Abstract
A conveyor surface for carrying off separated sheets in a web welding and separating machine is displaced from a welding gap between a welding roller having a welding tool and an opposing roller in the direction of the axis of the opposing roller. As the leading edge of a thin web passes beyond the welding gap, it tends to stay close to the surface of the opposing roller until it has been borne a substantial circumferential distance past the welding gap, whereupon it separates therefrom. A guide plate bridges a space between the opposing roller and the conveyor surface to smoothly transfer the separated sheets to the conveyor surface. An elastically compressible strip on the welding roller is optionally used to improve the separation of the leading edge of the web from the welding tool and to closely press it against the opposing roller.
