Abstract

A cross cutter for a running web of paper which is transported along a horizontal path has an upper rotary knife holder above and a lower rotary knife holder below the horizontal path. The holders carry knives which extend transversely of the path, and each holder further carries an elastic lip-shaped deflector which is located behind the respective knife and serves to maintain the leader of the web behind the separated length of the web in or close to the path so that the leader can enter a transporting unit which advances the severed lengths of the web to a stacking or other processing station. The lower deflector is installed immediately behind and the upper deflector is spaced apart from the rear side of the respective knife.
