ABSTRACT:
A winding rod is mounted for rotation in winding and unwinding directions about a fixed axis of rotation. An elongated flexible member has one end affixed to the winding rod. A traction device is operatively connected to the flexible member for selectively pulling the flexible member at a predetermined speed in the winding and unwinding directions. A first driving device is rotatable in normal and reverse directions and includes a torque motor for driving the winding rod. A clutch operatively couples the driving device to the winding rod and is maintained in a disengaged state during the unwinding operation of the winding rod by making the speed of rotation of the driving device in the reverse direction higher than the speed of rotation of the winding rod in the unwinding direction.
