摘要

A rewinding machine for the production of logs (R) of web material (N) without a core comprises: a first winding roller (1) onto which the web material is fed; a second winding roller (3) rotating in the same direction as the first roller and forming a nip (4) therewith through which the web material passes; means (15, 17) to move the surface of said second winding roller (3) toward said first winding roller (1); and means to sever said web material at the end of the winding thereof to for a log (R). Provision is also made for a surface (21, 21A) supporting the log (R2) in the process of formation and located upstream of the nip (4) between said rollers (1, 3). IMAGE
