Abstract: An embossing device (1) includes three embossing rollers (5, 7, 9), each co-acting with a pressure roller (11, 15, 19), to emboss a plurality of paper plies (V1, V2, V3). Two embossing rollers can be easily interchanged to switch from a nested configuration to a tip-to-tip configuration, or to switch from one type of pattern to another. A lamination roller and a glue dispenser are arranged around one of the embossing rollers.

Abstract: An interfolding machine (1) is described, including folding rollers (3). Such a roller has a cylindrical sleeve (3C) having a rotation axis (3A), an outer surface (3X) and an inner surface (3Y) defining an inner axial cavity (23) of the cylindrical sleeve (3C). The cylindrical sleeve includes, furthermore, a plurality of suction holes (41, 43) which extend from the outer surface (3X) to the inner surface (3Y) of the cylindrical sleeve (3C). The suction holes are arranged depending on longitudinal alignments (42, 44), parallel to the rotation axis (3A) of the cylindrical sleeve (3C) and angularly staggered in relation to one another. Inside a suction chamber (23A) in the cylindrical sleeve (3C), shutters are stationarily arranged having closing surfaces (37A) cooperating with the inner surface (3Y) of the cylindrical sleeve (3C) to selectively close the suction holes.
