    Abstract: The rotating cylinder comprises: an elongated inner core (12) which is substantially rigid and an interchangeable sleeve (45) which is fitted onto the core; the sleeve is axially and angularly constrained to said core and is provided on its external surface with a raised pattern. The internal surface of the interchangeable sleeve and the external surface of the inner core are conical surfaces which are mutually complementary; axial and angular locking of the interchangeable sleeve and the inner core is achieved by the friction between the conical surfaces which are forced axially one onto the other.

    Abstract: The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g/m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions/cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).

    Abstract: A method of forming a multi-ply web by embossing a first ply between a first pair of matched embossing rolls including a first embossing roll having protuberances formed in a substantially rigid outer surface and a second embossing roll having protuberances formed of a resilient material thereby forming raised portions and recessed portions in the first ply, embossing a second ply between a second pair of matched embossing rolls including a third roll having protuberances formed in an outer surface formed of a resilient material and a fourth roll having protuberances formed in a substantially rigid outer surface thereby forming raised portions and recessed portions in the second ply with the first and second pairs of matched embossing rolls being positioned such that the first embossing roll is positioned adjacent the third embossing roll forming a nip region between the respective protuberances formed in each roll. An first adhesive is then applied to the web carried by the third adhesive roll with the first ply and second ply being adhered to one another in the nip region wherein the raised portions of the first and second plies are adhered to one another and the recessed portions of the first and second plies are spaced from one another.
