Abstract (en)

[origin: EP1091032A2] A let-off control device for a weaving machine comprises a basic speed calculator (11), an average tension calculator (18), controller (14) and a control amplifier (17) to drive a let-off motor (M). The controller (14) operates in synchronism with an operating cycle determined by a clock signal (Sc), independently of operating cycle of the average tension calculator (18), with no likelihood that substantial control parameters will fluctuate due to variations in the operation speed of the weaving machine. <IMAGE>
