ABSTRACT:
A takeup motion control device for a loom includes an input setting unit for producing functions of a repetitive period and a takeup speed, a function generator for storing the functions in relation to r.p.m. of the loom, an arithmetic control unit for successively reading out the selected functions from the function generator in synchronism with rotation of the loom to generate a digital takeup command signal, a driver circuit for generating a drive signal in response to the takeup command signal and applying the drive signal to a servomotor for driving a winding roll to wind a woven fabric, and a digital feedback circuit for feeding an amount of rotation of the servomotor back to the arithmetic control unit.
