Abstract

A system for joining the end of a web of material (4) running off a first winding roll (17) with the beginning of a web on a new winding roll (1) interchanged with the first winding roll (17) on an unwinding machine comprising devices for cutting through the web (4) being wound off, for holding the end of the web so produced, and for pressing the end of the web against the periphery of an interchanged new winding roll (1), in order to produce an adhesive bond, has a splice element (6) which can be placed on the web being wound off (4), moved beyond the region of a full winding roll (1) and pressed against its periphery. The splice element (6) contains a web cutting element (15) and a holding element (16) which, when placed in contact with the web being wound off (4), is located behind the web-cutting element (15) in the direction of motion of the web.
