Abstract

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.

First claim

What is claimed is:

1. A device for applying portions of a backlining material to backs of book blocks, the device comprising:
a conveying apparatus configured to transport the book blocks through a book production line in a conveying direction;
a single pasting apparatus configured to apply an adhesive over an entire back length of the backs of the book blocks;
at least one backlining station comprising at least one supply apparatus configured to supply the backlining material and at least one cutting apparatus configured to cut the portions of the backlining material to length in accordance with a thickness of the back of a respective one of the book blocks to be supplied with the backlining material;
a first conveying device disposed after the single pasting apparatus in the conveying direction and configured to apply at least a first portion of the backlining material; and
at least one second conveying device disposed after the first conveying device in the conveying direction and configured to apply at least a second portion to the backs of the book blocks such that, in each case, at least one of the portions overlaps another one of the portions,
wherein the single pasting apparatus is the only pasting apparatus of the device.

2. The device according to claim 1 , wherein the conveying devices each comprise a suction element having a first segment and at least one second segment, each of the suction elements being configured to receive, temporarily hold and release a respective one of the portions of the backlining material.

3. The device according to claim 2 , wherein each of the first segments comprise a first face configured to contact the backs of the book blocks and each of the at least one second segments comprises a second face configured to contact the backs of the book blocks, each of the at least one second segments being formed so as to be offsettable with respect to a respective one of the first segments in such a way that the contact face of the first segment touches the back of the book block whilst a contact face of the at least one second segment is at a distance from the back of the book block.

4. The device according to claim 2 , wherein, in each case, an actuator configured to offset the at least one second segment with respect to the first segment is arranged on the suction element.

5. The device according to claim 2 , wherein each of the suction elements is arranged on a respective one of the conveying devices so as to be replaceable with another, different suction element.

6. The device according to claim 2 , wherein at least one of the first segment and the at least one second segment is arranged on relevant respective one of the suction elements so as to be replaceable with another, different segment.

7. The device according to claim 1 , wherein at least two of the supply apparatuses for the backlining material are arranged upstream from the first conveying device and/or upstream from the second conveying device and are offset from one another in the conveying direction in such a way that the backlining material for the first portion and the backlining material for at least one third portion are supplyable to the first conveying device in an overlapping manner and/or the backlining material for the second portion and the backlining material for at least one fourth portion are supplyable to the second conveying device in an overlapping manner.

8. The device according to claim 1 , wherein at least two of the backlining stations are arranged in succession in the conveying direction of the book blocks through the book production line so as to form a joint tandem backlining station comprising at least one of the supply apparatuses in each case configured to provide the portions of the backlining material.

9. The device according to claim 1 , wherein each of the conveying devices is assigned a first supply apparatus and a second supply apparatus for the backlining material, the second supply apparatus in each case being switchable by a machine control system in accordance with a respective size of a respective one of the book blocks to be provided with the portions of the backlining material.

10. A book production line comprising a device according to claim 1 .

11. A device for applying portions of a backlining material to backs of book blocks, the device comprising:
a conveying apparatus configured to transport the book blocks through a book production line in a conveying direction;
a single pasting apparatus configured to apply an adhesive over an entire back length of the backs of the book blocks;
at least one backlining station comprising at least one supply apparatus configured to supply the backlining material and at least one cutting apparatus configured to cut the portions of the backlining material to length in accordance with a thickness of the back of a respective one of the book blocks to be supplied with the backlining material;
a first conveying device disposed after the single pasting apparatus in the conveying direction and configured to apply at least a first portion of the backlining material; and
at least one second conveying device disposed after the first conveying device in the conveying direction and configured to apply at least a second portion to the backs of the book blocks such that, in each case, at least one of the portions overlaps another one of the portions,
wherein the conveying devices each comprise a suction element having a first segment and at least one second segment, each of the suction elements being configured to receive, temporarily hold and release a respective one of the portions of the backlining material, and
wherein each of the first segments comprise a first face configured to contact the backs of the book blocks and each of the at least one second segments comprises a second face configured to contact the backs of the book blocks, each of the at least one second segments being formed so as to be offsettable with respect to a respective one of the first segments in such a way that the contact face of the first segment touches the back of the book block whilst a contact face of the at least one second segment is at a distance from the back of the book block.

12. A device for applying portions of a backlining material to backs of book blocks, the device comprising:
a conveying apparatus configured to transport the book blocks through a book production line in a conveying direction;
a single pasting apparatus configured to apply an adhesive over an entire back length of the backs of the book blocks;
at least one backlining station comprising at least one supply apparatus configured to supply the backlining material and at least one cutting apparatus configured to cut the portions of the backlining material to length in accordance with a thickness of the back of a respective one of the book blocks to be supplied with the backlining material;
a first conveying device disposed after the single pasting apparatus in the conveying direction and configured to apply at least a first portion of the backlining material; and
at least one second conveying device disposed after the first conveying device in the conveying direction and configured to apply at least a second portion to the backs of the book blocks such that, in each case, at least one of the portions overlaps another one of the portions,
wherein the conveying devices each comprise a suction element having a first segment and at least one second segment, each of the suction elements being configured to receive, temporarily hold and release a respective one of the portions of the backlining material, and
wherein, in each case, an actuator configured to of
