Definitions

  • This invention presents a considerable improvement over the known methods, insofar as it permits a regulation of the stretching of the thread, by means of thread guides, to any desired amount, and makes the stretching conditions absolutely uniform at any number of spinning places.
  • Figure I the thread a comes from the spinning bath, is laid over the simple thread guide I), then passes in zigzag form around the thread guides c and d. It then reaches the positively driven drawing roller e around which it is wound once, or several times, and then travels to a takeup spool, or the spinning pot is.
  • the thread guides c and d are fixed to a disk moving on the shaft g. The disk may be turned by the handle h.
  • the rotatory movement of the disk f has not for its purpose only the adjustment of the guides c and d uniformly from place to place, but it also enables one to switch off the brake friction of the thread guides c and d when the spinning is started.
