ABSTRACT:
Apparatus and method for joining, while stationary, an expiring web to a new web in such a way that the joined webs lie in one plane. To this end, the new web and the expiring web are brought together and are simultaneously cut through along one cutting line. Subsequently, at least on one side, a bonding strip is applied over the web parts to be joined. The beam-shaped unit has a first contact surface for the new web. In line therewith and on the same side of the travel path, a second contact surface is arranged for the expiring web. That part of the new web which is located downstream of the cutting line, is situated at a distance from the expiring web. By retaining each of the web parts to be joined against an associated contact surface, it is possible to achieve an accurate join.
