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 and between the tension discs and the electromagnet to lower the resistance to rotation of the discs by the yarn passing therethrough. The direct current electromagnetic tension control is an electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.
