Definitions

  • the invention relates to a device for equipping a denim fabric, which - starting from a raw material - is to be brought to predetermined target values of finished width, skew and weft density, with an expander, e.g. Hoist or Hotflue, which are associated with both extender for pulling the fabric and skew means for applying a skew, and with a continuous operation associated, preferably downstream, Krumpfstrom with compression means for adjusting a weft thread density.
  • an expander e.g. Hoist or Hotflue
  • Krumpfstrom Krumpfstrom with compression means for adjusting a weft thread density
  • the denim process chain in the manufacture of denim garments, e.g. so-called jeans, starting from the raw fabric includes the so-called denim finishing - also called fabric equipment. These include drying, longitudinal stretching and the so-called skew stretching as well as the shrinkage-making the fabric.
  • denim finishing - also called fabric equipment include drying, longitudinal stretching and the so-called skew stretching as well as the shrinkage-making the fabric.
  • Schrägrecken English: skewing
  • the fabric is pulled diagonally with respect to warp and weft (skew).
  • special Schrägereckwerke be used in practice.
  • Denim raw material is usually produced with a raw width, eg 162 cm, which is significantly larger than the finished width, eg 151 cm. To get the finished width, the raw material is pulled out. The thereby reduced weft thread density (number of threads per unit length) is then during upsetting of the web in a Krumpfstrom - especially with Gummibandkrumpfaggregat as Core machine - brought to the desired value. A measuring and control method with which the desired value of the shrinkage to be achieved is determined and given as a controlled variable the Gummibandkrumpfaggregat is out DE 43 23 715 A1 known. The residual shrinkage and the thread density per centimeter are directly dependent on one another for a given quality, ie if one knows the thread density at the exit of the finishing line, the residual shrinkage value is also given.
  • the pulling of a denim fabric web can be done in a conventional, a plurality of upper and lower rollers having stretching unit or, for example, in a loop dryer - Hotflue - if the latter has corresponding longitudinal stretching means.
  • a suitable hotflue is described in DE 33 36 328 C2 , It comprises an upper series and a lower series of guide rollers.
  • the two Leitwalzenserien are stored in the known parallel to each other and horizontally - essentially in one plane - in a housing.
  • the housing has in a inlet wall a horizontal inlet slot through which the fabric to be treated is spread out; accordingly there is an outlet slot in an outlet wall.
  • the (straight) connecting line between the inlet and outlet slots defines the central transport direction of the fabric in the hotflue.
  • the fabric web is transported in a loop or meander shape alternately over a lower and an upper guide roller.
  • tuyeres are provided, with the aid of treatment means, in particular heated air - to blow in general - circulating air - on the fabric or in the clamped fabric loops.
  • the fabric is kept within the Hotflue - with the help of the dryer upstream and trailing web tension means - below a predetermined fabric web tension.
  • This longitudinal tension should be at least so great that even with a goods content of thirty or more fabric meters a substantially wrinkle-free fabric flow within the Hotflue is guaranteed.
  • the aforementioned skew of the weft threads which is a significantly different from 90 ° oblique position of the weft threads relative to the warp threads of the fabric, is achieved when using a conventional stretching unit, for example by tilting a portion of the stretching rollers.
  • Most of the upper stretching rollers are raised on one side (at one longitudinal end) vertically or lowered the lower rollers on one side vertically.
  • An apparatus for equipping a denim fabric with an expansion device, which are associated with extender for pulling the fabric web, and with a downstream in continuous operation Krumpfstrom with compression means for adjusting a weft yarn density is off US Pat. No. 3,691,600 known.
  • This known device is provided with a measuring device for detecting the longitudinal shrinkage of the fabric web.
  • the invention has for its object to summarize in a plant an expansion device, such as horizontal bar or a Hotflue with connected spreader field (for adjusting the width of goods), and a Grummibandkrumpfaggregat (as a core machine for an adjustable longitudinal shrinkage) and to control the system so that for Residual shrinkage, skew delay and width decisive for the loss of goods remain reproducibly constant.
  • an expansion device such as horizontal bar or a Hotflue with connected spreader field (for adjusting the width of goods)
  • a Grummibandkrumpfaggregat as a core machine for an adjustable longitudinal shrinkage
  • the device for finishing denim fabric starting from a raw material preferably comprises a stretching device or a hotflue as the stretching device, wherein the stretching device is associated with both draw means for pulling the fabric and skew means for applying skew, and a continuous feed operation with upsetting means for Setting a (in particular a given) thread density.
