(FR) MACHINE DE REMBOBINAGE
Abstract
(DE) Rewinding machine comprising a drive unit (1) for supplying a paper veil (2); a winding unit (3) for winding the paper veil supplied by the drive unit into a coil (W) around a winding core (4), comprising a primary roller (6) and a secondary roller (7) rotating in contact with the winding core (4), and a pressure unit (30) provided with a rotating roller (A, B, C) on the coil (W) that is being formed; a core exchange unit (5) for ejecting the formed coil (W) from the machine at the end of a winding cycle and inserting a new core to be wound; separation means (11) for interrupting the continuity of the paper veil at the end of a winding cycle; means for winding a drawing flap (34) of the veil (2) on the new core (4) at the beginning of a new winding cycle.
