ABSTRACT:
In order to simplify the construction and to accelerate the change-over of two drive units in the case of a feeding device having a drive shaft and two gear units each drivable by a motor, which gear units are able to be connected alternately to the drive shaft such that each may alternately rotate with the drive shaft independently of the other, it is suggested that both gear units are designed as slip-on gear units and have a driven hollow shaft, that the two ends of the drive shaft each have the hollow shaft of one of the two slip-on gear units mounted around them in a manner permitting relative rotation, that the gear units are secured against rotation about the axis of rotation defined by the drive shaft and that rotary couples are provided, such that one of the hollow shafts at a time is connected to the drive shaft such that the connected hollow shaft secured against rotation relative to the drive shaft.
