ABSTRACT:
The present invention generally relates to severing a running material web in a folding apparatus of a web-fed rotary printing press. In one exemplary embodiment, a severing element is moved in the traveling direction of the web with a speed which is substantially equal to the speed of the running web and is simultaneously moved across the width of the web in a substantially lateral direction. The severing element can be a sled with a blade, a laser source, a high-pressure fluid jet or a heated wire. The severing element is received and guided by a guiding rail coupled to a pair of endless parallel transport chains.
