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.

First claim

What is claimed is:

1. 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.

2. The method according to claim 1 , wherein inserting includes inserting the portion of the connection piece into the cut so that the connection piece portion takes up between 50% to 90% of a depth of the cut.

3. The method according to claim 1 , wherein the connection piece includes a film base material.

4. The method according to claim 1 ,
wherein a portion of a single connection piece is inserted into the cut of the sheet,
wherein the portion of the single connection piece has two surfaces, each have adhesive properties, and
wherein the portion of the single connection piece is joined to the sheet by closing the cut so as to bring the sheet and the portion of the single connection piece into contact with each other.

5. The method according to claim 1 , wherein the connection piece has surfaces and is provided with a spacer member on each surface of the connection piece at a predetermined distance, from the inserted portion of the connection piece.

6. The method according to claim 5 , wherein adhesive force of the connection piece in a zone between the inserted portion of the connection piece and the spacer members is smaller than adhesive force of another area.

7. The method according to claim 5 , wherein a thickness of a spacer member is equal to or less than half of the thickness of the sheet, and a combined thickness of the spacer members and the connection piece is substantially the same as the thickness of the sheet, in a state where one of the spacer members is attached to each surface of the connection piece.

8. The method according to claim 1 ,
wherein forming the cut includes forming a first cut in a first side surface of a first sheet and includes forming a second cut in a second side surface of a second sheet,
wherein inserting the portion of the connection piece into the cut includes inserting one portion of a first connection piece into the first cut of the first sheet, and inserting another portion of the first connection piece into the second cut of the second sheet, and
wherein joining the portion of the connection piece includes (i) joining the one portion of the first connection piece inserted into the first cut to the first sheet by closing the first cut of the first sheet, and (ii) joining the other portion of the first connection piece inserted into the second cut to the second sheet by closing the second cut of the second sheet.

9. The method according to claim 8 , wherein the first connection piece has a gap of a predetermined length between the portion of the connection piece joined to the first sheet and another portion of the connection piece joined to the second sheet, the method further comprising superposing the first sheet and the second sheet on each other by folding the first sheet and the second sheet at the gap.

10. The method according to claim 9 , further comprising:
inserting the portion of the connection piece into the cut such that one portion of a second connection piece is inserted into the second cut of the second sheet together with the other portion of the first connection piece,
wherein, in joining the portion of the connection piece to the sheet, the other portion of the first connection piece and the one portion of the second connection piece inserted into the second cut of the second sheet are joined to the second sheet; and
superposing the first sheet and the second sheet on each other after inserting the portion of the connection piece into the cut.

11. The method according to claim 10 , further comprising:
creating, by repeating the method according to claim 10 , a laminate of a plurality of sheets in which sheets of the plurality of sheets adjacent to each other are coupled with the connection piece; and
attaching a cover to the laminate of the plurality of sheets as a bookbinding article.

12. A bookbinding method comprising:
performing the method according to claim 1 ,
wherein the connection piece has surfaces and is provided with a spacer member on each surface of the connection piece at a predetermined distance from the inserted portion of the connection piece, and
wherein adhesive force of the connection piece in a zone between the inserted portion of the connection piece and the spacer members is smaller than adhesive force of another area; and
bundling and binding, with a cover, thea plurality of processed sheets at portions of the spacer members.

13. A bookbinding method comprising:
performing the method according to claim 1 ,
1 wherein the connection piece has surfaces and is provided with a spacer member on each surface of the connection piece at a predetermined distance from the inserted portion of the connection piece, and
wherein a thickness of a spacer member is equal to or less than half of the thickness of the sheet, and a combined thickness of the spacer members and the connection piece is substantially the same as the thickness of the sheet, in a state where one of the spacer members is attached to each surface of the connection piece; and
bundling and binding, with a cover, a plurality of processed sheets at portions of the spacer members.

14. A bookbinding article comprising:
a plurality of sheets, each having a cut in a side surface; 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.

15. The bookbinding article according to claim 14 , wherein the connection piece includes a flexible film base material.

16. The bookbinding article according to claim 14 , wherein the gap area is adjusted by an array pitch between the plurality of sheets, a thickness of the connection piece, and a deformation amount of the hinge, and a size of the gap area sequentially becomes longer from the gap area between sheets located on both ends of the bookbinding article toward thea sheet located in a center portion of the bookbinding article.

17. The bookbinding article according to claim 14 ,
wherein two connection pieces are inserted into the cut of a first sheet,
wherein each connection piece of the two connection pieces is inserted into cuts of separate sheets that are different from the first sheet, and
wherein a first
