Definitions

  • the invention concerns the method of sliver feeding in production of fancy yarn on spindle-less rotor machines with sliver feeding by a feed roller to the stripping roller, stripping individual fibres from the sliver that are consequently used at the spinning rotor for yarn spinning plus spinning units for this method performance.
  • the sliver feeding from staple fibres is performed using a feed roller, to which the sliver is pressed using so called table.
  • the side of the table adjacent to the feed roller is covered with an extremely smooth surface with low friction in relation to the fibre material, while - on the other hand - the feed roller is covered with high-friction surface caused by corrugation or other type of roughing - that means that while turning, it takes along the fibre material which is supplied in a constant speed to the stripping roller and in the location of a contact with the stripping roller, the yarns from the sliver are combed out in so called combing zone and then they are transported - usually by air via transport channel - to the spinning unit, where yarn is spun from the fibres.
  • the feed roller is usually turned by a central drive via a clutch that is disconnected in case of any break. The clutch connects at the time of spinning on.
  • fancy yarn is requested for production of fashionable goods.
  • fancy yarns There are several types of fancy yarns. One of them is characterised by the fact that there are sudden increases or reductions of the yarn diameter in regular or irregular intervals - it is a kind of an artificial fault, in other words these are local changes of the length weight of the yarn. Then, such yarn creates characteristic patters in the fabric or knitted fabric, depending on structure and "fault" character.
  • the task of the invention is to significantly reduce the effects of such filtration in case of sliver feeding at spindle-less spinners and to allow high-quality spinning of fancy yarns even on spindle-less rotor machines, corresponding with quality of fancy yarns produced on annular machines.
  • the task is - to a significant level - solved by using the method of fancy yarn production on spindle-less spinners with feeding of a sliver of staple fibre material or staple or a mixture of the materials, by the feed roller to the stripping roller, where individual fibres are combed out of the sliver and consequently spun in the spinning rotor into the yarn, in compliance with this invention, the base of which includes mainly the fact that in case of any change of the yarn spinning profile, there occurs a short term sudden increase - in the time interval of 0,01 - 0,9 second - of the sliver supply in at least 10% above the operation speed, while the sliver section fed in higher speed is separated from sections spun under operation speed in at least one place - at the beginning or in the end - by reversing the sliver feed in the time interval of 0,01 - 0,9 second by a speed that exceeds the operation speed of feeding.
  • the limit value is the area of return, characterised as 90% of the average staple length - sliver returning should not exceed the above stated size.
  • the sliver movement reversing to be completed with short-time interruptions of sliver feeding in the time interval of 0,01 - 0,9 second.
  • Fancy yarn may be advantageously produced on spinning unit of a spindle-less spinner, base don the fact that the control unit of the feed roller is connected with the yarn break sensor and programmable control unit.
  • FIG. 1 a simplified scheme of the spinning unit
  • Fig. 2 showing the course of sliver feed speed when creating the fancy yarn with sliver movement reversing
  • Fig. 3 shows the course of sliver feeding when the high-speed fed section is separated at the beginning of its creation from sections fed in operation speed by feed reversing and - in the end - by a delay in feeding
  • Fig. 4 shows the course of sliver feeding when creating the strengthening in steps.
  • a schematically drawn spinning unit 1 of the spindle-less spinner which - as it can be seen in Fig. 1 - includes the feed roller 3 driven directly by step electric engine 5 or via electro-magnetic clutch 6 .
  • the feed roller 3 is continued by a stripping roller 4 driven by a belt 14 , inter-connected with channel 7 with the spinning rotor 8 .
  • the spinning rotor 8 is driven by a belt 18 .
  • the output from the spinning rotor 8 is performed by a tube 9 , followed by the break sensor 10 .
  • the break sensor 10 is connected with the control unit 11 of the drive of the feed roller 3 , controlling the operation of the step electric engine 5 in case of individual drive or the electro-magnetic clutch 6 in case of central drive.
  • the control unit 11 is also connected with a programmable control unit 12 , which is also connected with other not-shown controlled units of the spinning unit 1 .
  • the drive is equipped with a suitable reversing box or every spinning unit 1 is equipped with a reversing and speed box, which is well known and it is not shown as well as the other parts that are not necessary for the invention explanation - like e.g. the drawing-off, wind-up and spinning units.
  • the spinning unit 1 - when continually producing the yarn 13 - feeds the sliver 2 by a constant speed and after its unification the air arranges transport to the spinning location rotor, where spinning into yarn 13 is performed.
  • the production of fancy yarn 13 characterised by changes in profile of the yarn 13 regularly or irregularly distributed along its length, will be explained by using schemes with time data marked on the horizontal axis and feed roller 3 revolution speed data marked on the vertical axis, the total time of the effect is marked Lef , permanent operation speed Vp , increased speed Vmax , reversing speed Vr , Vr ', Vr ", Vr ''', reversing time Lr1 at the beginning of accelerated feed and reversing time in the end of the sliver 2 feed supply in an accelerated speed.
  • the sliver 2 is fed by operation speed Vp , i.e. under permanent - i.e. standard case.
  • operation speed Vp i.e. under permanent - i.e. standard case.
  • the reversing time Lr1 is set within the range of 0,01 - 0,9 second, depending on reversing speed Vr , which should be as high as possible and it is advantageously selected at least twice higher in comparison with the operation speed Vp .
  • the materials that can be reversed to a bigger extent are an exception, while - from the point of view of resulting effect - any more extensive reversal of the sliver 2 does not bring any other positive effects.
  • Effect termination for limitation of final combing and other transition features - if it is to be apparent - is performed by reversing the sliver 2 feeding for the period of Lr2 .
  • This sliver 2 reversal is appropriately affected by all and any facts stated in the course of reversing description at the beginning of the effect creation.
  • the length of the effect Lef - i.e. the length where the change of the yarn 13 profile is directly performed - follows the term of duration of the sliver 2 feeding in an accelerated speed Vmax and the yarn 13 strengthening that occurs follows the extent of accelerated speed Vmax . It is apparent that the accelerated speed Vmax is different for individual spinning types, depending on character of fibres 22 used. Also the strengthening can not be selected at will.
  • the strengthening is set mainly by mechanic features of fibres 22 and by their ability to withstand the increased load when pulling the strengthened section of the yarn 13 from the spinning rotor 8 .
  • Exact setting of accelerated speed Vmax within the above stated range must be tested, so as the spinning process is not interrupted by breaks and so as the yarn 13 obtained is of high quality.
  • the appearance of the final effect may be significantly affected by control of the individual stages of feeding and by reversing the sliver 2 .
  • the scheme 2 shows the course of sliver 2 feeding for reaching a gradual setting of the effect.
  • the scheme shows an example of the effect course with two differently following strong profiles of the yarn 13 , when the sliver 2 is fed by various and mutually accelerated speeds Vmax ' and Vmax " and reversing is also performed by different speeds Vr ', Vr " and Vr ''', while one reversing Vr " is included between the accelerated speed Vmax ' and Vmax ".
  • the invention is designed for spinning on spindle-less rotor spinners.
