Definitions

  • This invention principally belongs to the technical field of textile fabric weaving. More particularly, it is related to a new and useful method to prepare weft yarn spools filled with indigo dyed yarns, in order to supply weft yarn to a conventional weaving loom.
  • the invention further con- cems a new and useful apparatus to implement the method of this invention.
  • This manufacture comprises, as it is familiar to the man skilled in the art, the indigo dyeing of warp yarns, be it in the so-called slasher dyeing process or in the chain-dyeing process, and the weaving into denim with undyed or bleached cotton threads as weft yams.
  • U. S. patent no. 2,889,120 describes and claims a machine for winding a series of sewing machine bobbins or self-sustaining cops.
  • British patent specification no. 340,978 describes a warp beam for the treatment of artificial silk.
  • British patent specification no. 645,591 teaches improvements in sectionalized yarns beams for warp yarns. Still other publications describe the winding of other mechanical treatments of warp yarns.
  • Another object of the invention is to provide a method as set forth above which allows an economical work free from time consuming breakdowns, for example due to yarn ruptures, and free from avoidable wastes.
  • Still another and equally significant object of this invention is to provide a simple but perfor- mant apparatus which allows to implement the new method and which produces weft yarn loom spools filled with indigo dyed yarn, in excellent yields and without substantiel waste.
  • the invention allows for the first time to produce weaving loom spools wherein an indigo dyed weft yarn is wound on flange bobbins or disk spools.
  • the basic idea of the invention is to collect a weft yarn from indigo dyed warp yarns.
  • warp yarns with an indigo vat are known per se, see, e. g. Swiss patent specifications nos. 612, 557 and 613, 333 and the article by P. Richter in « Textilveredlung » 1975, pp. 313-317.
  • These publications teach that warp yarns may be indigo dyed in one of two processes called « chain dyeing » and « slasher dyeing » respectively.
  • the chain dyeing comprises the forming of yarn cables from about 300 to 400 individual warp yarns, and several cables are dyed simultaneously and in horizontal relationship to each other in the indigo vat liquor, air passages of the cables for the oxidation of the indigo being introduces between sequential vat passages.
  • the cables are then rinsed, dried and warped.
  • the dyed yams are beamed on a warp beam in the future warp ccnfiguration, i. e. in the form of several thousands of parallel warp yarns wound up in succeeding « layers
  • the invention has the object to develop weft yams from this winding too.
  • This object may be attained, according to the invention, by introducing additional yams, in the amount necessary for the weft, into the set of warp yarns before the dyeing step, to recover them after the dyeing, and to wind them up, separately from the warp yams but simultaneously and, of course, with the same speed.
  • Another embodiment of this method is to form the warp beam as described above, without separating the weft yams, and to recover the weft yams on the said flanged weaving spools during a subsequent rebeaming of the original warp yarn beam obtained after the dyeing step, said rebeaming and recovering of weft yarns may be effected twice or even more often.
  • Figure 1 shows schematically a side view of a system for the indigo dyeing of warp yarns following the principle of the slasher dyeing, however comprising means for the separate manufacture of weft yarns.
  • the drawing is most simplified and is only intended to show the general procedure of this invention.
  • the indigo dyeing machine is designed as 60 and the subsequent devices for washing, optional aviving and drying are designed as the field 62.
  • the warp yarn to be dyed is typically unwound from the warping beams 64 and 66. Then the warp yarns are combined, dyed, worked up and divided and separately wound up on two weaving beams 68 and 70.
  • This method is known, see for example the Swiss Patent specification no. 612, 557 already mentioned above.
  • a further yarn beam 72 is provided which supplies weft yarns in such a manner that the horizontal distance between two weft yarns is about 50 mm.
  • weft yarns are now treated together with the warp yams in the machine 60, 62, are separated when leaving the machine, by the device 73 from the upper warp yarn layer 74, and finally wound up separately on flanged weaving spools 42. These weaving spools 42 can thus immediately be used without rebeaming, as a weft yarn supply.
  • the weft yarns may also be provided with lesser horizontal distance.
  • the number of weft yarns should not exceed three times the number of the flanged weaving spools on the spool shaft.
  • deflecting means must be used, for example eyelet bars (not shown).
  • figure 2 schematically shows a side view of a device for providing weft yarns from warp yarns.
  • the warp beam 80 comprises warp yarns which have previously been indigo dyed. in a slasher dyeing machine.
  • the parallel yam layer 82 is now rebeamed in the direction shown by arrows 84, goes about deflecting rollers 88, 90 and 92, and is wound up on the empty beam 86.
  • the driving and spreading means are not shown in these Figure.
  • individual threads are removed by separating rollers 43 and wound up on flanged weaving spools 42 which are fixed on ten shafts 44.
  • the number of the individual threads thus removed (E) is therefore a total of if B is the width of the yarn layer 82 and b that of the weaving spool.
  • spools 42 fixed side by side on the shaft 44.
  • the shaft 44 is driven by a hydraulic motor (not shown).
  • a winding force of about 70 N when yams with a titer of about NE 12 are used) is maintained ; the hydraulic motor should therefore provide a constant torque.
  • Each flanged weaving spool 42 receives for winding an individual yarn whose length is about 10 000 m.
  • the winding up is preferably begun in pinching the leading end of yarn between two flanges of adjacent spools. This beginning is the trailing end when the spool will be filled. This trailing end is therefore, directly accessible and can be joined to the normal leading end of the next weaving spool so as to avoid any interruption during the weaving process.
  • Figure 3 shows a central sectional view of a flanged weaving spool used in the method of this invention.
  • the spool 42 is composed of two parts which are preferably each manufactured by injection molding from a thermoplastic synthetic resin, namely the inner portion 52 and the outer portion 54.
  • the dimensions of the radial flanges and the axial hub are selected so that the shape represented in Figure 3 is obtained when the two portions are put together ; then, the two portions 52 and 54 are cemented together with the cylindrical contact surfaces 56 and 56' and form thus a compact and a solid spool body.
