Abstract
PURPOSE: To operate the feed-in side at fixed speed and decrease the quantity of slack by a method wherein a preference circuit is formed, and length measuring counter output is prefered when the delivery side is decelerated or stopped and deviation counter output after delivery is started respectively.
CONSTITUTION: A deviation counter 12' counting deviation between the quantity of feed-in and the quantity of delivery by obtaining the output of pulse generators 7, 7', a DA converter 13', a preference circuit 14' putting out the smaller side when comparing the output of DA converters 10' and 13', and a speed setter 15 are mounted to a slack quantity limiting device. During a period when the delivery side is decelerated or stopped, the preference circuit 14' puts out the output of a length measuring counter 9' preferably, and after delivery is started it puts out the output of the deviation counter 12' preferably because the output of the length measuring counter 9' becomes larger. The output of the deviation counter 12' decreases until delivery speed equalizes with feed-in speed, a fixed quantity condition is brought, the feed-in side is brought to a fixed speed condition and the quantity of slack is controlled and reduced.
