A welding device has two mutually engaging welding wheels, together with a separating device having a blade with a cutting edge. Two film webs can be welded together in conventional manner using the welding device. The blade is able to separate a projecting length from the welded film, the blade being heated. Heating takes place by a heat bridge, which connects the blade to a heater of the welding device. This economizes a separate heater for the blade.
