摘要：PURPOSE:To let loop changing be smoothly and stably accomplished by applying signal directly to the loop tting part to t the loop in the specified position at the time of changing the loop and letting a potentiometer follow up this thereby tting a reference loop position. CONSTITUTION:When a loop part 5 becomes excessive, an operation switch 26 is operated to the loop small side. Then, a manual relay 27 goes ON to apply voltage to a limiter 41. The output thereof is directly applied to an operational amplifier 24 which in turn increas the speed of a correcting motor 15 and increa the speed of a roller 7. The loop 5 then becomes smaller. On the other hand, when the manual relay 27 goes ON, the output voltage of a guide amplifier 23 is applied to a rvo motor 30 to cau a potentiometer 22 to move. The output of the potentiometer 22 is applied to a preamplifier 20 and subtraction is effected between the voltages detected. The output of the web guide amplifier 23 is supplied to the motor 30. This beedback operation caus the potentiometer 22 to be ret in the t position suited for the size of the pret loop 5.
