Claim:
Method for manufacturing an interchangeable sleeve of a cylinder for processing a web-like material, having an external processing surface, comprising: providing a non-cylindrical central core having a cross-section with dimensions gradually increasing from an end with a smaller cross-section to an end with a greater cross-section; fitting onto said core a jacket having a substantially cylindrical external surface and an internal surface, leaving an interstice between the internal surface of said jacket and an external surface of said core, centering said jacket and said core relative to each other; introducing a substantially fluid hardening resin material into said interstice so as to form a layer of hardened resin material fixed to the internal surface of said jacket, said jacket and said layer of hardened material forming said sleeve; extracting axially with respect to each other said jacket, with the layer of hardened material adhering to the jacket, and said core.
