The rewinding machine comprises: a first winding roller (1); a second winding roller (3); a nip (5) defined between said first and said second winding roller, through which said web material (7) is fed; a roller surface, extending upstream of said nip in relation to the direction of feed of the web material and defining, with the first winding roller (1), a channel into which winding cores are fed, said channel having an inlet (9) and an outlet (11); a feeder (13) to feed winding cores into said channel; a severing device to severe the web material upon termination of winding a log. The severing device is disposed to operate on the web material in a position upstream of the inlet end of said channel, in relation to the direction of feed of the web material and the first winding roller has suction openings on its cylindrical surface. Moreover, between the position in which said severing device operates and the inlet of said channel a suction box (17) is provided inside said first winding roller.

Cette machine à enrouler comprend: un premier cylindre enrouleur (1); un deuxième cylindre enrouleur (3); un écartement (5) défini entre le premier et deuxième cylindre enrouleur et par lequel on alimente le matériau en bande (7); une surface de cylindre, remontant depuis l'écartement par rapport au sens de passage du matériau en bande et définissant, avec le premier cylindre enrouleur (1), un canal dans lequel sont amenés les mandrins d'enroulement, lequel canal comporte un orifice d'entrée (9) et un orifice de sortie (11); un introducteur (13) amenant les mandrins d'enroulement dans le canal; et un dispositif de coupe pour couper la bande de matériau une fois le rondin enroulé. Le dispositif de coupe et disposé de façon à agir sur le matériau en bande en une position en amont de l'extrémité d'entrée dudit canal par rapport au sens de progression (f7) du matériau en bande, la surface cylindrique du premier cylindre enrouleur étant pourvue d'orifices d'aspiration. En outre, entre la position dans laquelle agit le dispositif de coupe et l'orifice d'entrée dudit canal, se trouve un caisson d'aspiration (17) ménagé à l'intérieur du premier cylindre d'enroulement.
