abstract
A method for processing a sheet for bookbinding includes operations. A cut is formed that divides a thickness of the sheet in a binding-side side surface of the sheet. A portion of a connection piece that is attached to the sheet is inserted into the cut as an inserted portion, and functions as a hinge in a book-bound state. The portion of the connection piece inserted into the cut is joined to the sheet.
Claims18
A method for processing a sheet for bookbinding, the method comprising:
- forming a cut that divides a thickness of the sheet in a binding-side side surface of the sheet;
- inserting, into the cut, a portion of a connection piece that is attached to the sheet and functions as a hinge in a book-bound state;
- and
- joining, to the sheet, the portion of the connection piece inserted into the cut,
- wherein the cut is formed by a cutter as a slit-shaped cut along the binding-side side surface with a predetermined depth, and
- wherein the slit-shaped cut divides the thickness of the sheet into two in the binding-side side surface of the sheet, where the sheet is retained on a retaining stand.

- and
- a connection piece having a non-insertion part that includes surfaces,
- wherein a portion of the connection piece is inserted into the cut of each sheet and joined to each sheet, and
- wherein the plurality of sheets are bound to each other via the connection piece,
- wherein one spacer of a pair of spacers is provided on each surface of the non-insertion part of the connection piece,
- wherein the non-insertion part is not inserted into a sheet,
- wherein the pair of spacers is provided at a predetermined distance from an insertion part of the connection piece inserted into the sheet, and
- wherein a plurality of connection pieces and a plurality of pairs of spacers are bound so that they are book-bound and a gap area between the insertion part of the connection piece and the plurality of pairs of spacers form a hinge.
