Abstract
The rewinding machine includes a first winding roller; a second winding roller; a nip defined between the first and second winding rollers, through which the web material is fed; a roller surface, extending upstream of the nip in relation to the direction of feed of the web material and defining, with the first winding roller, a channel into which winding cores are fed, the channel having an inlet and an outlet; a feeder to feed winding cores into the channel; and a severing device to sever 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 the channel, in relation to the direction of feed of the web material. The first winding roller has suction openings on its cylindrical surface. Moreover, between the position in which the severing device operates and the inlet of the channel, a suction box is provided inside the first winding roller.
