Abstract
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.
