Definitions

  • Threads or twisted threads are usually produced in multi-stage processes, the known processes and devices essentially comprising the following individual steps or individual features:
  • slags are fed to a ring spinning spindle by means of a drafting device, on which the filaments are wound on bobbin tubes.
  • These bobbins - in the main case copes - are rewound in a second step on a winder to form cross-wound bobbins.
  • two or more packages are wound on a specialist machine.
  • the specialist packages are then presented, for example, to a double-wire twisting machine in order to produce a finished twine.
  • the double-wire twisting spindle can also two cross-wound bobbins of the winding machine for producing a finished thread are presented directly.
  • Spun threads are produced using the open-end spinning process and wound onto tubes to form packages.
  • two or more of these cross-wound bobbins are rewound in a subsequent process on a specialist machine to form a cross-wound bobbin.
  • the cross-wound bobbins are then presented either twice or, in the case of the specialist cross-wound bobbin, as a single bobbin for twisting a double-wire spindle.
  • a yarn bobbin is attached to a hollow spindle, which previously e.g. has been produced on a conventional ring spinning spindle.
  • a roving coming from a roving supply for example a slip-on creel, passes through a normal drafting system and is inserted into the hollow spindle axis together with the spinning thread of the yarn bobbin previously placed on the hollow spindle.
  • the yarn of the bobbin is unwound during the spindle revolutions and runs together with the drawn roving through the hollow spindle to a winding unit or a winding station, as e.g. in "A new spinning twister" from "Melliand textile reports 12/1966", pages 1354 and 1355.
  • DE 42 35 433 A1 describes a method for producing a twisted thread, in which, in a first step, a roving drawn off from a roving supply and guided through a drafting device is spun in a ring spinning process and thereby permanently attached to a hollow spindle Yarn carrier is wound into a spun yarn body; In a second phase, the spinning process is interrupted and the spun thread previously wound up to form the spinning yarn body is drawn off from the spinning yarn body with balloon formation and, together with the roving further drawn from the roving stock and stretched in the drafting device, is guided through the hollow axis of the hollow spindle and fed to a winding unit, whereby the hollow spindle is set in rotation in dependence on the delivery speed of the friction roller of the winding unit in such a way that the rotation of the spinning thread is turned back again.
  • the twisting stage works with a strand of yarn that has spinning twist and a second strand of yarn that runs in as a fiber slub.
  • the invention has for its object to provide a combined spinning-twisting method and a corresponding device with which it is possible to obtain any level of twist between the single strands or single threads on the one hand and the twist on the other hand in the finished twine . Threads of this type, that is, with a not completely compensated spinning twist, are predominantly used.
  • a method with the features of claim 1 and a device according to claim 2 serve to achieve this object.
  • the main idea of the present invention consists essentially in ring spinning devices which are known per se and which are also known per se Equip hollow spindles and arrange two of these ring spinning devices one above the other, so that the two spinning threads produced on these two ring spinning devices by the ring spinning process are then drawn off with rotating spindles with balloon formation through the hollow axes of the same and wound below the lower hollow spindle, for example to form a twisted cheese package.
  • the most varied rotation ratios between the individual spun threads on the one hand and the thread twist of the finished thread on the other hand can be achieved, for example also by the fact that the two spindles arranged one above the other are driven at different speeds.
  • the equipment required for the construction of the spun yarn packages correspond to the usual elements of a ring spinning machine, the ring bench movement being controlled centrally, as usual, in order to produce the desired packages.
  • the ring bench movements are interrupted for the subsequent twisting process.
  • the spun threads previously wound into the spun yarn packages are pulled off the yarn carriers with balloon formation and fed to the winding unit through the hollow axes of the two hollow spindles.
  • the friction roller of the take-up unit works depending on the spindle speed at such a speed (take-off speed) that the rotations of the individual filaments are either wholly or partially turned back.
  • Figure 1 shows a schematic representation of two stacked ring spinning devices with hollow spindles and a downstream thread winding unit during the spinning process representing a first step.
  • Figure 2 shows a schematic representation of the same device during the twisting process carried out in a second step.
  • each ring spinning machine contains a spindle bank 2 or 2 'for the storage of hollow spindles 3 or 3', of which only one hollow spindle is shown in the drawing for each ring spinning machine.
  • the individual hollow spindle 3 or 3 ' comprises a spindle hollow axis 4 or 4' with drive whorls 5 or 5 ', around which a spindle drive belt 6 or 6' is placed, which is connected to deflection and / or tensioning rollers 7 or 7 'and a drive pulley 8 or 8 'is guided, each on a centrally driven shaft 9 or 9 'is attached.
  • Ring holders 10 and 10 ' which can be moved up and down in the direction of the double arrows f1 and f1' and are attached to a ring bench (not shown), carry spinning rings 11 and 11 'for the ring travelers 12 and 12' which are customary in ring spinning machines.
  • Each hollow spindle 3 or 3 ' is assigned a roving body, for example a flyer spool 13 or 13' or a feeder bobbin, which represents a roving supply.
  • the roving a or a 'coming from these flyer bobbins 13 or 13' is drawn off while the hollow spindle 3 or 3 'is running and stretched by means of a conventional drafting unit 14 or 14' before passing through a thread guide lying in the extension of the hollow spindle axis 15 or 15 'is rotated when the spinning ring 11 or 11' moves up and down and is wound up to form a spinning yarn body 16 or 16 '.
  • a winding mechanism 17 which comprises a bobbin holder frame 18 for holding a bobbin tube, a drive roller 20 which can be driven by means of the shaft 19 and a traversing thread guide 21, as is known, for example, in the winding mechanisms of double-wire twisting spindles.
  • the traversing thread guide 21 can be driven back and forth in the direction of the double arrow f2 (see FIG. 2) by means of the traversing rod 22.
  • spinning yarn bodies 16 or 16 ' have been wound up by means of the spinning process which represents a first working step, the spinning process is interrupted, the drive of the ring holder 10 or 10' being stopped according to FIG becomes.
  • the spun yarns b and b 'previously wound into the spun yarn bodies 16 and 16' are then drawn off from the yarn bodies 16 and 16 'with the formation of a balloon in a second step, the spun yarn b drawn off from the upper spun yarn body 16 first through the hollow spindle 3 and then, together with the spinning thread b 'drawn off from the lower spun yarn body 16', is passed through the lower hollow spindle 3 'before both are then wound up as twisted thread c to form the cross-wound bobbin 24 driven by the drive roller 20.
  • the hollow spindles 3 and 3 ' are rotated by the drive belt 6 or 6' acting on the respective spindle whorls 5 and 5 'depending on the take-off speed of the winding unit 17 in such a way that the spun threads b and b' during the spinning process granted rotations can be reversed either in whole or in part.
  • the solution according to the invention consists in using, during the spinning processes carried out on ring spinning devices, a permanently attached yarn carrier installed on hollow spindles for the construction of spun yarn bodies 16 or 16 ', from which the spinning yarn components are drawn off again during the subsequent twisting process and through the hollow axes the rotatingly driven hollow spindles are guided to a winding unit.
  • a permanently attached yarn carrier installed on hollow spindles for the construction of spun yarn bodies 16 or 16 ', from which the spinning yarn components are drawn off again during the subsequent twisting process and through the hollow axes the rotatingly driven hollow spindles are guided to a winding unit.
