Abstract
PURPOSE: In a winder control apparatus of a paper machine, to improve lag of response and avoid slack of paper, which causes breakage of paper by torque compensation according to GD2 value of winding and rewinding sides.
CONSTITUTION: Repair work on a strip material is carried out when winding is temporarily stopped, and its tension is kept constant until winding is restarted. An arithmetic unit 26 is adapted to find a time tw till a stop by diameter of a take-up roll, winding speed, tension, correcting torque, diameter of a shaft, GD2 value of a motor and mechanical loss. A comparator 28 is adapated to find a time tμw till a stop by rotational frequency of a rewinding roll, winding speed and quantity of correction β. The difference t therebetween is found by the comparator 28. If Δt> 0, it is quantity of correction α through an integrator 29 and a diode 31, and if Δt<0, it is quantity of correction β through a diode 31a. Mechanical loss torques Tm1, Tm2 are corrected in such a manner as to stop for the same time by each quantity of correction α, β.
