Definitions
- the invention relates to a method for producing a textile Yarn, in which by means of an opening roller from a Fibrous dressing sucked individual fibers onto a fiber collecting surface perforation associated with a suction source has and continuously a solidified and removed by turning Forms yarn from parallel and stretched fibers, and an apparatus for performing such a method suitable is.
- the channel is separated by the gusset between two interacting axially parallel, perforated and by a suction acted upon, co-rotating rollers formed, between which the yarn is created.
- the object of the invention was to remove the fiber bundle from the fiber collecting surface to improve. It solves them Task procedurally in that on the fiber collecting surface deposited fiber package without rotation as a fiber sliver from the Deposit area discharged and only in a subordinate Area of twist is solidified by twisting into a yarn.
- the object of the invention is thereby achieved solved that the fiber collection surface as in the direction of movement the fiber sliver is formed around its surface Circumference has a narrow strip of perforation and the area of which the fibers gather over one with a Suction source connected suction channel that runs in its the rotating Area facing area with at least one opening is provided with the perforation of the circumferential Covering area and that the surrounding area is a device for Granting rotation is downstream.
- 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, which 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 bodies and that Inlet roller pair of such a drafting system is bypassed, the extremely slow rotation speed lead to inconsistent running can.
- the opening of the suction channel can be a through opening or also designed as a perforation in the form of holes or slits be. 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 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, which 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 resolved, occasionally freely requested.
- 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 of one lying inside the apron 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 Slots 21 is made.
- the perforation 20 of the suction channel 19 is designed as elongated slots, even for 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 one that is familiar from 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 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 pair of rollers 23 to the ring spindle 24.
- the fibers are stored roof tile-like to the endless fiber sliver 32 together.
- the ring spindle 24 issued by the pair of rollers 23 delivered without rotation Fiber sliver 32 twist and winds the yarn thus formed 26 on the cops 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 37.
- the suction can also from go out a suction channel arranged outside the drum roller and work through the roller.
- the drum roller is then on the inside of its peripheral surface with a non-rotating Mask covered only in the area of the suction channel and Functional openings in the area of the fiber collecting surface having.
- the drum roller 33 is as in the embodiment of FIG. 1 to 3 a pressure roller 22 associated with the drum roller forms a pair of rollers 23 '. Also one downstream of the pair of rollers 23 ' Ring spindle 24 corresponds to that in connection with those Figures described.
- the resolution device 1 When the device is operating, the resolution device 1 individual fibers 11 by the suction of the pressure sink, through the opening 35 of the suction channel 34 and the perforation 15 'of the drum roller 33 acts in the fiber channel 10 the perforation of the drum roller sucked. They camp there in the area 36 due to the slot shape of the perforation 15 'in a comparatively wide fiber package 31 '. If the Slots 16 'of the perforation 15' of the drum roller 33 through the Rotation come in the area 37 in which the width of the opening 35 decreases in the suction channel 34, the fiber bundle 31 'is increasing contracted to the width of the opening and narrow Fiber fuse 32 narrowed. This fiber sliver 32 is by the pair of rollers 23 'discharged from the sliver formation zone and then rotated and wound by the ring spindle 24.
- FIG. 4 and 5 accordingly from a first area 36 in which a wide Fiber package 31 'is formed and a subsequent area 37, in which the broad fiber package forms a narrow fiber sliver 32 is narrowed and narrowed.
- This division of the sliver formation zone into an accumulation area 36 and a compression area 37 is in particular with thick slivers of fiber many fibers in cross-section advantageous.
- FIGS. 1 to 3 This division of the sliver formation zone into an area 36 for Forming the fiber package and an area 36 for summarizing the fiber sliver is also in the embodiment of FIGS. 1 to 3 possible.
- the strap 12 ' is extended, so that it extends over the two areas 36 and 37 can.
- the perforation 15 of the straps 12 'in this Trap multiple, adjacent rows of holes 16 or but slots like the drum roller 33 of Figs. 4 and 5 on and the length of the slots 21 of the perforation 15 of the suction channel 10 in the direction of the strappy 12 gradually decreases to thus bringing together the fiber sliver 32 '.
- Fig. 3 it is also shown that the deflecting effect of the deflecting roller 14 of FIGS. 1 and 2 also by a rounded edge 38 of the suction channel 19 can be achieved.
- the density of the perforation 20 in the suction channel 19 increases, i.e. the mutual distance of the slots 21 in the direction the discharge of the fiber sliver 32 can decrease. Thereby acts in this area a higher suction, the higher Flow resistance of the increasingly denser towards the outlet Compensate fiber packs and approximately the same suction effect to ensure the fibers 11.
- the fiber package and the Fibrous sliver-forming organs can also be arranged so that the The fiber collecting surface is at the bottom and the fibers are attached to it from below be sucked in. This has the advantage of a casual break-in the sliver 6 and lower height.
