Abstract

The embossing-laminating device includes load bearing structure with at least two side members, a first path, for a first ply of web material, and a second path for a second ply of web material. Along the first path, a first pressure roller and a first interchangeable embossing roller are arranged, which define therebetween a first embossing nip for the first ply of web material. Along the second path a second pressure roller and a second interchangeable embossing roller are arranged, which define a second embossing nip for the second ply of web material. The embossing-laminating device also includes a magazine including a plurality of seats for a plurality of interchangeable embossing rollers, as well as at least a first manipulator for replacing embossing rollers.

First claim

The invention claimed is:

1. An embossing-laminating device comprising:
a load bearing structure comprising at least two side members;
a first path, for a first ply of web material;
a second path, for a second ply of web material;
along the first path, a first pressure roller, co-acting with a first interchangeable embossing roller, the first interchangeable embossing roller and the first pressure roller defining a first embossing nip for the first ply of web material;
along the second path, a second pressure roller, co-acting with a second interchangeable embossing roller, the second interchangeable embossing roller and the second pressure roller defining a second embossing nip for the second ply of web material;
a magazine comprising a plurality of seats for a plurality of interchangeable embossing rollers;
at least one first manipulator for replacing interchangeable embossing rollers;
wherein the first manipulator is configured and controlled to selectively engage with an interchangeable embossing roller for moving said interchangeable embossing roller and release of the interchangeable embossing roller, and to selectively: take an interchangeable embossing roller from an operating position, transfer the interchangeable embossing roller to the magazine and release the interchangeable embossing roller in one of the plurality of seats of the magazine, take another interchangeable embossing roller from a respective one of said plurality of seats, transfer and release the interchangeable embossing roller into an operating position.

2. The embossing-laminating device according to claim 1 , further comprising a first support and rotation system for the first interchangeable embossing roller and a second support and rotation system for the second interchangeable embossing roller, and wherein said first support and rotation system and said second support and rotation system are configured to allow removal and replacement of the first interchangeable embossing roller and the second interchangeable embossing roller, separately from one another, by said at least one first manipulator.

3. The embossing-laminating device according to claim 2 , wherein the first pressure roller and the second pressure roller are each supported movably with respect to the load bearing structure, to take up an operating position, wherein a respective one of the first pressure roller and the second pressure roller is pressed against a respective interchangeable embossing roller, and an open position, wherein the respective one of the first pressure roller and the second pressure roller is spaced from the respective interchangeable embossing roller.

4. The embossing-laminating device according to claim 1 , wherein the first manipulator is arranged between the side members of the load bearing structure, between which the first pressure roller, the second pressure roller, the first interchangeable embossing roller, the second interchangeable embossing roller and the magazine are arranged.

5. The embossing-laminating device according to claim 2 , wherein the first manipulator is arranged between the side members of the load bearing structure, between which the first pressure roller, the second pressure roller, the first interchangeable embossing roller, the second interchangeable embossing roller and the magazine are arranged.

6. The embossing-laminating device according to claim 1 , wherein the first pressure roller and the second pressure roller are each supported movably with respect to the load bearing structure, to take up an operating position, wherein a respective one of the first pressure roller and the second pressure roller is pressed against a respective interchangeable embossing roller, and an open position, wherein the respective one of the first pressure roller and the second pressure roller is spaced from the respective interchangeable embossing roller.

7. The embossing-laminating device according to claim 1 , wherein the first manipulator comprises opposed support members of a respective interchangeable embossing roller, which engage with respective ends of the respective interchangeable embossing roller to take the respective interchangeable embossing roller and release the respective interchangeable embossing roller in the magazine, and vice-versa.

8. The embossing-laminating device according to claim 1 , wherein the first manipulator is arranged and configured to manipulate and replace the first interchangeable embossing roller and the second interchangeable embossing roller with respective interchangeable embossing rollers contained in the magazine.

9. The embossing-laminating device according to claim 1 , wherein the first manipulator comprises an elevator movable between a first height, at which the first interchangeable embossing roller or the second interchangeable embossing roller is located, and a second height, lower than the first height, at which the magazine is located.

10. The embossing-laminating device according to claim 1 , wherein the magazine is located at a lower height with respect to the first interchangeable embossing roller and to the second interchangeable embossing roller and with respect to the first pressure roller and to the second pressure roller.

11. The embossing-laminating device according to claim 1 , wherein the magazine comprises a plurality of seats movable orthogonally to axes of the first interchangeable embossing roller and of the second interchangeable embossing roller with a translational movement in a substantially horizontal direction.

12. The embossing-laminating device according to claim 1 , wherein the first manipulator is provided with a lifting and lowering movement between a lower position, at which the magazine is located, and one or more higher positions at which the first interchangeable embossing roller or the second interchangeable embossing roller is located, and wherein the first manipulator is provided with a movement toward or away from the first interchangeable embossing roller or the second interchangeable embossing roller, the movement toward or away from being a translational movement substantially transverse with respect to the lifting and lowering movement.

13. The embossing-laminating device according to claim 1 , wherein the first interchangeable embossing roller along the first path and the second interchangeable embossing roller along the second path are rotatingly constrained to the load bearing structure by reversible constraining members, configured to disengage a respective interchangeable embossing roller and allow removal thereof by the manipulator and replacement thereof with an interchangeable embossing roller taken and transferred from the magazine by said manipulator.

14. The embossing-laminating device according to claim 13 , wherein the reversible constraining members comprise, for each interchangeable embossing roller, a pair of openable seats, into which support bearings for a respective interchangeable embossing roller are inserted, and wherein each openable seat comprises an actuator for controlling opening and closing of the openable seat.

15. The embossing-laminating device according claim 1 , wherein each interchangeable embossing roller is associated with a transmission for rotary movement from a motorization device, said transmission being configured to allow removal of the interchangeable embossing roller and replacement thereof with another interchangeable embossing roller taken from the magazine by a movement of the interchangeable embossing roller in a direction orthogonal to a rotation axis of the interchangeable embossing roller.
