ABSTRACT:
A drum support arm supports a cutting drum with a sector cross section and a receiving drum with a circular cross section, and moves between a web winding changeover position for causing the receiving drum to contact a core and a spacing position for keeping the receiving drum away from the core. The guide roller moves between an approaching position for lifting a web from the receiving drum and a retracted position for causing the web contact a peripheral surface of the receiving drum. When the drum support arm moves to the web winding changeover position, the guide roller moves to the retracted position, and when the drum support arm moves to the spacing position, the guide roller moves to the approaching position. When the drum support arm is set to the web winding changeover position, the cutting drum rotates once to cut the web. A front end of the web formed by cutting is pressed against the core by the receiving drum and wound around the periphery of the core.
