ABSTRACT:
A film web handling mechanism includes a motor for driving the mechanism, and an endless belt for transferring the motor drive to a supply pulley, a take-up pulley and a shuttle-shuttle drive pulley. The supply pulley and the take-up pulley are connected, through a supply clutch and a take-up clutch, to a supply spindle and a take-up spindle. The endless belt is driven in one direction only by the motor, however, the supply and take-up spindles are capable of moving the film web in both a forward and reverse direction. The forward and reverse direction capability of the supply and take-up spindles is accomplished by varying the amount of motor drive transferred to the spindles through the clutches. By means of a single control knob linked to the supply clutch and to the take-up clutch, an operator is able to select a mode of operation.
