Abstract
A yarn false twisting apparatus is disclosed which comprises a pair of circular discs which are mounted for rotation about generally parallel spaced apart axes, and such that portions of the surfaces are disposed in opposing face to face relation and define a twisting zone therebetween. One disc is mounted to its supporting shaft by means of an elastomeric body member, which permits the disc to resiliently incline with respect to the axis of the shaft. A pressure applying member acts upon the back side of such disc to resiliently bias the same toward the other disc at the twisting zone.
Claims4
A yarn false twisting apparatus comprising
- a pair of twist imparting members, with each member including a yarn engaging friction surface, and at least one of said members comprising a circular disc,
- means rotatably mounting said twist imparting members such that portions of the respective yarn engaging friction surfaces are disposed in opposing, face to face relationship and define a twisting zone therebetween, said mounting means for said circular disc including a supporting shaft and an elastomeric body member interposed between said circular disc and said shaft so as to permit said disc to resiliently incline with respect to the axis of said shaft,
- drive means for operatively rotating each of said twist imparting members about their respective axes, and
- means for resiliently biasing said circular disc toward the other member only at said twisting zone,
- whereby a yarn may be continuously moved through said twisting zone while having twist imparted thereto by frictional contact between the yarn and the respective opposed friction surfaces.
