<p>Warp tension controller for a loom, with a comparing means for a measuring quantity 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 voltage memory, the input of which is connected to the output of the operational amplifier, as well as an automatically operated switch which upon switching-off the loom drive, switches the intergrating capacitor from the output of the operational amplifier to the output of the voltage memory.</p> |
