Definitions

  • the invention relates to a method of producing a yarn, wherein a Delivered by a drafting roving is first subjected to a compacting and then rotated by means of a ring-spinning device, and wound up as well as a spinning machine, by means of which such a method can be performed.
  • Compression devices in the form of provided with a perforation, rotating cylindrical rollers (DE 44 26 249 A1) or provided with a perforation, circulating, flexible straps (EP 0 635 590 A2) are known.
  • the method according to the invention accordingly starts from drawn, unconsolidated fiber slivers, compacts these fiber slits and rotates these compacted fiber slits thread-balloonless or yarn balloon-reduced by means of spindle attachments on spin spindles of ring spinning devices before they are wound up by means of these ring spinning devices.
  • the core thread In a core yarn, the core thread should be embedded as completely as possible into the outer fibers defining the outer appearance. In normal core yarn spinning, this is done by supplying the core thread to the roving that has spread widely in the last, generally the main drafting zone, while laying the sheath fibers around the core thread by rotating the fiber structure between the pair of delivery rollers and the rotation-imparting member , so usually a ring spinning spindle. This embedding is often incomplete at some points along the yarn, which is a loss of quality of the produced Coregarnes.
  • each roving tapers a core thread or run several core filaments and it is formed by rotation of a Coregarn rotation.
  • the core thread can also be fed directly to the compression zone.
  • the core thread may be fed to the drafting device from the side, from above or from below, on which the belt is arranged and routed around the deflection edge at the inlet side of the belt.
  • the strapping in the region of its inlet side is assigned a guide roller, around which the core thread is guided.
  • the core thread may also be supplied to the periphery of this suction roll.
  • the spinning machine has a drafting 1 common design with an input roller pair 2, a middle roller pair 3 and a pair of output rollers 4.
  • the bottom rollers 2 ', 3' and 4 'of the roller pairs are formed as steel rollers, which extend over the length of the drafting zone of the spinning machine and have ribbing on the area of work stations.
  • This drafting system 1 delivers a fully stretched, but not yet solidified by rotation roving 8 from. It is understood that the invention can also be implemented in conjunction with drafting systems of other types.
  • This drafting 1 different compression devices 10 may be arranged downstream of the supplied from the drafting roving 8.
  • the lower roller 14th be wrapped by a transport belt 16, which extends by means of known guide means such as. A deflecting rail close to the nip line of the pair of output rollers 4 of the drafting system 1.
  • the transport belt 16 By the transport belt 16, the sliver 8 is supported and supported and prevented from tearing.
  • Fig. 4 shows an embodiment in which the suction roll 26, which may be similar to the suction roll 11 described in connection with Fig. 1, arranged under the run of the roving 8 and designed as a driven lower roll. It is associated with it at least one top roller 27, which serves as a rotation stop for the issuing by the rotation device - here in the form of a ring spinning device - initiated rotation. At the beginning of the compression zone 25, a further top roller 28 may be arranged.
  • the upper rollers 27, 28 are preferably formed as twin rollers and supported and loaded with the upper rollers 2 ", 3" and 4 "of the drafting system 1 in its support and loading arm 6.
  • the suction roller 26 contains the suction chamber 20 separated by a shield 19, which supports the compaction zone 25 delimits.
  • a suction belt 31 which may correspond to the above-described suction belt 29 of FIG. 5, wraps around a lower roller 32.
  • This lower roller 32 rests on a driven, further lower roller 33 which extends through the stretch field region of the spinning machine.
  • the looped by Saugriemchen 31 lower roller 32 is associated with a top roller 34.
  • the looped by Saugriemchen 31 lower roller 32 and its associated upper roller 34 are formed as twin rollers and held in a support and loading arm 6 and pressure loaded.
  • the pressure-top roller 34 may have elastic coating 5 or - since it rests on the Saugriemchen 31 made of elastic plastic - also have a steel jacket.
  • the compacting device 10 can also have a suction rotor 35 containing the perforation 12 on its peripheral surface.
  • the suction rotor 35 is arranged so that the plane of its perforation 12 lies approximately in a plane tangent to the rollers 4 ', 4 "of the pair of delivery rollers 4. In Fig. 8, the suction rotor 35 is cut in the plane of its perforation 12.
  • the inside of the suction rotor 35 again contains a suction chamber 20 connected to the suction source 24, the suction line 21 runs through the hollow axis of the suction rotor, and at the periphery of the suction rotor 35 a pressure roller 36 is resiliently pressed by means of a tension spring 37 at the end of the compression zone 25.
  • the suction rotor 35 may be driven by means of a voltage applied to its hollow shaft tangential 38.
  • the lower rollers 2 ', 3' and 4 'of the drafting system 1 and the driven lower rollers 14,15; 26, 30 'and 33 of the respective compression devices 11 are driven by a in Fig. 1 by dash-dotted lines of action 39 symbolized transmission in coordinated speed ratios.
  • 5 6 and 9 and 10 15, 30 'and 31 have the lower rollers, one of which runs from the roving 8 in the area in which its rotation is given a diameter, as he has generally found in drafting systems for the processing of the respective staple fibers as appropriate. This diameter is, for example, in cotton 27 mm to 32 mm.
  • the drafting unit 1 from the pair of output rollers 4 delivers a roving 8, which has a certain width due to the diameter of the incoming roving and the drafting work.
  • This roving 8 is supported in the embodiments of FIG. 1 by the transport belt 16 to the suction unit 11, 26, 29, 31 and 35, respectively.
  • the roving 8 is subject to the induced draft through the perforation 12 of these suction units. Due to the induced draft, the fibers lying laterally in the roving 8 are sucked to the narrow line of the perforation 12 and the roving is thereby compacted. In this compressed state, it is delivered to the ring spinning device 40 and solidified and twisted by it by rotation.
  • the spindle attachment spinning fingers 46 and spinning crown 47 in cooperation with the yarn guide 48, the running of the compacting device 10 thread 49, it wraps around the sleeve 50 and directs him without thread balloon or with only a very small, reduced thread balloon the ring rotor 45.
  • FIG. 4 illustrates the possibility of feeding the core thread 53 directly to the compression zone 25. Here, it is fed to the inlet side of a roller pair formed by the suction roller 26 and the upper roller 28 assigned to it.
  • the view of a coregear device 51 of FIG. 9 relates to the embodiment of the compression device according to FIG. 2.
  • roving 8 is therefore not or only slightly varied. So that the core thread 53 of the rove B always tapers in the middle, a core thread guide 55 must be provided which on the one hand neutralizes the traversing movement of the core thread in the course of the core thread bobbin 54 and, on the other hand, the core thread to the fiber ditch 8, i. centered to roving inlet funnel 56 of the drafting 1. This position must be adjusted and maintained at a traversing the roving B. This can be done in that roving inlet funnel 56 and core thread yarn guide 55 are mechanically coupled, which is indicated in Fig.
  • Kemfaden 53 accordingly runs into the at the beginning of the compression zone 25 still wide-running roving 8 and is there dense and opaque encased by the under the action of the induced suction belt close together sheath fibers of the roving and the core yarn 58th
