Definitions

  • This invention principally belongs to the technical field of weaving textile fabric. 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 concerns a new and useful apparatus, as well as a particular weft yarn disk bobbin, 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 yarns.
  • 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 performant 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 substantial waste.
  • a still other object of this invention is to provide a new disk spool for use as a final yarn receiving bobbin, to be used in the method and the apparatus of the invention for being filled with indigo dyed weft yarn.
  • 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.
  • individual weaving spools filled with indigo dyed weft yarns can be manufactured starting from windings of warp yarns on a cable spool, or a warp beam, if, according to the invention, said plurality of yarns is first wound up simultaneously on a series of intermediate spools, each of said intermediate spools receiving a group of yarns comprising the same number of individual yarns, and the yarn group on each intermediate spool are then separated, in a second step, into individual yarns, and each yarn such obtained is wound up individually on a weaving spool.
  • a plurality of weaving spools are preferably arranged on the same, substantially horizontal shaft.
  • the auxiliary spools i.e. the intermediate spools which receive the said yarn groups are preferably arranged side by side on a common shaft.
  • these spools are filled by the wound up yarn groups which groups have been formed by separating the starting yarn cable into strings each of which being composed of the same number of yarn threads, the auxiliary spools are removed from their common shaft, the individual yarn threads on each spool are identified and separated, and each yarn is wound on a flanged weaving spool, all weaving spools necessary for this final step being preferably also mounted side by side on the same shaft.
  • each rewinding step is selected in such a manner that they are comprised within + 25 % of the same value.
  • the dividing factors are defined as the product of spool width, spool count and yarn speed during each step of the method. This will be explained in detail later.
  • the auxiliary spools are typically arranged side by side on a common shaft and fixed thereon, e.g. by lateral clamping with the aid of screw nuts, or by means of a driver such as a key and key way pair, or both.
  • the individual auxiliary spools which hold each about 10'000 m of.yarn, multiplied by the number of yarns per spool, are preferably metal (aluminium alloy) spools having a hollow cylinder as a core and plane parallel circular plates as flanges.
  • the spooler frame In the second step of the method of this invention, it is not possible to use a conventional spooling frame since the tensile forces of the individual threads on the intermediate spool are very different. Thus, if a conventional spooler frame is used as such, there are always yarns which break. Hence, the spooler frame must be equipped with a rather complicated electronic device for a gradual increase of the spooling speed together with an electronic braking device for gradually changing the braking force of the intermediate spool, both devices being connected by computing and control means.
  • This invention is therefore related furthermore to a special, particular flanged weaving spool which can be used in the method of this invention but which has still its own use.
  • This weaving spool is made of a synthetic resin and comprises a first integral halfspool having an axial, hollow-cylindrically shaped bush and a radial circular ring flange, and a second integral half-spool also having an axial, hollow-cylindrically shaped bush and a radial circular ring flange, said second half-spool bush having the same length as said first half-spool bush plus the thickness of one flange, but an outer diameter fitting in with the inner diameter of said first bush, said two half-spool bushes being cemented or welded together.
  • the number of flanged weaving spools which are necessary to carry out the second step of the method of this invention in its first principal embodiment, are slipped, one after another, on a suitable driving shaft, without using intermediate washers, and then clamped together and fixed with the shaft.
  • the shaft is then driven preferably by a hydraulic motor which can be adjusted such as to supply a winding-up force of from 40 to 150 mN (per yarn), multiplied by the number of the yarns to be wound up (this is, the number of weaving spools per shaft), preferably 50 to 80 mN per yarn.
  • the working speed which has been obtained amounts to up to 200 m/min in the first step where the yarns are wound up on auxiliary spools, and typically 300 m/min in the second step, i.e. the winding on weaving spools, or even more.
  • the flanged weaving spools are preferably made from thermoplastic, resistant, well workable and smooth synthetic resins such as nylon, polyester, ABS (acrylonitrile butadien styrene copolymer), polycarbonate or other polymers or copolymers.
