Abstract

PURPOSE: To control the leveller readily and inexpensively by so controlling the leveller that the respective armature currents of a payoff reel 1 and a tension reel become constant with consideration being also paid for mechanical loss differences before and behind the leveller and the section driven by a moter, such as side trimmer.
CONSTITUTION: A payoff reel 1 is let to follow up winding coiling diameters through counter electromotive voltage control of field systerm and is subjected to constant tension control through constant current control of armature current. A tension reel 7 is also subjected to coiling diameter control by field potential as well as to constant speed control through feedback of armature voltage to be acted as a minor loop. A fine leveller 4 controls the back tension of the payoff reel 1 and the tension of the tension reel 7 so as to become equal by a correcting speed commander X by taking the mechanical loss difference before and behind the leveller and the effect of side trimmer 3, etc. into consideration as well, besides the speed command of a general line as its speed command.
