Definitions
- the invention relates to a method and a device for producing a self-twisting yarn according to the preamble of claim 1 and claim 11, respectively.
- a generic device for producing such a self-twist yarn from the company Platt UK Limited is also known from the prior art (see, for example, service manual for the “Self-twist-spinner-type 888” from the company Platt UK Limited, Blacburn, England).
- the two games are brought together by means of union eyes, in order to generate a certain phase difference between the areas without rotation of the two games, one of the two games is first passed through a guide eye after passing through the wrong turning device and then directed onto the union eye which is merged with the other roving.
- the deflection of the one preamble via the deflection eyelet has proven to be advantageous, since any phase difference between the regions can be set without rotation or with less rotation between the two rovings. It has been shown that the strength of the resulting self-regulation strongly depends on the phase shift of the areas without rotation. In order to achieve a high yarn tenacity, a preferred phase difference of 30 ° is mentioned in the above-mentioned Platt manual. In the known devices, however, the roving threads often break, since these are subject to heavy wear due to the friction on the deflection and union eyes. This wear also leads to a reduced strength of the twisted self-locking game.

- FIG. 3A illustrative representation of two rovings from FIG. 2 and one self-twist yarn produced from these rovings by combining them without a phase difference;
- FIG. 3B Illustrative representation of two rovings from FIG. 2 and one from these rovings by combining them with a phase difference between the untwisted areas of self-twisted yarn.
- FIG. 4 top view of a device for producing a self-made game
- FIG. 5 Side view of the device of Figure 5;
- FIG. 6 advantageous embodiment of a device according to FIG. 4.
- FIG. 1 schematically shows a device for producing a self-made game.
- This device essentially comprises a drafting system 11 for producing two untwisted Vorgame 2 and 3, a false twisting device 4, through which the rovings 2 and 3 are periodically alternately given areas with S and Z twists, and a twisting device 12 in which the two twisted rovings 2, 3 are brought together so that they twist together to form a self-twisting yarn 1.
- the drafting system 11 is designed as a roller drafting system with two drafting rollers 13, 14.
- the wrong turning device 4 is a known Nitschel device. This has two essentially cylindrical nitsch rollers 7, 8 arranged parallel to the axis and rotating about their axes. The Nitschelwalzen 7, 8 rotate in opposite directions to each other and thereby promote the roving 2, 3 clamped between them. In addition to their rotation, the two Nitschelwalzen 7, 8 oscillate in the axial direction between two limit positions. As a result of this axial oscillation, the two rovings 2, 3 carried out are twisted and thus receive a rotation.
- the rovings are given an S twist in one direction of oscillation and a Z twist in the opposite direction of oscillation. Since the nitschel rollers 7, 8 stand at the reversal points of their axial movement, the Vorgame do not get any rotation at these times. Therefore, the alternating areas with S and Z rotations are separated by areas without rotation or areas with less rotation.
- false twist devices 4 shown in FIG. 1 with nitschel rollers 7, 8 false twist devices of the clamp type, as described for example in DE 198 27 870, or false twist devices which impart rotation to the rovings by air swirling (as, for example, in US Pat. No. 4,279,120 described).
- FIG. 3A shows a self-twisting yarn which was produced by twisting two pre-games 2, 3 together, the pre-games 2, 3 being brought together in such a way that the regions lie directly opposite one another, ie are in phase, without rotation.
- the rovings have a lower strength in the areas without rotation, the self-twist thread also has lower strength at these points.
- phase difference ⁇ is approximately 90 °.
- one of the two rovings 2 is guided onto the guide roller 6 via a deflection roller 5, as shown in FIG.
- the guidance over the deflection roller 5 causes the roving 2 to travel a longer way between the false twisting device 4 and the guiding point 13 than the roving 3, which is passed directly onto the guiding roller 6 after passing through the false twisting device 4.
- the longer distance that the roving 2 covers compared to the roving 3 determines the phase position ⁇ between the untwisted areas.
- FIGS. 4 and 5 show the design and arrangement of the rollers 5 and 6 in more detail.
- the two rollers 5 and 6 are rotatably supported, their axes of rotation being perpendicular to the plane spanned by the two rovings 2 and 3.
- the guide roller 5 is in the The embodiment of FIG. 4 is further away from the false twisting device 4 than the guide roller 6. After passing through the false twisting device 4, the roving 2 is first guided over the deflecting roller 5 and then passed onto the guide roller 6.
- the rollers 5 and 6 are designed as disk-shaped cylinders, a guide notch 14 being formed in the cylinder jacket to improve the guidance of the rovings 2, 3.
- the guide notch 14 prevents the rovings 2, 3 from slipping sideways from the guide surfaces 5a, 6a of the rollers 5, 6.
- the merging of the two examples 2 and 3 takes place at the merging point 13 on the guide surface 6a of the guide roller 6.
- the distance between the axes of rotation 5b and 6b of the rollers 5 and 6 can be used to set the additional path that the roving 2 has to travel between the false twisting device 4 and the merging point 13 compared to the other roving 3.
- the rollers 5 and 6 are mounted so that their axes of rotation 5b and 6b are mutually displaceable in the plane which is spanned by the two rovings 2 and 3.
- the two rovings 2, 3 run essentially parallel to one another in the area of the false twisting device 4 and in the area before being guided over the deflection roller 5, the roving 3, which is not guided over the UmlenlcroUe 5, runs in the area between the false twisting device 4 and the merging point 13 in the same direction as the twisted self-twisting thread 1.
- This course of the Vorgame 2 and 3 before merging enables a twisting without the Vorgame underneath Stand tension or can get caught on the guide roller 6. This results in a constant distance between the untwisted zones of the first games 2 and 3 in the twisted self-game 1.
- the twisted self-twisting thread 1 can be guided in the thread running direction after the merging point 13 via a rotatably mounted pressure roller 10. This enables clean and spam-free guidance of the twisted self-winding game 1.
- the roving 3, which is not deflected via the deflection roller 5 can be guided in the yarn running direction C before the merging point 13 via a pressure roller 9 onto the guide surface 6a of the guide roller 6. This ensures an exact and tension-free guiding of the roving 3 onto the guide surface 6a.
- a tension-free arming of the pre-games 2 and 3 contributes significantly to the improvement of the yarn strength of the self-threading game 1 and also causes a constant distance of the untwisted zones over the length of the self-threading game 1. This in turn improves the properties of fabrics woven with such self-twist yarns 1 in terms of their strength and in terms of their visual impression.
- the present invention has the advantage that the Vorgame cannot be worn or damaged by the deflection and the merging.
- the rovings 2, 3 will wear due to the friction of the yarns on the eyelets before they are brought together to form the self-twist yarn 1.
- the rovings 2, 3 can also get caught in the eyelets, as a result of which thread breaks often occur during the manufacturing process. This leads to frequent and undesirable interruptions in the manufacturing process.
- a hooking of the pre-games 2, 3 in the eyelets can lead to an unevenness in the distance between the untwisted zones in the self-review 1. This results in an unfavorable appearance of fabrics woven with such self-twist yarns.
