Method of producing an endless sling

A method of producing an endless sling composed of a supporting core made of a skein of yarn, and protective tube made of a woven fabric surrounding the skein of yarn, said protective tube comprising two length sections, and the method comprising the steps of:

• compressing each respective length section;
• pulling a strand of yarn through each of the length sections which have been compressed;
• placing the regions of the strand of yarn which project from the ends of each of the length sections over the circumference of respective wheel discs;
• attaching the free end of the strand with a region of the strand which has not been pulled through the length sections so as to form a continuous strand loop around the wheel discs such that each of the length sections surrounds a different reach of the loop for pulling in the skein of yarn;
• rotating one wheel disc to cause the loop to rotate so that the region of the strand of yarn not yet pulled through the length sections is continuously pulled therethrough thereby allowing a plurality of individual strands to pass through each of the respective length sections;
• removing the length sections and the plurality of strands of yarn passing therethrough from the wheel discs;
• and
• connecting the ends of the length sections together so as to form a continuous protective tube.
