Abstract

The device has a rotating drum (12) for supporting a screw (14), and a driving motor coupled to the drum to actuate the drum. A screw driving motor comprises a housing that is permanently fixed to the drum to rotate with the motor. A torque motor is mounted in the housing and rotatably coupled to the screw, where the torque and drum driving motors are disconnected from one another.
