Abstract
One of the two knife holder shafts in a cross cutter for webs of paper or the like is driven by a unit wherein a motor rotates the input shaft of a bevel gear drive whose output shaft drives or constitutes one shaft of a universal joint. The other shaft of the universal joint is driven by the one shaft and transmits torque to the knife holder shaft or shafts by way of a step-up gear transmission and a clutch which allows for changes in angular positions of the knife holder shafts with reference to the universal joint. An extension of the axis of the input shaft of the bevel gear drive intersects the axes of the shafts of the universal joint at the point where the axes of the shafts of the universal joint intersect each other. To this end, the other shaft of the universal joint contains an elastically deformable but torsion-resistant insert. The angle between the axes of the shafts in the universal joint can be changed by a carrier which is turnable about the axis of the input shaft of the bevel gear drive and rotatably supports the one shaft of the universal joint.
