Abstract
A yarn false twisting apparatus is provided which includes a pair of twist imparting circular discs, with one of the discs being thin and flexible. A pressure applying member is positioned to upset the flexible disc toward the other disc at the twisting zone. In order to avoid undesired deformations of the flexible disc, the flexible disc includes reinforcing means, such as embedded reinforcing fibers, a reinforcing sheet, a discrete annular ring embedded in the material of the disc, or combinations thereof.
