Abstract
A skein of yarn is drawn through a protective tube prefabricated of a woven, tubular textile fabric and is connected in order to form an endless sling. The protective tube is formed of two length sections. These length sections, which are of approximately the same length, are pushed together only slightly during the manufacturing process. In this pushed-together form, they surround the upper reach and the lower reach of the drive formed during drawing in of the skein of yarn by the strands of yarn which are placed around the wheel discs of the manufacturing apparatus.
