ABSTRACT:
There is described a two-for-one twisting spindle having a supply receptacle for a lubricant arranged in a base of a protective pot, a region of an outer circumferential surface, of the protective pot, over which the revolving thread passes when the spindle is operating, communicating with the supply receptacle in such a way that lubricant is brought to the said region of the circumferential surface. Thereby the supply receptacle is in a stationary part of the spindle, so that lubricant content in the receptacle has no inertial effect on the running of the spindle. The arrangement enables consistent but not excessive wetting to be provided for the thread without the thread being subjected to undesirable stresses while the spindle is operating. In the arrangement shown, a protective pot 4 has a sidewall 5, over which thread 16 passes when the spindle is operating, and a base 7 having a cavity holding a supply of lubricant 10. Projecting into this cavity is an annulus 11 of absorbent material or material having a capillary structure, this annulus 11 extending through a circumferential slotted opening 15, whereby the thread fed past the outside edge of the annulus is wetted.
