Abstract
A surface winder includes first and second winding rolls for winding a web on a center member, a stationary surface spaced from the first winding roll for rolling a center member on the stationary surface, and a pinch pad for pinching the web against a pinch surface upstream of the center member and thereby severing the web. The first winding roll is provided with a high friction surface, and only a short length of web needs to be stretched between the pinch surface and the first roll to tension and sever the web. The severed web is wound on the center member as the center member rolls on the stationary surface.
