The embosser includes two load-bearing structures that are mutually movable to approach and move away from each other. The first load-bearing structure supports a plurality of first embossing rollers that can be selectively brought to an operating position, in which they cooperate with a first pressure roller. The second load-bearing structure supports one or more second embossing rollers cooperating with a second pressure roller. The two support structures can be moved away from each other to allow the selection movement of the first embossing rollers.

Multiple roller embosser and method for selecting an embossing roller

Perforating device for perforating a web material including a first blade-holder adapted to rotate around a respective first rotation axis and on which at least a first perforating blade is mounted; and a support beam, on which a plurality of counter-blades are mounted; the support beam being angularly adjustable around a selection rotation axis thereof in a plurality of angular working positions, in each angular working position one of the counter-blades being in an operative position. A movable abutment is provided adapted to co-act with the support beam. A first actuating device is provided for moving the movable abutment between an active position, where the movable abutment co-acts with the support beam, and an idle position, where the movable abutment is spaced from the support beam. A second actuating device is provided for rotating the support beam in order to arrange it selectively in one of the angular working positions.

Perforating device and converting machine comprising said device

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.

Magazine for embossing rollers and embossing device comprising the magazine

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.

Embossing-laminating device

The embossing unit includes in combination: a first support for a first embossing roller and a second support for a first pressure roller, cooperating with the first embossing roller. The second support presents two seats to receive and support the first pressure roller in two different positions with respect to this support. The embossing unit also includes a third support for a second embossing roller. The third support can take at least two different operating positions. A fourth support is provided to support a second pressure roller suitable to cooperate with the second embossing roller and suitable to take at least an operating position and an idle position. Finally, there is provided a fifth support with a double seat to receive and support in two different positions alternatively a marrying roll or the second pressure roller.
