Abstract

A shaping tool for a device for rounding a spine region and for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of the spine region, in accordance with a shape of a spine of a book block, which subsequently forms a book together with the book cover, includes a fixed, convex central shaping strip. Two convex outer shaping rails laterally adjoin the central shaping strip and are laterally adjustable according to a required rounding and width of the spine region of the book cover.

First claim

What is claimed is:

1. A shaping tool for a device for rounding a spine region and for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of the spine region, in accordance with a shape of a spine of a book block which subsequently forms a book together with the book cover, the shaping tool comprising:
a fixed, convex central shaping strip; and
two convex outer shaping rails, which laterally adjoin the central shaping strip and are laterally adjustable according to a required rounding and width of the spine region of the book cover.

2. The shaping tool according to claim 1 , wherein the shaping tool has a tool beam which is non-positively or positively connected to the central shaping strip and the outer shaping rails.

3. The shaping tool according to claim 2 , wherein the central shaping strip is symmetrical and has a recess on either side in a region facing the tool beam configured to receive the outer shaping rails at least in part.

4. The shaping tool according to claim 1 , wherein the outer shaping rails are designed so as to be adjustable symmetrically to a longitudinal central axis of the central shaping strip.

5. A device for rounding a spine region and for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of the spine region, in accordance with a shape of a spine of a book block which subsequently forms a book together with the book cover, the device comprising:
at least one shaping tool comprising:
a fixed, convex central shaping strip and
two convex outer shaping rails, which laterally adjoin the central shaping strip and are laterally adjustable according to a required rounding and width of the spine region of the book cover.

6. The device according to claim 5 , wherein the at least one shaping tool is arranged so as to interact with a countertool which is aligned with an outer face of the spine region of the book cover.

7. The device according to claim 6 , wherein the countertool has two counter shaping rails which are spaced apart from one another and are adjustable laterally according to the width of the spine region of the book cover.

8. The device according to claim 5 , wherein the device includes at least two different shaping tools, which are configured for different thickness categories of spine regions of book covers to be shaped.

9. The device according to claim 8 , wherein the device has a working position for a first shaping tool and one resting position each for at least one second shaping tool.

10. The device according to claim 9 , wherein the first shaping tool which is located in the working position is arranged so as to be aligned with an inner face of the spine region of the book cover and is configured to raise the spine region of the book cover between the two counter shaping rails and so as to form a spine strip of the book cover.

11. The device according to claim 9 , further comprising at least one preheating station arranged for the at least one second shaping tool which is located in the resting position.

12. The device according to claim 11 , wherein a separate preheating station is arranged for each shaping tool.

13. The device according to claim 5 , further comprising at least one sensor configured to identify the shaping tools.

14. The device according to claim 13 , wherein the at least one sensor is arranged in at least one preheating station and is aligned with a second shaping tool located in a resting position, or is arranged on a receiving element for a tool beam and is aligned with the at least one shaping tool located in a working position.

15. The device according to claim 5 , wherein a tool beam of a respective shaping tool arranged in a working position is designed such that the tool beam is coupleable to an actuator, which is arranged to a side of an imaginary, vertical plane through a longitudinal central axis of the tool beam arranged in the working position.
