Patent

CA 2100797

There is disclosed a rewinding machine for the production of logs(R) of web material (N) without central winding core. It comprises a first winder roller (11) around which the webmaterial is driven and a second winder roller (13) defining, with the first winder roller, a nip (14) through which the web material passes. A member (21) is also provided which is movable relative to the first winder roller (11) and which is cyclically moved toward the surface of said first winder roller with the web (N) between the member (21) and the roller (11) in order to pinch and thus brake the web material between said member (21) and the first winder roller (11), thereby tearing the web and causing the free edge generated by the interruption of the web material to start winding up on itself.
