<p>WARP TENSION CONTROLLER Warp tension controller for a loom, with a comparing means for a measuring quantity which is related to the warp tension and a reference quantity, which through an operational amplifier connected as a PI controller, with in the feedback circuit a resistor parallel to an integrating capacitor, controls an adjusting means for the warp tension, with a switch which during at low speed of the loom, bridges the feedback circuit with a small resistor and switches the integrating capacitor from the output of the operational amplifier to the output of a voltage memory, the input of which is connected to the output of the operational amplifier.</p> |
