Definitions

  • the invention relates to a method for producing a Thread in an integrated spin-twist process after Double-wire principle with the features from the generic term of claim 1 and a device for performing of the method with the features according to the preamble of claim 5.
  • the rotating component which contains the thread guide element, by means of which the thread is guided in the thread balloon, as pot firmly connected to the spindle rotor, at the top two in the axial direction to each other opposed annular components are arranged, that limit the annulus between them.
  • the two ring-shaped Parts are through spoke-like connecting elements, that penetrate the annulus, connected to each other, the thread guide element in one of the connecting elements is arranged.
  • the invention has for its object a method and a device with the features from the preamble of Claim 1 or 5 so that the feed minimal fiber disorientation of the fiber material occurs and the noise is significantly reduced.
  • the basic idea of the invention is the thread balloon free thread, that is, without guidance through a closed Guide the thread guide through the annulus.
  • the dissolved fiber flow is still transverse to the annulus fed.
  • the Thread balloon or the thread forming the thread balloon the fiber stream completely unprotected.
  • the invention opens up yet another possibility that Fiber disorientation when feeding the fiber material belittling.
  • the Pressurized annulus To feed the fiber material, the Pressurized annulus.
  • the vacuum flow can now on the one hand into the fiber material feed channels from the annular space be introduced and on the other hand by the one on the thread exit side of the annular space Annular gap in a closed space between the top of the inner housing and the one with the centering opening Cover of the outer housing. This creates an air flow from this room through the annular gap into the annular space that tends to disorient fibers that are in have penetrated this space or into the annular gap into the Promote annulus back, making it highly likely a reorientation of these disoriented fibers occurs.
  • the vacuum flow is in contrast to the known method from the annulus only through the fiber inflow channel, but through the Annular gap and also through the opening at the centering point of the Thread balloons. A desired dosage of the vacuum flow can then be done easily from this point, e.g. by throttling be made.
  • Figure 1 shows a double-wire spinning twist spindle.
  • a hollow shaft 23 can be rotated by means of a bearing block 22 stored, the outer, in the representation lower end a suction air source, not shown, can be connected.
  • a motor 9 carries a radial one outward spindle rotor disk 26 with a substantially Radially guided thread guide channel 27.
  • a twister 7 is attached, in the wall of which a thread guide tube 3 is guided upwards connects with its lower end to the thread guide channel 27 and from its upper end the thread F3 through one further Annulus 10 explained in more detail below to the centering point 37 exits.
  • spin pot 12 On the upper end of the hollow shaft 23 is interposed of suitable bearings an essentially closed, against rotation via permanent magnet pairs, not shown secured spin pot 12 stored in the essentially has the shape of a cylinder with a Floor 12.1, an outer wall 12.2 and a removable cover 12.3. Within this spinning pot 12 are two rotor spinning devices R1 and R2 housed their spinning rotors 1 and 2 are motor-driven. Through the lid 12.3 are fiber material feed pipes opening into the spinning rotors 1 and 2 led, one of which is a feed pipe 6 is visible in Figure 1.
  • Thread take-off pipes 31 and 32 through which the in the Spinning rotors 1 and 2 produced filaments F1, F2 are drawn off before they are guided by piecing wheels 8.1 and 8.2 through the upper inlet end 11a of the downward Run in spindle axis 11.
  • the spin pot 12 and the twister 7 are of an outer housing Surrounded 34, which carries a removable cover 35. On the top of the lid 35 of the outer housing 34 is located located as a centering point coaxial to the spindle hollow axis a thread outlet opening 37, to which a not shown Draw-off mechanism for the F3 thread connects.
  • the lid 12.3 of the spinning pot 12 has on its top a cover 12.4 on the interior of the spin pot 12th opposite the space between the top of the spin pot 12 and seals the lid 35 of the outer housing 34. Without these Cover 12.4 would create a bypass to that above the annulus 10 and the annular gap 15 guided vacuum flow.
  • the annular space 10 is on the one hand from the inside of the outer case 34 and the outside of the inner housing 12 is limited and is at its lower Thread entry side through the upper end of the twisting pot 7 completed, the upper end between sealing rings 14.1 and 14.2 runs that the annulus against under higher Seal pressurized rooms.
  • On its upper thread exit side is the annular space 10 via an annular gap 15 connected to the space below the cover 35.
  • the fiber material the annular space 10 of not shown, in itself known resolution units from the fiber material feed channels 4.1 and 4.2 fed. It then passes over the fiber material feed channels 6 by means of the generated Vacuum to the spinning rotors 1 and 2.
  • the generated there Threads F1 and F2 run over the piecing wheels 8.1 and 8.2 and are then the spindle hollow axis 11 for embossing the fed the first twist of the thread.
  • the twisted threads are already twisted through the thread guide channel 27 and the thread guide tube 3.
  • the thread F3 then passes through at the upper end of the thread guide tube 3 Exit opening 3.1 in and into the annular space 10 by the fiber stream immediately in the course of the spindle rotation, that is, unprotected through a thread guide element. It leaves the annular space 10 through the annular gap 15 and runs to centering point 37 from where it is subtracted and to one Cross-wound bobbin is wound up.
