摘要： PURPOSE:To exchange rolls easily and rapidly by slacking a strip wrapped around the rolls and moving the rolls in their axial directions by providing a device for holding the slacked strip. CONSTITUTION:A strip S is held between rolls 3, 4 by pushing upward and downward roll chocks 5, 6 respectively with the aids of hydraulic pistons. Next, a roll gap is formed between rolls 7, 3 by moving upward roll chocks 9, 13 in one body, and in the same manner, a gap is also formed between rolls 4, 8. The strip S is slacked at the wrapping parts of rolls 3, 4 when pinch rolls 17, 18 are moved slightly to the downstream and upstream sides, and the wrapping parts of strip S are held by the attraction device 21 of a holding device 19. By this mechanism, the work rolls 3, 4 are easily extracted in their axial directions without being interfered with the strip S.

摘要： PURPOSE:To prevent fluctuation of tention by correcting the torque command in accordance to the torque correction amount to be set with correspondence to the differential speed of motors for performing roll control at the inlet side and the processing side then controlling the motor for loop car on the basis of said correction command. CONSTITUTION:When feeding an iron plate 10 to be processed through rewind reel 1, bridle rolls 2, 3 and loop car 4 to the processing section, the difference between the speed commands v1c, v2c of motors 2A, 3A for each bridle roll 2, 3 and the speeds detected through speed detectors 2E, 3F will appear as the load torque variation of motor 29 for loop car. The speed vL of loop car 4 is followed by tension correcting circuit 45 with correspondence to said differential speed. In other word, the difference between a torque command and required torque is operated then the torque produced from motor 4C for loop car 4 will follow the required torque thus to eliminate fluctuation of tension to be applied onto the iron board 10.

摘要： PURPOSE:To pass smoothly a strip without causing buckling and roll impression while controlling a strip tension and to prevent the lowering of its quality by arranging tension-controlling devices near the inlet and outlet sides of a device used for changing the advancing direction of strip, where plural guide rolls are arranged on the plural imaginary curved lines formed spirally along an imaginary conical or cylindrical surface. CONSTITUTION:As a tension controlling device, tension bridles 15, 16 consisting of plural rolls 15a, 16a are arranged respectively at the inlet and outlet sides of an advancing-direction changing device 11 by bringing them closer to the device 11. The range of the tension of a steel strip 3, on the way of passing the device 11 is controlled so that the strip 3 is smoothly passed without causing buckling by contact with guide rolls provided to the path and generating roll impression.

CONSTITUTION:A speed control device comprises speed reference circuits 11, 12 for respectively controlling the outlet and inlet speeds VD, VE of a loop car which handles a steel plate or the like, measuring circuits 13, 14 for measuring the speeds VD, VE, a measuring circuit 15 for measuring the position of the loop car and a setting circuit 17 for setting the rate alpha of acceleration or deceleration. The synchronous position of the loop car is controlled by means of a control circuit 16 in accordance with output signals from the above-mentioned measuring circuits 13 through 15. Further, a computing circuit 21 for computing the speeds VD, VE and the rate alpha of deceleration or acceleration, on the inlet side, for introducing the loop car from the actual position thereof to the synchronous position thereof, is provided downstream of the control circuit 16. Further, there is provided a selecting circuit 22 for controlling the change-over of switches 22a, 22b to obtain the synchronous position.
