Abstract

PURPOSE:To shorten the size in the axial direction of the device and to form a compact looper device by incorporating the motor to drive the looper main body to the rotary part of the looper main body. CONSTITUTION:On a motor 15 a stator 21 is firmly held by a shaft supporter 16 and a rotor 22 is rotated integrally with the main body of a looper 13. With the electrification of the motor 15, therefore, a rotary force is generated between the stator 21 and rotor 22, the looper main body 13 integrated with the rotor 22 is rotated and a looper roll 14 comes into contact with the rolling stock. In this case the rotary force of the motor 15 is increased and decreased by controlling the input to the motor 15 to control the tension of the rolling stock.

た。In the conventional looper device, as shown in FIG. 3, the looper main body (3) and the looper driving electric motor +51 are arranged between the rolling roll stands (2), so that the arrangement thereof becomes cramped. In particular, because it is arranged between the looper drive motor (5) and the reduction gear for driving the rolling rolls (not shown), due to dimensional constraints,
This required a special elongated shape, making it expensive. Furthermore, daily maintenance and inspection has become extremely difficult.
