Abstract
The driving gear meshes with the gear on the web of a planetary gear. This planetary gear includes an arrestable sun wheel. The output sun wheel is rigidly connected to the drive shaft. It extends through a sleeve section of the web. A longitudinally displaceable shifting sleeve is located on the sleeve section, which shifting sleeve has a plurality of control disks. These control disks control via a roller the rocking movement of the upper feeding roller. Accordingly, the period of the rocking movement can be selected depending on a respective selected control disk. If the sun wheel is unlocked, the shifting sleeve may be moved such that it engages directly the drive shaft such that by properly selecting the number of teeth, it is possible to choose between a rotational speed transmission relation of 1:2 and 1:1.
