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 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.
