ABSTRACT:
A device for driving two winding drum shafts which are rotatably supported by the body of a coiler or un-coiler that acts to wind or unwind rolled material. A casing constituting a ring gear frame is disposed at the center of the body, which is revolved in a circle. Two ring gears each of which has external teeth and internal teeth are rotatably held to the casing. Two pinions mate with the internal teeth of these two ring gears. Two motors are provided to drive their respective drum shafts. When rotatory motion produced by each of these motors is transmitted to the drum shafts via the ring gear mechanisms, the mating engagement of the pinions with the ring gears results in a high reduction gear ratio. Another motor is also provided to revolve the body of the machine in a circle.
