Abstract

A device for shaping a folding region of a lying outstretched book cover includes first and second shaping tools for book blocks having straight and round spines, respectively. A countertool has two counter shaping rails. In a working position, one of the shaping tools is 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 to form a spine strip. A single actuator for the shaping tools is in each case arranged in the working position. A tool beam is in each case arranged in the working position and configured to be coupled to the single actuator. Each shaping tool has two shaping rails which are spaced apart, laterally adjustable and are designed so as to be adjustable collectively to change a distance therebetween.

First claim

What is claimed is:

1. A device for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of a spine region, or for shaping the spine region and the folding region, corresponding to 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 first shaping tool for a first book cover associated with a first book block having a straight spine;
at least one second shaping tool configured to generate a rounding of the spine region of the book cover for a second book cover associated with a second book block having a round spine;
a working position for one of the shaping tools and a resting position for the other shaping tools;
a countertool which is aligned with an outer face of the spine region of the book cover and has two counter shaping rails which are spaced apart from one another and are adjustable laterally according to a width of the spine region of the book cover, wherein, in a working position, a respective one of the shaping tools 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 so as to form a spine strip of the book cover;
one tool beam which is non-positively or positively connected to each of the shaping tools;
a receiving element for the tool beam arranged in the working position; and
a single actuator for the shaping tools in each case arranged in the working position, the tool beam in each case being arranged in the working position being configured to be coupled to the single actuator,
wherein each of the shaping tools has two shaping rails which are spaced apart from one another, are laterally adjustable and are each designed so as to be adjustable collectively to change a distance therebetween.

2. The device according to claim 1 , wherein the actuator is arranged to a side of an imaginary vertical plane through a longitudinal central axis of the tool beam located in the working position.

3. The device according to either claim 1 , wherein at least one preheating station arranged for the at least one shaping tool located in the resting position.

4. The device according to claim 3 , wherein the at least one preheating station is arranged in or on the device or in a vicinity of the device.

5. The device according to claim 4 , wherein a separate preheating station is arranged for each one of the shaping tools.

6. The device according to claim 1 , wherein at least one sensor is arranged for identifying the shaping tools.

7. The device according to claim 6 , wherein the at least one sensor is arranged in at least one preheating station.

8. The device according to claim 6 , wherein the at least one sensor is arranged on the receiving element for the tool beam.

9. The device according to claim 1 , wherein the at least one first shaping tool has two shaping rails which are spaced apart from one another and are arranged so as to be laterally adjustable according to the width of the spine region of the book cover.

10. The device according to claim 1 , wherein the at least one second shaping tool has a fixed central shaping strip, which is rounded towards the countertool, and two outer shaping rails, which are arranged to the sides of the central shaping strip and are laterally adjustable according to a rounding and the width of the spine region of the book cover, the shaping rails being rounded towards the countertool.

11. The device according to claim 10 , wherein the central shaping strip is symmetrical and has a recess on either side of a region facing the tool beam configured to receive the outer shaping rails, at least in part.

12. The device according to claim 11 , wherein the outer shaping rails are adjustable symmetrically to a longitudinal central axis of the central shaping strip.

13. The device according to claim 1 , further comprising at least two first shaping tools, each suitable for different thickness categories of different spine regions of the book covers to be shaped, and at least two second shaping tools, each suitable for different thickness categories of different spine regions of the book covers to be shaped.

14. The device according to claim 1 , wherein the receiving element is designed as a heating element.
