Definitions

  • the invention relates to a double-wire twisting spindle, containing a rotationally driven spindle and one on the spindle, secured against rotation Protective pot that either holds at least one Supply spool is formed or at least two open-end spinning turbines to generate in the hollow spindle axis insertable thread.
  • the thread With double-wire twisting spindles, the thread becomes common pulled up from the coil, which then the hollow Spindle axis down to the rotating thread storage disc goes through; the thread then passes through the thread storage disc radially outward, wraps around it in a certain area, then forming a thread balloon between the protective cup secured against rotation and the balloon limiter, which is also stationary, upwards led to the thread guide eyelet determining the balloon tip from where the thread then becomes a take-up unit runs.
  • the thread storage disc has the Purpose, between the exit point of the thread from the Take up a thread reserve from the spindle and the thread balloon, which is a balance between the inner and outer thread tension creates.
  • This group includes double-wire twisting spindles, bei which the balloon limiter is rigidly connected to the spindle is and thus inevitably rotates at the spindle speed (see DE 1 840 338 U1; NL 68 583; DE 29 52 283 A1).
  • the double-wire twisted spindle treated in DE 1 268 031 C1 can be counted in the case of a thread storage jacket designated balloon limiter jacket, which together with the spindle rotates, only over part of the spindle height extends to which is stationary in the axial direction Balloon limiting ring connects.
  • this embodiment leads the stationary balloon limiting ring braking of the thread balloon section lying against it, so that it leads to thread storage is coming.
  • Double-wire twisting spindles according to US Pat. No. 2,127,921, 2 609 652 and 3 007 299 as well as GB 1 245 010 Group of double wire twisting spindles is the one from the rotating spindle core radially emerging thread for reduction the thread tension through a coupling coupled to the spindle co-rotating thread channel guided.
  • Thread storage is omitted due to the lack of a storage facility as well as largely free balloon expansion.
  • the invention has for its object a double wire twisting spindle to create, where those acting on the thread Forces are reduced to drive the spindle required drive power kept as low as possible and productivity is also increased.
  • a double-wire twisting spindle is used to solve this task with the features of the claim.
  • Figures 1 and 2 are for constructive or functional same or comparable elements have the same names and reference numerals are used.
  • the double wire twisting spindle shown in Figure 1 contains one for example in a not shown Spindle bench with stationary, cylindrical outer housing 1 with bottom 1.1 and bearing bracket hub 1.2.
  • a e.g. formed as a hollow spindle 3 spindle which means a single motor drive 4 not belonging to the invention is rotationally drivable.
  • a bearing 5 is on the upper end of the spindle 3 a protective pot 6 is mounted which has a protective pot jacket 6.2, a protective pot base 6.1 and a protective pot hub 6.3 to which the spindle hollow axis 6.5 and, as shown, connect a thread inlet pipe 6.4.
  • the spindle hollow axis 6.5 is a and shown only schematically Liftable thread brake 17 not belonging to the invention assigned according to DE 29 14 656 C2.
  • the protective pot 6 takes at least two adjacent Spinning units, preferably in the form of OE spinning turbines 70, 70 on which dissolved fiber material through Feed channels 71 is supplied.
  • the one from the spinning turbines The spun threads produced are passed through rollers 72, 72 the thread inlet tube 6.4 is drawn into the spindle hollow axis 6.5, to each other according to the double wire twisting process to be twisted.
  • the rotational drive in the not belonging to the invention in the protective pot 6 stored Open-end spinning turbines 70, 70 are made using electric motors 73, 73.
  • Thread channel 7.1 On the spindle 3 is a rotating with the spindle Turntable 7, the one with the axial holes the protective cup hub 6.3 and for the first thread spindle type 1 also adjoining the axial bore of the spindle 3, essentially radially extending thread channel 7.1 is provided.
  • a cylinder jacket 9 put on, as shown, about its entire height, or even part of it Height, with a thread guide, in particular thread guide channel 9.1, is provided, the lower end of which Thread channel 7.1 connects.
  • An intermediate housing 11 forming an energy-saving pot 11 with its hub 11.1 with the interposition of a bearing 10 mounted freely rotatable on the outside of the bearing bracket hub 1.2.
  • a thread a drawn off from the supply spool A runs axially through the thread inlet tube 6.4, the spindle hollow axis and the axial bore 6.5 of the protective pot hub 6.3, before passing through the particularly radially running thread channel 7.1 into the thread guide member or the thread guide channel 9.1 with the spindle rotating cylinder jacket 9 is inserted and passed through.
  • the thread emerging at the upper end of the cylinder jacket 9 is then, as shown in FIG. 1, optionally, with balloon formation, in a conventional manner to the thread guide eyelet 12 located in the extension of the spindle axis and finally fed in a conventional manner to a winding unit (not shown).
  • the thread leaving the thread guide channel 9.1 can also 2 on the route to the thread guide eyelet 12 ' be guided by a hood 18 on the outer housing 1 or the like is put on.
  • Transition between the hollow spindle axis and the radial extending thread channel 7.1 is not part of the invention and only schematically illustrated injector arrangement 20 intended.
  • This injector arrangement is used to thread the thread 20 compressed air supplied through the hollow spindle 3, whereby a to the upper end of the thread inlet pipe 6.4 held thread sucked in by suction and through the radial thread channel 7.1 and the subsequent thread guide channel 9.1 is blown through.
