  • Patent number: 4201036
    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: 4129979
    Abstract: A yarn-twisting apparatus comprises a spindle receiving the supply spool or bobbin, a rotating can or sleeve surrounding the spool and the bobbin, a yarn takeup arrangement for drawing the yarn from the upper end of the can, and a housing surrounding the can. According to the invention, the stationary housing and the upper and lower ends of the spindle are provided with closures which reach close to the spindle at the bottom and form an opening traversed by the yarn at the top. Means is provided for enabling the upper closure to be removed or displaced for ready access to the interior of the housing. The system reduces the power consumption required for twisting the yarn.