  • the device comprises a single measuring device for detecting the actual values of fabric width, skew and weft density, which is in control in each case in control connection with the stretching and inclining means of the stretching device on the one hand and the compression means of Krumpfstrom on the other hand for adjusting the respective target values ,
  • the meter of the stretching device ie in particular the stretching unit or the spreader field of the Hotflue
  • the Krumpfstrom should be followed immediately. "Immediately downstream” here means that the fabric supply between the device to be controlled (stretching unit or Hotflue or Krumpfstrom) and the meter should be minimal in order to keep the amount of up to the switching of the control loop imperfectly treated goods small. The least loss of material in this sense, however, is to be expected if the meter is also the first fabric equipment stage - in general so the Reckwerk or the Hotflue - is preceded. Between the device to be controlled and the measuring device, aids, e.g. Web tension controller, are arranged.
  • the fabric width (at the expense of weft yarn density) and the skew of the weft yarns are set to a predetermined target value.
  • the weft yarn density previously reduced (during longitudinal stretching) is likewise brought to a predetermined desired value in the shrinking plant. Both steps are controlled according to the invention with the help of one and the same meter.
  • an optical detector with digital camera which can detect the thread density, the skew delay and the width of goods.
  • the detector should be performed traversing in his measuring and control work transversely to the transport direction of the fabric to achieve that he can also register the width of the fabric, the amount of skew and the weft density and enter into the associated control loop.
  • the measuring instrument is positioned on the fabric in front of the stretching device and before the shrinking system, all three parameters must be regulated forward. It is also within the scope of the invention, the meter at the end of the equipment line so following the Krumpfstrom, even immediately before winding, panels or the like, to install, so that the three parameters described above are all regulated backwards.
  • a denim material web 1 from roll 2 in the transport direction 3 is guided by a first tensioning means 4 into a hotflue with housing 6 designated as a whole by 5.
  • the housing 6 has a substantially horizontal inlet slot 7 with guide roller 8 and inside two series 9 of guide rollers 11 to the guide rollers 11, the fabric web 1 is guided in meandering loops upwards and downwards and finally via a guide roller 12 through an outlet slot 13 of the housing 6 passed to a second clamping means 14.
  • directed blowing nozzles 17 are provided in the - between each pair of guide rollers 11 of a series of rolls 9 clamped - fabric loops.
  • the longitudinal tension to be applied to the material web 1 within the hot-run 5 is adjusted between the two tensioning means 4 and 14 - in the direction of the central transport direction 18 of the material web 1 - by means of a longitudinal tension control device 19.
  • the upper guide rollers 11 are set at one of its longitudinal ends 21 in spherical bearings 22 and at the other of its longitudinal ends 23 mounted on a beam 24 which - as shown in FIGS. 1 and 2 - at its one longitudinal end of the 25th is held in a tilting bearing 26 and the other (in Brutransport therapies 2 subsequent) longitudinal end 27 on a tilting device 28 is resting.
  • the latter is assigned a tilt control unit 29.
  • In the transport direction 3 comes first the tilting bearing 26 and the longitudinal end 27 with the tilt actuator.
  • the measuring device 14 according to FIG. 1 is adjoined directly by a measuring device 30 according to the invention.
  • the transport direction 3 follows a Krumpfstrom 31 with shrinkage control device 32 and compression means 33.
  • the finished fabric can be wound on a roll 35 via a voltage regulator 34.
  • the fabric width, the skew and the weft yarn density are determined.
  • the device cost remains relatively low, if the measuring device 30 transversely to the transport direction 2 of the fabric 1, e.g. at a transversely to the transport direction 3 arranged rail traversing.
  • the values thus determined in the measuring device 30 are fed to the control devices 19 and 29 (longitudinal tension and skew delay) and to the shrinkage control device 32 along the dashed lines of action such that a corresponding control loop is created for adjusting predetermined target values.
  • the meter 30 of the Krumpfstrom 31 is connected upstream.
  • the meter can be followed by the Krumpfstrom.
  • a measuring device 30 ' which is preferably formed as well as the measuring device 30, shown in phantom in Fig. 1.
