ABSTRACT:
A continuous winding device for webs of paper, such as toilet paper, comprises a first drum which is drivable at a peripheral speed equal to the speed at which the material to be wound is fed during the winding phase, and a second drum spaced from the first by a distance corresponding to the diameter of winding cores for the formation of spools of the material. The second drum is driven at a peripheral speed equal to that of the first, and to that of the material being guided along the second drum. A mechanism for temporarily varying the speed of the first drum during a phase of core replacement and for tearing the material is provided as is a mechanism for inserting a core between the two drums. A displaceable presser drum is also used which bears against the spool being formed and thus holds the spool between the two first and second drums and the presser drum during winding. The device includes, the first drum, annular seats with perforated zones, for receiving suction orifices adapted to exert a suction force during the removal of the finished roll and insertion of a new core. The material is thus brought to the zone in which the tearing is to take place, and the material is securely inserted between the drum and the new core.
