Abstract:
The cellulose product comprises at least a first ply of embossed cellulose material and a second ply of embossed cellulose material, glued together. The first ply comprises: a first series of embossing protuberances with a first height (Η'1) and a top surface to which a glue is applied which bonds the first ply and the second ply to one another; a second series of micro-embossing protuberances with a second height (H'2) lower than the first height (H'1); a third series of micro-embossing protuberances with a third height (H'3) lower than the second height (H'2). The protuberances of the first series are distributed over areas of the first ply, where the micro-embossing protuberances of the second series and the micro-embossing protuberances of the third series are absent.

Abstract:
The present invention concerns a packing machine (1) in which sealed packages are formed from a packaging material web (2) and a method of processing the packaging material web (2). The packing machine (1) has embossment means placed in or below an aseptic chamber (8) and above a product level (76). Before embossing the packaging material web (2) is heated to a temperature of at least 60 0C. The heating normally takes place in an aseptic chamber (8). After the embossing the packaging material web (2) is cooled to about 20 0C. The cooling is normally given by means of the product to be filled in the sealed packages.
Abstract:
The embossing unit comprises in combination: a first support for a first embossing roller (7) and a second support for a first pressure roller (11), cooperating with the first embossing roller (7). The second support (9) presents two seats (9A, 9B) to receive and support the first pressure roller (11) in two different positions with respect to this support. The embossing unit also comprises a third support (19) for a second embossing roller (17). The third support can take at least two different operating positions. A fourth support (33) is provided to support a second pressure roller (35) suitable to cooperate with the second embossing roller (17) and suitable to take at least an operating position and an idle position. Finally, there is provided a fifth support (51) with a double seat to receive and support in two different positions alternatively a marrying roll or the second pressure roller (33).
Abstract:
The device comprises: a first embossing unit (3) with a first embossing roller (5) equipped with a first series of protuberances (5P); a second embossing unit (13) with a second embossing roller (15) equipped with a second series of protuberances (15P) of greater height and lesser density with respect to the protuberances of said first series, said protuberances defining decorative motifs; a glue dispenser (19) associated with said second embossing roller, to apply a glue to a first ply (V1) embossed by said first and said second embossing unit at the protuberances of said second embossing roller; a laminating member (21) associated with said second embossing roller to apply a second ply (V2) to the first ply. At Ieast a printing unit (9), which applies an ink to said first ply (V1) at the protuberances of the first embossing roller, is associated with the first embossing roller (5).
