ABSTRACT:
For loading a processing machine with band-like material from a coil, a rotatable support, on which the coil rests with its axis substantially vertical, is driven by a motor. Since the circumference of the coil decreases during unwinding, a sensor is provided for controlling the motor to maintain a desired constant band speed.
