Definitions

  • the invention relates to a spinning machine for producing coregarn, with an at least one roving pulling drafting system, to which a the roving compacting, circumferential, provided with at least one perforation, under Saugzug standing compression device connects and with a device for Feeds of filament to the roving in front of the compactor.
  • the invention is therefore based on the object, a possibility for a lighter Introducing the coregarn filament on the inlet side of a compacting device to accomplish.
  • the compression zone for the fiber structure a suction zone for the filament in the direction of the compression element is upstream.
  • the filament can, for example, by means of a forward extended compression zone be sucked, wherein the suction area the compression zone for comprises the fiber structure and its upstream suction zone for the filament.
  • the compression device in the feed region for the Filament at least one further, arranged under the perforation suction opening exhibit.
  • the Sieve drum before the compression zone have the suction opening.
  • the additional opening on the top of the suction shoe to the deflection point of the belt or the screen drum up to the nip line between the screen drum and the lower roller is guided at the end of the compression zone, optionally dispensed with an otherwise required centering device for the core yarn filament become.
  • the coregarn filament is then always fed into the perforation and hits always on the in the compression zone sucked to the perforation fiber structure.
  • the fiber structure can be changed. This is a traversing of the fiber structure by sucking the fibers onto the perforation; the position of the Filaments will not be affected.
  • the advantage is that in the drafting area a Traversing is enabled while assigning filament and fiber stranding at the Verdichtungsriemchen is realized and always the same, for example, filament and Fiber bandage in the middle above the perforation. With the conventional drafting system, the Position of the filament, however, when traversing the fiber structure of the position be adapted to the fiber structure.
  • the invention can be advantageously also in the production of so-called Use SIROSPUN yarn.
  • the compression bud which is for the two partial fiber slivers to be compacted have two perforation traces, according to the invention with a third perforation track between the other two Traces equipped, on the top of the suction shoe, the additional intake assigned.
  • the additional intake assigned for compaction equipment with screening drum, the corresponding applies constructive design.
  • For compactors with a screen belt is in addition, another suction slot between and in front of those for the two partial fiber ribbons required.
  • shut-off valve which has a Brake lever of each spindle of the spinning machine is controlled so that it only when stopping a spindle to resolve a yarn breakage is opened.
  • the spinning machine according to the invention has a drafting system 1 with an input roller pair 2, a middle roller pair 4 and a pair of output rollers 6.
  • the Rolls of the middle roller pair 4 are provided with straps 7, which in each case in not shown Riemchenkahanfigen are performed.
  • the output roller pair 6 is followed by a compression device 22, which a Saermiemiemchen 38, which is wrapped around a top roller 39.
  • This Saugriemchen 38 has centrally around its periphery a perforation in the form of in Line arranged suction openings 24.
  • the compression device 22 has a suction shoe 33 with a suction opening 32, which via a suction line 29 with a suction pump 31 and a motor 30 in Connection stands.
  • the upper roller 39 is located with the Saugriemchen 38 on a driven lower roller 40, wherein the area between the roller pairs 39 and 40 and the pair of output rollers 6 forms a compression zone 34.
  • the drafting 1 is associated with a filament delivery 9, the two rolling rollers 10th having.
  • On the Abrollwalzen 10 is a filament coil 11, of which a filament 12 fed via a centering roller 15 of the input side of the suction cup 38 becomes.
  • the suction shoe 33 has on its side facing away from the compression zone 34 as Intake zone 34 'another, lying below the perforation of the Saermiemiemchens 38 Suction opening 50 on.
  • the two openings 50 and 32 are arranged in the suction chamber 28 and can z. B. be separated by a shield from each other.
  • the additional opening 50 provides the advantage of easier insertion of coregarn filament 12 on the inlet side of the lying above the stretching field plane Compression device 22.
  • the present invention is also applicable to a construction in which instead of the suction shoe 33 of FIG. 2, a screen drum 18 is used as a suction roller application.
  • the suction roller 18 is again on its perforation track 23 provided with in-line suction openings 24.
  • the sieve drum 18 rotates about an axis 19 and is by a load not shown pressed on two lower rollers 25 and 26.
  • Within a suction chamber 28 is located a suction opening 32 ', which is covered by a shield 36.
  • a further suction opening 50 ' is provided, which upstream of the compression zone 34, which is present between the two lower rollers 25 and 26.
  • This construction again has, analogously to the embodiment according to FIG. 1 Suction line 29, a suction pump 31 and a motor 30.
  • the core yarn filament 12 is analogous to the embodiment of FIG. 1 via a Centering roller 15 by action of the further suction port 50 'of the compression zone 34th supplied in the aforementioned sense.
  • Fig. 3 there is also the possibility of the invention in a compression device 22 to use to produce false twist.
  • the suction cup 38 two perforation tracks 23 in the form of in-line suction on by means of which two running at the respective workstation of two roving bobbins 67 Faserlunten 68 and 68 'in the drafting 1 over the pairs of rollers 2, 4 and 6 stretched and delivered by the output roller pair 6 next to each other and to fiber slivers 8th and 8 'are compressed separately.
  • a middle perforation track 23 'for a core yarn filament 12 which withdrawn from a filament spool 11 and is fed via a centering roller 15 of the perforation track 23 '.
  • the third perforation track 23 'for the Coregarn filament 12 is on top of the suction shoe 33 'of the corresponding associated with another suction opening.
  • shut-off valve can be used, which is so controllable for example via a special control device, it only when stopping a spindle of the spinning machine is opened.
