Abstract
A method of processing an endless synthetic yarn is disclosed, wherein the yarn is withdrawn from a spinneret, and advanced into contact with a feed system which is operated under conditions which produce slippage between the feed system and the advancing yarn. As a result, a constant frictional force is exerted on the yarn irrespective of fluctuations of other parameters, and a precisely defined reduction of the yarn tension is achieved which facilitates the subsequent winding of the yarn into a package.
