Abstract
A yarn brake is arranged in the direction of the traveling yarn after the section where the yarn tension has to be kept constant, and the yarn tension is measured before this brake. The yarn is fed to and drawn off from the brake at a substantially constant speed. The control, contrary to the hitherto known processes, has to be carried out inversely, that is, for example, when the measuring feeler signals a rise in the yarn tension in the section to be controlled, the braking effect of the brake has to be increased until the set value of yarn tension in this particular section is attained again. Correspondingly, the braking effect has to be decreased when the yarn tension measured is too low.
