ABSTRACT:
A yarn false twisting apparatus is disclosed which comprises a pair of circular discs which are mounted for rotation about spaced apart axes, and such that portions of the surfaces are disposed in opposing face to face relation and define a twisting zone therebetween. In the operative position, one disc is resiliently deflected from its normal plane of rotation at the twisting zone by its engagement with the friction surface of the other disc, or a yarn passing therebetween, to thereby effectively engage and impart twist to the yarn. The bearing housings for the supporting shafts of the discs are held against movement with respect to each other during the twisting operation, and means are provided for automatically separating the housings and thus the discs in the event of a yarn breakage, to thereby avoid wear of the opposing disc surfaces.
