Definitions

  • This invention relates to a device for equalizing the thread tensions for twisting devices, in which during each spindle rotation several twists are imparted to the thread.
  • the novelty consists in that, for accommodating a thread reserve between the thread delivery point in the hollow spindle and the twisting disc, a thread storing ring is arranged, rigidly connected to the whirl or to the twisting disc.
  • the hollow spindle guiding the thread to the thread storing ring can be cast in the flyer,
  • the thread storing ring is either constructed as a divided ring or composed of separate thread guide rollers. It may however be a closed ring having a groove in its circumference for accommodating the thread reserve.
  • the excess thread is wound on the storing ring so that the reduced friction is increased, owing to the thread passing over a greater or lesser portion of the circumference of the storing ring, and consequently the equalizing is again established relative to the centrifugal force of the balloon.
  • the stored thread reserve unwinds, the friction occurring on the storing ring being thus reduced so that an equalization of forces again occurs between the friction and the centrifugal force of the balloon.
  • the winding of the thread around the storing ring is effected in that the balloon increasing in size la s behind the revolving speed of the spind e.
  • Fig. 1 shows t e twisting device in long1- tudinal section.
  • Fig. 2 is a section on line lL-lll of Fig. 1.
  • Fig. 3 is a similar section as Fig. 2 but of a modified form of construction.
  • Fig. 4 shows in lon itudinal section a second modified form construction of a twisting device.
  • Fig. 5 is a section on line V-V of Fig. i.
  • the rotary twisting spindle 1 is constructed as a hollow spindle and carries on its front end a loosely slipped on spool holder 2 for the bobbing 3 from which the thread is running 0d.
  • the spool holder 2 and consequently the thread running of? bobbin 3 are held in position of rest relative to the rotating spindle by a. weight 4.
  • a twisting disc 5 is rigidly connected to the twisting spindle 1, whereas the spindle means of a whirl 6.
  • a thread storing ring 7 is provided, which is constructed either as a divided ring or composed of separate thread guide rollers (Figs. 2 and 3).
  • the thread 10 coming from the running oil bobbin 3 is guided to the running on bobbin through the hollow twisting spindle 1 over the thread storing ring 7 and twisting disc 5.
  • the thread tension decreases owing to irregular thread thickness or, in the case of lateral pulling oif, owing to the different thread running 0d angles and owing. to the changing diameter of the bobbin from which the thread is running ofl or for any other reason, the excessive quantity of thread is wound around the circumference of the thread storing ring 7, as the thread 5 lags behind relative to the spindle spe d, as
  • the boon becomes larger, owing to the air resistance. Consequently the forces are equalized in that the reduced fiiction of the thread on the thread storing ring, a the dropping of the thread tension, is a in increased until it is M; to the can 13!. force of the thread baloon. If, however, or any reason, the tension of the thread increases, the thread reserve wound on the thread storing g is fed to the thread haloon owing to the tangential thread pull on the twisting disc so that also in this ce an equalization of forces relative to the centrifugal force of the thread balloon tes place owing to the reduction of the friction.
  • Fig. 5 of the drawings the running ofi of the thread is shown in several positions from the delivery point of the hollow spindle over the storing ring up to the edge of the twisting disc.
  • the thread is wound several times around the storing ring, whereas the thread along the dash line runs ofi directly from the twisting spindle over the twisting disc.
  • the full line shows only a short, winding of the thread on the thread storing ring.
  • the thread consequently surrounds a greater or lesser portion of the circumference of the storing ring according to the variations in friction and passes from this ring in tangential direction over the twisting disc to the winding bobbin.
  • the groove 8 in the thread storing ring 7 presents the further advantage that in case the thread is wound several times around the thread storing ring, the lower thread layers cannot be thrown in outward direction owing to the centrifugal forces, so that in all cases entangling of the stored thread with the running oil thread is avoided.
