The machine comprises: a spindle (1); a winding unit (5), cooperating with the spindle to wind one or more strips of web material about the spindle and form a tubular element (T); a cutting unit (31) with at least one discoidal cutting tool to divide the tubular element into tubes of a length which can be predetermined. At least one pressure element is associated with the cutting tool, to compress the tubular element between the spindle (1) and the pressure element adjacent to the cut performed by the cutting tool.

The device for joining at least two plies of paper (V1 , V2), in particular tissue paper, comprises a ply-bonding unit (9) and moistening means (11) to moisten at least one of said two plies before joining.
摘要:
The interchangeable sleeve comprises: a substantially cylindrical outer surface (105A); a layer of hardened resin (R); a substantially conical inner surface for connection to a conical central core of the roller. The inner surface is formed at least partially of at least one inner component (102) having greater rigidity than said hardened resin. The inner component is constrained to the sleeve by means of said hardened resin.

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).
