ABSTRACT:
A continuous log roll winder cuts and transfers on the fly without stopping the winding process. The web passes around a rotating drum with the adhesive side out and travels to a wind-up spindle. A knife cuts the web against the surface of the drum. By heating the knife to temperatures above 300.degree. F., the web and adhesive does not stick to the knife; the adhesive does not accumulate on the knife; and the adhesive does not transfer through the cut in the web backing and deposit on the rotating drum.
