Open the CIPO recordAbstract From the Canadian patent
When a skein of yarn is drawn through a protective tube prefabricated in the form of a woven, tubular textile fabric of the type of a rope drive 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 longitudinally during the manufacturing process. In this pushed-together form, they surround the upper reach and the lower reach of the rope drive formed during drawing in of the skein of yarn by the strands of yarn being placed around the wheel discs of the manufacturing apparatus.
