ABSTRACT:
A direct current electromagnetic disc type tension control which has alternating current superimposed on the direct current circuit to allow the electromagnet to vibrate the tension discs in order to break the contact between the tension discs to lower the resistance to rotation of the discs by the yarn passing therethrough. The direct current circuit includes a source of high voltage and a source of low voltage and the current from the low direct current voltage source is cut off periodically and momentarily.
