  • Patent number: 4365468
    Abstract: The false twist machine has a texturing part arranged below heat treatment zones in which three supply devices and a false twist device are superimposed and staggered from the back to the front in such a manner that in threading in of the thread into these devices turning about and overhead working processes of the operator are avoided. The thread paths formed by the threading in are placed one in front of the other in the sequence of the threading in process. A bobbin creel is movable to the texturing part and is equipped with a thread transfer device which transfers the threads coming from the individual creel bobbins into the vicinity of the first supply device. The winding device is arranged opposite the texturing part at a distance forming an operating alley and gives off the full bobbins to the outerside of the winding device opposite the operating alley. The empty bobbins can be moved from the machine end into a readiness reserve position.

  • Patent number: 4237686
    Abstract: The present invention concerns a false twist apparatus (1) with friction discs (3) arranged at mutual distances on a shaft (2) and with thread guides (4) extending to between the discs (3), for imparting twist to a thread (11) guided friction-contactingly over the friction discs by the thread guides. The thread guides in this arrangement are provided with a concave curvature, as seen with respect to the direction of movement of the twist imparting surface (F).

  • Patent number: 4194350
    Abstract: The thread deflecting element is provided with an arcuate groove through which the thread passes as well as with compressed air ducts which deliver compressed air at the entrance of the groove on the side within the groove curvature and at a point downstream of the groove apex on the side outside the groove curvature. The air is delivered via ducts within the plate forming the deflecting element. The travelling thread is relieved of a degree of tension in the deflecting element so as to equalize the tension in the two lengths of the thread loop passing over the two heating paths of the heater.

  • Patent number: 3998041
    Abstract: A method of, and apparatus for, fabricating a textured yarn or the like comprising a false twist device containing a number of friction disks arranged in spaced coaxial relationship with respect to one another in succession and thread guide elements helically distributed along the circumference of the false twist device. The thread guide elements extend into the space between the disks and are helically arranged along the circumference of the false twist device in such a manner that a yarn contacting the disks and guided by the thread guide elements contacts the false twist device along a helix, the helix angle or pitch of which decreases in the direction of travel of the yarn.
