Definitions
- the invention relates to an open-end spinning device according to the preamble of claim 1.
- DE 40 40 102 A1 shows a device for spinning a Thread, in which the sliver end by an additional Air flow is moved into the set, so that a effective resolution should still be possible if the speed of the opening roller compared to Rotor spinning devices usual speed of opening rollers is significantly reduced. Because the sliver end in the Is pushed in, combing is intensified, essentially through the side flanks of the teeth or Is caused. It is aimed in this way, too sufficient at slower combing speeds Generating friction, through which the fibers are made safe the sliver end or fiber beard are pulled out. It has it turned out, however, that by sucking the Individual fibers with the peripheral speed of the Opening roller are transported so that the individual fibers despite the reduced peripheral speed of the opening roller overall have the same speed as at conventional opening rollers and thus undesirably fast are.
- the generic DE 196 10 960 A1 describes a Open-end spinning process, in which the individual fibers on their Can no longer be slowed down from the sliver to the thread should.
- the individual fibers should immediately after their Detach from the sliver of a precisely defined one mechanically controlled speed.
- the feed device has a very wide feed roller and an equally wide opening roller. So that the number the interventions of dissolving elements in the fiber beard increase.
- the invention has for its object the fiber template for to improve the resolver.
- the spreading device required in relation to multi-stage drafting devices advantageously little space.
- a Generate fiber material template with a more precise dosage and increased uniformity of the amount of fiber fed can be achieved.
- the dissolving process itself will improved. Too high distortions in the direction of fiber flow and the result associated disadvantages can be avoided.
- the spreading device there is a compact device for effective spreading of the Sliver in the transverse direction in a narrow space. It can be one thin fiber material template for the opening roller generated be that over the entire working width of the opening roller enough. This means that the resolution process is flawless low opening roller speed as well as compared to that of Rotor spinning usual opening roller widened opening roller achievable, which is characterized by high dosing accuracy and high Characterized yarn uniformity.
- the distance between each interacting spreading rollers can be changed periodically.
- the tensile stress on the fiber material template acts change periodically and so the spreading process intensify, accelerate and equalize.
- a sliver can be 2 to 3 times, for example Width of the original width can be spread.
- a frequency of periodic change that is much higher is called the rotational frequency of the spreading rollers, the frequency preferably to a value between 8 Hz and 25 Hz is set leads to a high uniformity of the Spreading the fiber material template.
- the depressions can be designed as trapezoidal grooves his. Such a shape is easy to manufacture and it forms deflection edges for the between each interacting spreading rollers guided zigzag Sliver. The sliver is with between the deflection edges a tensile stress builds up, and under the Influence of this tension is effectively spread.
- the depressions and webs are designed so that the webs of the spreading rollers approximately one in the axial direction Form sinusoid. In this way, it is more gentle Spreading.
- the Spreading rollers formed by discs, each on a Shaft are attached, and the peripheral surfaces of the webs form.
- This version is simple and inexpensive produce.
- the limitation to a maximum of two slivers means that the fiber material template predominantly by cross expansion and not mainly due to longitudinal distortion to a thin non-woven fabric has been pulled apart when the opening roller is presented. This allows the uniformity of the Improve the fiber material template.
- a deflection device upstream of the belt spreading device is at such a distance for that from a jug stripped sliver arranged that the sliver at Pull out of the jug between the jug and the deflection device more than the length of the tape of a coil rotation hangs vertically.
- This arrangement enables the Coiler rotation incorrect rotation introduced into the sliver can turn out.
- Such false rotations consist of so-called S and from so-called Z twists, the can happen accidentally when you take off the tape. With the Belt spreading device associated deflection device can safely avoided that the wrong turns in the Break in pairs of spreading rollers and hinder the spreading process.
- a Sliver 1 pulled from the can 2 runs over the Deflection roller 3 of a deflection device 4 and is by a Guide 5 fed to a spreading device 6.
- the distance between the axis of the guide roller 3 and the can 2 a little more than the length of a coil turn.
- the Sliver 1 passes through three of the spreading rollers 7, 8, 9, 10, 11, 12 formed pairs of rollers and is in a spread state presented as a thin nonwoven fabric 13 of the opening device 14.
- the feed trough 15 presses the spread sliver 1 against the Feed roller 16 and forms a with the feed roller 16 Nip that the end of the sliver 1, the so-called Beard, holds back.
- the opening roller 17 combs the fiber beard and dissolves the sliver down to the individual fiber. there rotates the opening roller 17 in the direction of arrow 18.
- Die Fibers are taken over by a vacuumed take-off roller 19 and brought together into a narrow ribbon.
- the direction of rotation of the take-off roller 19 is indicated by the arrow 20 indicated.
- the take-off roller 19 and the pinch roller 21 form a clamping line that is traversed by the ribbon.
- the air spinning device 22 generates an air vortex which is used for Thread formation serves.
- Such air spinning devices are known for example from DE 196 10 960.
