Abstract

Preferably the grooves are helicoidal. The high-speed spindle may be magnetic, for texturising yarn. The grooves eliminate the effects of spinning finish, which reduces the friction coefft. of the surface after prolonged processing. The disc may have a non-magnetic support, e.g. Al, and its friction surface is elastic, e.g. polyurethane.
