PURPOSE:To eliminate the driving unit of a winding drum shaft such as, fore placing gearing, a motor, etc. to simplify driving system and make the entire device compact by incorporating plural motors which directly drive plural winding drums respectively, in a machine body. CONSTITUTION:Each of winding drum shafts 39a, 39b can be directly rotated independently and at a desired speed of rotation, by exciting the windings of motors 43a, 43b and applying voltage to armatures 41a, 41b. Apart from the rotation of the winding drum shafts 39a, 39b, on the other hand, a machine body 31 is rotated by means of a driving motor 36 for revolution, to carry out the revolution of the winding drum shafts 39a, 39b. All the rotations of the machine body 31 and the winding drums 39a, 39b can be carried out independently and, accordingly, the machine body 31 can be rotated while carrying out winding or unwinding by rotating one winding drum shaft 39a, or 39b, to make the winding drum shaft 39a, 39b revolve, enabling changeover to one winding drum shaft 29b, or 39a. Thus, the driving system can be simplified making the whole unit compact. |
