Definitions

  • the invention is concerned with a spinning process, which by means of a drafting system and a swirl device downstream of the drafting device can be implemented, and with an appropriate spinning device. Above all, comes as a twister Ring traveler system in question, the invention not based on the use of such The system is limited because alternatives (e.g. pneumatic swirlers that work with Drafting systems work together) are known.
  • the invention is based on the knowledge that the latter assumption is a fleece angle is also necessary after bundling the fiber structure, is wrong, and that the omission of the fleece angle can lead to various advantages.
  • the invention accordingly sees a spinning machine with a drafting system, a Swirl generator and a condenser between the drafting system and the Swirlers before.
  • the condensing device is, however, in relation to the swirler arranged that the fibers leaving the condenser or the condensed Fiber structure essentially without further deflection on the condensing device or at the exit roller of the drafting system into the twisting fiber sliver can be passed on.
  • a Swirl stop e.g. are in the form of a pressure roller, which act back of the swirler in the condenser.
  • the swirler is preferred formed as a ring runner system.
  • the arrangement can be made such that the condensed fiber structure in the essentially passed on to the ring traveler system without any further redirection is ("spinning without thread guide” - see DE-A-195 14 409).
  • an outlet roller of the drafting system is also used as an element of the condensing device serves (e.g. according to CH-C-681 372), can be done by omitting the fleece angle the exit roller a reduction in the roller diameter can be achieved, resulting in lead to an improvement in the geometry of the main draft zone in the drafting system can.
  • the condensing device can, for example, be equipped with an apron guide DE-C-4323472 can be realized.
  • the drafting system axes are (in contrast to the drafting system according to DE-A-4130025) arranged parallel to the longitudinal extent of the machine.
  • drafting device 1 essentially consists of a drafting device 1 for a Fiber sliver 2 and a ring spinning device 3, which a ring bank 4 with a ring 5, a runner 6 mounted on the ring 5 and one not visible in the figure has a spindle whorl 7 drivable spindle.
  • the spindle carries in conventional Way a sleeve 8A, whereupon the yarn produced in the spinning station to a bobbin 8th is wound up.
  • the exit rollers of the drafting system 1 are indicated by the reference numerals 9, 10, wherein the lower exit roller 10 has a deflection path 11 for the drawn fiber sliver forms.
  • a pressure roller 13 is at a distance in front of the outlet end 12 the deflection path 11 is provided, the pressure roller 13 together with the roller 10 forms a guide gap 14 for the fiber sliver 2.
  • the exit roller 10 forms thus a transverse to the match axis effective sliding surface G, which over the Runner 6 of the fiber sliver 2 has been screwed into the area of the guide gap 14 should extend so that due to the in the outlet-side area of the sliding surface G effective yarn twist the protruding fiber ends across the fiber sliver around it be wound.
  • the exit roller 10 with a Provide suction zone 16 for the stretched fiber structure 2.
  • the outlet roller 10 has a corresponding suction insert 17.
  • On both Longitudinal sides of this suction zone 16 are each provided with a slot nozzle 18, which has a blown air flow generated with a flow component directed transversely to the suction zone 16.
  • This flow component causes such a fiber bundling that the There is no need for the fibers of a wide bandage to be twisted in Connection to the guide gap 14 in a triangular area on the round Need to merge yarn cross section.
  • FIGS. 2 to 4 show the same elements with one exception - the blowing air nozzle 1 is in the arrangements according to FIGS. 2 to 4 by a cover 20 according to DE-A-44 26 249 has been replaced. Since the present invention with the lid 20th has nothing to do in and of itself, a detailed description is omitted here, the content of DE-A-44 26 249 hereby incorporated into the present disclosure should be. However, the modifications to be described can also be carried out in one device are used, which has a nozzle according to FIG. 1.
  • the suction zone 16 is not necessarily at the clamping line needs to end at the end of the guide gap 14.
  • the suction zone 16 can either even before the clamping line, i.e. the line of contact between the rollers 10 and 13, or only end afterwards.
  • FIG. 3 differs from that of FIG. 1 in that the rollers 9 and 13 are displaced relative to the roller 10 in the material flow direction have been so that the size of the suction zone 16 in Fig. 3 of that of 1 corresponds to the arrangement. This enables the inclination of the Drafting device 1 compared to that in FIG. 1.
  • the suction zone 16 is also the same size as that 1, in FIG. 4 the position of the roller 9 relative to the roller 10 in comparison 1 remains unchanged. In this case, however, is the diameter of the roller 10 reduced, which is an improvement in the transfer of fibers from the guide straps in the main draft zone of the drafting system 1 to the outlet rollers 9, 10, as explained below with reference to FIG. 5.
  • the drafting system 1 comprises a pair of infeed rollers 21,22 and a pair of rollers 23,24, the fiber guide straps 25,26. It is also indicated a "drafting plane" E, which the clamping line of the pair of rollers 21, 22, the nip line of the exit roller pair 9, 10 and the entrance nip line the straps go through 25,26.
  • the straps 25, 26 are deflected by a guide element (not shown), to form a "nose” near the nip line of the exit rollers 9, 10.
  • the Fibers are therefore guided in the main draft zone between the straps 25, 26 to they reach the exit in the "nose".
  • Suitable guide elements are known and are therefore not explained in more detail here, preferably a curved one Form the guide path for the fiber structure, as indicated schematically in FIG. 5 and e.g. is explained in DE-A-43 44 319.
  • the diameter of the lateral surface 10A of a suction drum that can be used today is approx. 60 mm.
  • An arrangement according to the invention is preferably used Diameter of 55 mm or less is possible because of a greater curvature the fiber assembly on the exit roller whose control is improved.
  • the figures 6 and 7 show further possible improvements.
  • the rotating fuse or the yarn 2 on the Side of the exit roller 10 measured with the normal N through the centers of the rollers 13 and 10 or through the common clamping line an angle F greater or include 90 ° so that the yarn 2 detaches after passing through the nip 14 can be screwed in by the condensing device after it 6 by the pressure roller 13 has been deflected by the angle E.
  • FIG. 6 again shows the lateral surface 10A, the pressure roller 13 according to FIG. 4 and the rotating fiber sliver 2.
  • the pressure roller 13 still further down into position 13A, the position of the Swirl generator (not shown) remains unchanged. This results in a fleece angle A on the axis of rotation of the pressure roller 13A, or a sliding surface G (or a "Umpressivesbogen") on its circumference.
  • the yarn or the fiber sliver 2 according to FIG. 6 has a fleece angle on the pressure roller 13 covered and this is preferably covered with a rubber jacket remains the once achieved compaction of the fiber sliver 2 when running over the fleece angle E due to the friction between the rubber jacket and the fibers received so that there is a comparatively narrow for the screwing Spinning triangle results.
  • FIG. 7 again shows the drafting elements which have already been used in connection with FIG. 5 have been described.
  • the plane E1 which the clamping line of the rollers 21,22 with the Entrance clamp line connecting the straps but no longer runs through the clamp line of the rollers 9, 10 through.
  • the latter clamping line is lowered compared to level E1, which is a further approximation of the nose of the straps 25, 26 to the clamping lines the exit rollers.
