Abstract
A cutting mechanism (11) for torsion cut has two cutting rollers (12, 13), cutting disks (14, 15), which in each case have a steep cutting face (22) and a sloping back face (23). The transitions between the latter and the roller body are generously filleted and the ratios between the cutting disk spacing, height, etc. are such that the opening (29) for the cut strips (28) has a compact and well rounded shape, so that the strips do not tend to get caught.
