Abstract
PURPOSE: To let loop changing be smoothly and stably accomplished by applying signal directly to the loop setting part to set the loop in the specified position at the time of changing the loop and letting a potentiometer follow up this thereby setting 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 increases the speed of a correcting motor 15 and increase 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 servo motor 30 to cause 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 causes the potentiometer 22 to be reset in the set position suited for the size of the preset loop 5.
