(54) Web winding system


(57) A web winding system for winding adhesive backed web on cores mounted on wind-up spindles. The web is supported on a rotating suction drum. A knife mounted on a rotating wheel cuts the web against the supporting drum. A tab bar is mounted on the wheel adjacent to the knife, and applies a tab to the web in registration with the cut. In a second position of the wheel a tab source moves toward the tab bar and applies a tab to its surface. The knife is heated by a heater to a temperature above adhesive softening and below adhesive carbonizing to prevent adhesive to stick to or to accumulate on the knife.
