Abstract

The magazine for embossing rollers includes a plurality of support seats for embossing rollers, adjacent to one another according to an alignment direction. The magazine further includes a guide system for guiding the seats in a handling direction. The seats are provided with mutual connecting members so as to be connected to, and released from, one another.

First claim

The invention claimed is:

1. A magazine for embossing rollers comprising:
a plurality of support seats for embossing rollers, adjacent to one another according to an alignment direction;
a guide system for guiding the seats in a handling direction;
wherein the seats are provided with mutual connecting members so as to be connected to, and released from, one another, in order to extract each of the seats from the magazine independently of another one of the seats.

2. The magazine according to claim 1 , wherein said seats are extracted from, and inserted into, the magazine by means of a movement according to an insertion and extraction direction not parallel to the handling direction.

3. The magazine according to claim 2 , wherein the mutual connecting members are configured to allow mutual connection and release of the seats by means of a connecting and releasing movement according to the insertion and extraction direction.

4. The magazine for embossing rollers according to claim 3 , wherein the insertion and extraction direction is substantially orthogonal to the handling direction.

5. The magazine for embossing rollers according to claim 2 , wherein the insertion and extraction direction is substantially orthogonal to the handling direction.

6. The magazine for embossing rollers according to claim 1 , wherein the seats are provided in sections of a carriage that is movable in the magazine according to the alignment direction.

7. The magazine for embossing rollers according to claim 6 , wherein the guide system comprises two longitudinal parallel guides defining therebetween a translation space for the carriage, and wherein each of the seats of the carriage is provided with engagement elements for engaging with the longitudinal guides.

8. The magazine for embossing rollers according to claim 7 , wherein each of said two longitudinal parallel guides has a gap in an intermediate position along a longitudinal extension thereof; each said gap of the two longitudinal parallel guides being aligned in the insertion and extraction direction and defining an extraction and insertion station for extraction of the seats from, and insertion of the seats into, the translation space.

9. The magazine for embossing rollers according to claim 8 , further comprising two longitudinal guide portions, which can be separated from the two longitudinal parallel guides and are configured so as to be inserted in the gaps of the longitudinal parallel guides and aligned therewith, so as to form continuous longitudinal guides.

10. The magazine for embossing rollers according to claim 9 , wherein the two longitudinal guide portions are connected to one another by connection bars.

11. The magazine for embossing rollers according to claim 9 , wherein the two longitudinal guide portions are selectively coupled to one of the seats which is positioned in the extraction and insertion station.

12. The magazine for embossing rollers according to claim 11 , wherein at least one of said longitudinal guide portions is connected to a first motor, configured and arranged to move the longitudinal guide portions, and a seat connected thereto, in the insertion and extraction direction.

13. The magazine for embossing rollers according to claim 8 , further comprising a transverse guide system to move the seats in the insertion and extraction direction, the transverse guide system extending in the extraction and insertion station.

14. The magazine for embossing rollers according to claim 13 , wherein each of the longitudinal guide portions is provided with engaging members for engaging with the transverse guide system.

15. The magazine for embossing rollers according to claim 1 , wherein the seats are fastened to a motorized auxiliary section, provided with a second motor to move the seats in the handling direction.

16. An embossing device comprising:
a bearing structure;
at least one embossing roller provided with embossing protuberances;
at least one pressure roller defining, with the embossing roller, an embossing nip;
a magazine for embossing rollers according to claim 1 , integrated in the bearing structure.

17. The embossing device according to claim 16 , further comprising a handling member to transfer embossing rollers from and towards said magazine for embossing rollers.
