ABSTRACT:
An electropneumatic system to control yarn tension in a yarn winding apparatus in which an electrical resistance strain transducer is associated with the yarn line being wound for generating a signal indicative of tension. This signal regulates a motor driven valve which controls pneumatic pressure used to regulate the winding apparatus. A heat responsive negative feedback control is coupled into the system shunting the electrical resistance strain gauge to provide an anticipating signal to minimize overshoot in the control system.
