Is a looper speed controller, 23 is a looper speed detector, and 24 is a looper tension controller. The speed of the entrance bridle 1 is controlled in accordance with the speed command of the entry speed command generator 6. The same applies to the outlet bridle 2. Further, the looper 3 is tension-controlled and speed-controlled by a minor loop thereof, and the speed command is given a deviation between the speed commands on the input side and the output side. The output of the looper tension controller 24 is input to this speed loop. The looper 3 is installed between the entrance where the processing cannot be interrupted, that is, the transportation of the material cannot be stopped, and the exit where the transportation must be stopped to exchange the product. In some cases, the entrance side and the exit side are opposite, that is, the facility may not be able to stop the exit side. While the delivery side is stopped, the looper 3 accumulates the material while maintaining the predetermined tension, and waits for the processing on the delivery side. When the product is exchanged, that is, the wound product is paid out and the preparation for the winding of the next product is completed, the output side pays out the accumulated amount at a higher speed than the input side, and at the predetermined position, has the same speed as the input side. At this time, the speed of the looper 3 becomes zero. That is, the tension control is performed in the stopped state.

張力制御を行える装置を提供することを目的とする。When the tension control is performed in the above-mentioned looper 3 in a stopped state, if the speed control gain during traveling is maintained, a speed control output to respond to a minute speed deviation is generated. Vibration occurs near the stop position. In particular, when the looper 3 is moved up and down by a loose chain or a rope having a large elongation, the system may be disturbed and the material may be broken. Further, when the tension control is performed by the detector on the entrance side (or the exit side) of the looper 3,
The outlet (or inlet) tension is not controlled and the looper 3
The material expands and contracts due to mechanical loss of itself and many non-driving rolls and acceleration / deceleration torque due to their inertia, and the looper is inclined. As described above, according to the related art, there is a problem that the tension control of the transport material in the looper becomes unstable. An object of the present invention is to provide a device capable of solving this problem and performing stable tension control.
