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.

False twist machine

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).

False twisting apparatus

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.
