Abstract
PURPOSE: To improve the rolling rate with a shorter wrapping time by controlling the timing for retreating a belt wrapper according to the thickness of the strip wheel in wrapping a tension reel therewith.
CONSTITUTION: As the tip of a strip passes the position of a thickness gauge, a switch controlling circuit 14 outputs a change-over signal Si according to an inputted thickness to turn on a switch 131 while all other switches are off. When the tip reaches the position of a steel piece detector 10 passing a bridle roll 1, a shear controller 7 gets and counts the output of a pulse generator 9 to initiate calculation of the timing for starting a shear 2. As the tip of the strip reaches the intended position, it is cut off with the driving of a motor 6 in response to a shear driving signal by the shear controller 7. On the other hand, a comparator 121 provides an output to a valve driving circuit 15 according to the thickness to drive a hydraulic valve 16 thereby retreating a belt wrapper 5.
