Abstract
The knitting machine has knitting elements including needles, sinkers, and the like and guide parts for the knitting elements, including cam parts, guide tricks and the like, these groups of parts moving relative to each other and being provided with mutually contacting sliding surfaces or faces. To reduce heating during operation, the need for auxiliary lubricating devices, and to lower power requirements during operation the opposing sliding surface or faces of the moving parts of the knitting machine are at least partially provided with a friction-reducing and wear-resistant coating of diamond-like carbon. This coating is applied by a plasma CVD process (FIG. 3).