  • thermoplastic, resistant, well workable and smooth synthetic resins such as nylon, polyester, ABS (acrylonitrile butadien styrene copolymer), polycarbonate or other polymers or copolymers.
  • the dyed warp yarn When the dyed warp yarn has been obtained by the slasher dyeing method, the dyed yarns are beamed on a warp beam in the future warp configuration, i.e. in the form of several thousands of parallel warp yarns wound up in succeeding "layers".
  • the invention has the task to develop weft yarns from this winding too.
  • the object is attained, according to the invention, by introducing additional yarns, 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 yarns 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 yarns, and to recover the weft yarns 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 a cable bobbin 10 having an indigo dyed yarn cable 12 wound up thereon.
  • the process of indigo dyeing does not be a part of this invention and is know as such to the man skilled in the art.
  • the invention is not limited to the application of the indigo dyeing of fiber bundles or other arrangements of yarns; is may be implemented at all instances where weft yarns should be recovered form warp yarns.
  • the cable 12 is a composition of 416 indigo dyed individual yarns of cotton having a titer of from about 7.5 to 16 NE, typically about NE 12 for denim.
  • the length of the cable amounts to about 10'000 m.
  • This cable should now be opened and simultaneously divided into 13 beams having 32 yarns each. These figures have been selected since the second, subsequent rebeaming will be effected twice as rapid as the first one, and since the second rebeaming should give 42 individual rebeaming spools, a higher number of spools would thus necessitate an asymmetric requirement of space which will be explained later.
  • Groups 14 having 32 yarns each are produced by the grid 16 which receives at the beginning of the rebeaming work corresponding yarn bundles divided by hand. At least one second grid 18 further smoothens the yarn sheaf 14, only one second grid 18 being shown. Instead of the grids, other known separating and smoothening devices may be used.
  • the individual yarn sheaves 14 having 32 yarns each, are simultaneously wound up on auxiliary spools 20.
  • the auxiliary spools 20 are secured to a shaft 22 with blocking means 24.
  • the second stage of the rebeaming method is represented as a device schematically shown as a top view.
  • An auxiliary spool 20 is fixed on shaft 30 which may be slowed down, as necessary, by a braking device (not shown).
  • the wrapping 32 on the spool 20 which is composed of a group of 32 yarns having a length of each about 10'000 m, is divided in the grid 36 into 32 single yarns 34 which are conducted by the eyelet bars 38 and 40 to the flanged weaving spools 42.
  • the shaft 44 is driven by a hydraulic motor 48, and the inlet and outlet of hydraulic flow medium is designed as 50.
  • a winding force of about 70 N when yarns with a titer of about NE 12 are used
  • the hydraulic motor 48 should therefore provide a constant torque.
  • Each flanged weaving spool 42 receives for winding an individual yarn whose length is about 10'000 m, and there are 42 spools side by side on the shaft 44; in FIGURE 2, only the two outermost spools 44 are shown.
  • 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 of this invention. This construction is not yet known, and it was surprising that such spools can be used on looms.
  • 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.
  • the widths of the auxiliary spools of the first step is 175 mm, the spool number is 13 and the advancing speed of the thread is 200 m/min. This will give a working product of 4,55 x 10 5 mm.m/min, whereas for the second step (spool widths 50 mm, spool count 42, advancing speed 300 m/min) a working product of 4.8 x 10 5 mm.m/min is calculated. If the advancing speed of the second step becomes greater which is normally possible, the man skilled in the art therefore receives the teaching to increase the spool number in the first step to 14, for example, and to decrease that of the second step to about 30.
  • the thread count in the cable which may generally be selected at will, is then increased to 14 x 13 420.
  • the working products are then the following: when the advancing speed in the second step is selected to 325 m/min; the best advancing speed may also be calculated in first calculatig P 1 in putting P 2 equal to P 1 and finally calculating V 2 which is the advancing speed of the second step.
  • P 1 and P 2 symbolize the working products in the first and the second step, respectively.
  • FIGURE 4 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 intented 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 yarns in the machine 60, 62, are separated when leaving the machine 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 (which are shown in FIGURE 4).
  • FIGURE 5 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 yarn 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 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
