Abstract
Shears for dividing and cropping rod-shaped work material (18) which is moving in the longitudinal direction, have two paraxial blade shafts (3) driven in opposite directions, a blade holder (1,2) having at least one blade (6, 7) being rigidly secured to each of said shafts. The cutting edges (14, 15) of the blade project beyond the blade holders and orbit along two circular paths (16, 17) which overlap slightly. In order to prevent, when using this type of shears, the following longitudinal section being bent following cutting, the two blade clearance angles (.beta., .gamma..sub.1) upstream of the cutting edges (14, 15) at the entry side are equal and the two blade clearance angles (.beta..sub.1,.gamma.) downstream of the cutting edges at the delivery side are also the same size.
