Abstract (en)
[origin: JPH0568906A] PURPOSE: To prevent strips from being caught by a roller at the time of cutting a flat material to the strips. CONSTITUTION: A cutting mechanism 11 for torsion cut has two cutting rollers 12, 13. Respective cutting disks 14, 15 have a steep cutting face 22 and a sloping back face 23 in each case. The transitions between the sloping back face 23 and a roller body 16 are generously filleted. Ratios between the cutting disk spacing, height, etc., are such that an opening 29 for the cut strips 28 has a compact and well rounded shape so that the cut strips 28 do not tend to get caught at the opening 29.
