Definitions

  • the invention relates to a method for producing a textile yarn, in which by means of a Opening roller from a sliver to separate fibers to form a fiber structure a circumferential fiber collection surface can be sucked in, which is connected to a suction source Perforation and in which a continuously tightened and removed by turning Yarn is formed from parallel and stretched fibers and a device for Execution of such a method is suitable.
  • the channel is through the Gusset between two interacting, axially parallel, perforated and from a suction train, co-rotating rollers formed between where the yarn is made.
  • moving fiber collecting surface When pulling the fiber package over the stationary. or transverse to the deduction direction moving fiber collecting surface must pull the fibers over the holes of the perforation into which they are partially sucked. There are two versions the risk of fibers being retained in the perforation, thereby losing its parallel and stretched position and becoming undesirable slide on and / or bend like a hairpin and / or corkscrew like that forming yarn.
  • WO 90/08211 discloses a device in which fibers of a sliver, which have been separated by means of an opening roller, to a suction revolving drum can be sucked. In a against the adjacent suction train covered area of the drum, the fiber structure formed by the drum lifted, that is, carried out, temporarily using a false rotating device wrong rotation and finally with a ring spinning device equipped with real rotation and wound up in a cop.
  • the circumferential surface of the drum collecting the fibers which is made permeable to air has a certain width over which the fibers are distributed.
  • the object of the invention was to implement the method practiced with this device to improve and simplify. It solves this task procedurally by that the fibers compress when deposited on the fiber collecting surface be subjected to, which arise when turning the wide sliver de spinning triangle can at least be significantly reduced and on the wrong turning can be dispensed with.
  • the fiber collection surface is provided to be compacted by forming a perforation track under suction has sucked through the fibers to this perforation track and that the wrong rotating device is dispensed with and that of the fiber collecting surface removed fiber structure is immediately subjected to real rotation.
  • the object of the invention is achieved by the Kerim Jones of claim 4 listed features solved.
  • the fiber package formed does not have a Surface to be deducted to which it adheres by suction. Rather, the fiber package is made up of the circumferential surface Deposition area carried out and the risk of adverse Confusion of the parallel fibers is avoided.
  • the circumferential surface can be as endless, flexible straps should be formed that at least a driven deflection roller runs and with the perforation is provided.
  • the rotating Surface designed as a driven, hollow drum roller be that carries the perforation.
  • the driven deflection roller or the drum roller forms a fiber sliver with a counter roller promotional pair of rollers. This achieves the advantage that the withdrawal speed of the fiber sliver is precisely defined and done very evenly and both the constant Cross-section as well as the constant rotation per unit length of the yarn formed is secured.
  • the opening device offers whose also with a correspondingly high delay Fibers could be delivered, the advantages of being a possibility for separating foreign objects and that Inlet roller pair of such a drafting system is bypassed, the extremely slow rotation speed lead to inconsistent running can.
  • the to give the surrounding area a wide perforation and the opening of the suction channel in a first zone in which the fibers are on the fiber collection surface are also carried out wide and rejuvenate them in a subsequent second zone.
  • the opening of the suction channel can be a through opening or also designed as perforated or slit-shaped perforations his. Especially when it is designed as a perforation is, their density in the direction of the circumferential surface increase to preferential suction of the leading ends of the effect sucked fibers and thus a stretched as possible To achieve storage of the fibers in the fiber package.
  • the spinning device according to the invention has a device by means of which fibers are separated from a supplied sliver solved and dissipated.
  • this device can be one of the type used in open-end spinning machines Dissolving device 1.
  • This consists of an in a housing 2 rotating at high speed in the direction of the arrow, with a sawtooth set 3 opening roller 4 and one also driven in the direction of the arrow shown Feed roller 5, the sliver 6 over a feed trough 7 of the sawtooth set 3 of the opening roller 4 feeds.
  • Waste channel 8 from, through the foreign body 9 that when the Sliver 6 are free to be thrown off.
  • the opening roller 4 is the waste channel 8 a fiber channel 10 downstream, through which the fibers 11, due to the high peripheral speed the opening roller 4 individually from the sliver 6 can be solved, occasionally carried away freely.
  • this fiber channel opens 10 over an endless, flexible strap 12, which has two deflection rollers 13 and 14 is guided, of which at least one is driven is and allows the straps to circulate, but also alternatively, the pressure roller 22 can be driven and over direct contact by means of straps 12, the deflection rollers 13 and 14 drives.
  • the strap 12 is centered around its circumference a perforation 15 in the form of arranged in at least one row, small, round holes 16.
  • the perforation can but also a different shape, for example oval or approximately rectangular Holes.
  • the upper strand 17 of the mouth facing the fiber channel 10 Strappy 12 runs over the convexly curved surface 18 lying inside the strappy between the deflection rollers 13, 14 Suction channel 19, which is connected to a pressure sink, not shown is.
  • This surface 18 overrun by the strappy 12 of the suction channel 19 also has a perforation 20 which from a row lying transverse to the direction of movement of the strappy Slits 21 is made.
  • the perforation 20 of the suction channel 19 is designed as elongated slots, even with lateral Offset between the perforations of the suction channel and the strap to ensure the operability of the device.
  • the Length of the area in which the perforations 15 and 20 cover, corresponds approximately to the stack length of the processed Fibers.
  • the one at the outlet of the strap 12 from the perforated surface 18 of the suction channel 19 arranged deflection roller 13 is a pressure roller 22 assigned a pair of rollers 23 with the deflection roller forms.
  • This pair of rollers 23 is a common of ring spinning machines, here shown on a smaller scale ring spindle 24 subordinate.
  • This ring spindle has a driven spindle 25, by means of which a yarn 26 given by a rotor 28 rotating on a ring 27 rotation and wound this yarn into the yarn winding 29 of a cop 30 becomes.
  • those of the resolver 1 isolated fibers 11 by the suction of the pressure sink, the through the perforations 15 and 20 of the straps 12 and the Suction channel 19 in the fiber channel 10 acts on the perforation sucked the strappy.
  • they are stored in a fiber package 31 from that by the circulation of the straps 12 as a fiber fuse 32 carried out of the mouth region of the fiber channel 10 and is fed from the roller pair 23 to the ring spindle 24.
  • the fibers are stored roof tile-like to the endless fiber fuse 32 together.
  • the ring spindle 24 issued by the pair of rollers 23 delivered without rotation Fuse 32 twist and winds the yarn thus formed 26 on the cop 30.
  • the fiber channel 10 opens above the surface of a drawn in the direction of the Arrow rotating, driven drum roller 33 around its Perimeter has a perforation 15 ', the axially parallel Slots 16 '.
  • the drum roller 33 is cup-shaped here, so that from a suction channel 34 protrude into its open side can.
  • the suction channel 34 in this embodiment has the Inner wall of the drum roller 33 facing only one area opening 35 covering the perforation 15 'of the drum roller.
  • the width of this opening 35 corresponds to a first area 36 approximately the length of the slots 16 'of the perforation 15' of Drum roller 33 and tapers in a subsequent area 37th
  • the suction can also from go out a suction channel arranged outside the drum roller and work through the roller.
