Definitions

  • a group of threads comprising one thread of each kind and color occurring in the desired pattern is continuously wound onto a rotating body having a small winding diameter on which the said group of threads is wound and having a large winding diameter to which, at every turn or fixed number of turns, a single thread, each time selected from the group of threads in the sequence conforming to the desired pattern, is transferred.
  • the invention relates to a method and a device for assembling according to a random pattern warps for the manufacture of fabrics from two or more yarns differing from each other, in particular the comparatively short warps for the manufacture of fabric specimens.
  • lt is the object of the invention to provide a method that enables an economical assembling of short warps for multicolored specimens and that moreover is suitable to be performed by automatically working apparatuses.
  • the method according to the invention is characterized in that of each of the yarns occurring in the desired pattern at least one thread is continuously wound on to a rotating winding body with at least two coaxial winding surfaces, the one of which has a large and the other, in comparison, a considerably smaller circumference, and that the threads are wound alternately, according to the sequence in which the various yarns occur in the desired pattern on to a winding surface with the large circumference, whereas the remaining threads are wound on to a winding surface with the small circumference.
  • the thread windings laid onto the large winding surface are cut through after completion of the winding and transferred on to a warp beam.
  • the thread-windings laid onto the small winding surface must be considered waste.
  • the total length of them need not, however, amount to more than a low percentage of the total length of the warp threads obtained and is of little importance as compared with the saving oflabor.
  • the apparatus according to the invention is characterized in that the winding body is provided with at least two coaxial winding surfaces, one of them having a considerably smaller circumference than the other, and that the threadfeeding device is provided with two or more thread guides, each of them being displaceable as regards the winding body in such a way that a thread fed onto the winding body by a thread guide is wound on by the one or the other winding surface, depending on depending on the position of the thread guide.
  • the displacements of the thread guides required for obtaining the desired warp design can be brought about entirely automatically by coupling the thread guides to-a control device known in the art, that e.g. can be programmed with the aid of a control panel on which counters have to be adjusted according to the desired design, or with the aid of punched cards, punched tapes, magnetic tapes or other like means.
  • the apparatus according to the invention can be realized in various ways.
  • One of the possible embodiments is characterized in that the small winding surface is situated within the large winding surface and in that each of the thread guides is provided to the end of an arm stretching approximately in the axial direction of the winding body, which arm is movable from a position in which the thread guide is outside the small winding surface and inside the large winding surface into a position in which the thread guide is outside the large winding surface, and vice versa.
  • this apparatus is further characterized in that the large winding surface is formed by a number of spokes projecting freely and approximately axially and in that the arms to which the thread guides are connected are displaceable radially, from the position situated within this winding surface to that outside this winding surface and vice versa.
  • the arms which carry the thread guides can shift immediately from the one position to the other by moving radially between the spokes of this reel over a slight distance.
  • the apparatus according to the invention is characterized in that a large and a small winding surface are provided on the winding body next to each other and that each of the thread guides can be displaced individually from a position radially opposite to the small winding surface to a position radially opposite to the large winding surface, and vice versa.
  • This construction of the apparatus is particularly suitable to be applied in a sectional apparatus.
  • such an apparatus according to the invention is further characterized in that it consists of a number of sections that each comprise a large and a small winding surface situated next to it and at least two thread guides, and in that the displacement of every thread guide from the one position to the other is coupled with the displacement of one thread guide of every other section.
  • the invention is further elucidated below by means of two embodiments schematically shown in the drawing.
  • FIG. 1 shows:
  • FIG. 8-11 a schematic view of the second embodiment in the successive stages of winding process
  • FIG. 12 a variant of the embodiment according to FlGS. 8- 1 1.
  • reel 2 open at one side, the freely stretching arms 310 of which form the winding surface.
  • arms 11 and 12 each are connected with a pneumatic cylinder 14.
  • two threads 15 and 16 of which each has one of the desired colors are guided through thread guide eye 13 of arms 11, respectively 12 and attached to shaft 1 of reel 2.
  • arm 12 is moved back in its rest position inside reel 2, after spoke 10 has been passed.
  • arm 11 is moved to position 11' with thread 15, which during the above cycle was wound onto the shaft 1 (see FIG. 5.), now causing thread to be taken along by spoke 3 and to be wound on to the reel (see FlG. 6).
  • arm 11 will remain in position 11' until spoke 4 has passed. On passing of spoke 5 arm 11 is brought inside reel 2 and next moved back to position 11'.
  • the thread windings that are laid on to shaft 1 on winding of reel 2 can be considered waste, but because the circum ference of shaft 1 is much smaller than that of reel 2, this loss of yarn is of no significance.
  • the apparatus in principle comprises a shaft 21 rotatably supported in its bearings with mounted onto it a number of discs, of which, for the sake of simplicity, the drawing only shows the two discs 22 and 23, and a number of sliding rods, of which in FlGS. 8, 10 and 11 only the sliding rods 24 and 25 have been indicated, which sliding rods 24, respectively 25 have been furnished with thread guide eyes 26, respectively 27 provided near disc 22 and thread guide eyes 28, respectively 29 provided near disc 23. Threads 30, 31, 32 and 33, respectively, which are attached to shaft 21, are fed through thread guide eyes 26, 27, 28 and 29 respectively. At the edge of their winding surface discs 22 and 23 are provided with projections 34 and 35.
  • Disc 22 is also provided with two arms 36 and 37, slantingly projecting from the cylindrical winding surface, which arms are provided on shafts 38, respectively 39 pivotably and approximately radially supported in their bearings in disc 22.
  • disc 23 is provided with projecting arms 40 and 41, which are provided on shafts 42, respectively 43. Arms 36, 37, 40 and 41 simultaneously can make a swinging movement of about causing them to come from the position shown in FIG. 8 into the position shown in FIG. 20. For this position shown in FIG. 8 into the causing them to come from the position shown in FlG. 8 into the position shown in FIG. 10.
  • the common control rod 44 is provided in the hollow shaft 21.
  • sliding rod 24 should be moved to the left, so that guide eye is taken along by projection 34 and wound on to disc 22 (see FlG. 8).
  • sliding rod 24 is moved to the right until guide eyes 26 and 28 are again opposite to the sections of shaft 21 situated by the side of discs 22 and 23 and guide eyes 27 and 29 are placed opposite to discs 22 and 23 by moving sliding rod 25. Then thread 31 is taken along by projection 34 and wound on to disc 22 (see FIG. 11).
  • threads 32 and 33 are similarly wound on to disc 23 in the same order as threads 30 and 31 and here also a lease is laid between shafts 42 and 43 by arms 40 and 41.
  • a part of the warp with the design is formed on each of discs 22 and 23 . Because threads 32 and 33 need not be identical to threads 30 and 31, the design of the two warp parts may have a different color combination.
  • the number of discs on shaft 21 and the number of guide eyes on each of the sliding rods corresponding with them, as well as the number of sliding rods, may be chosen entirely according to the need, causing the apparatus to have a considerable great range of application.
  • FIG. 12 shows, consist of rods 46, freely projecting in axial direction to one side, and situated above winding surface 45.
  • guide eye 47 is connected with sliding rod 49 via a rod 48 bent at right angles and the moving mechanism of these sliding rods has been arranged to perform besides movements in axial direction, also to perform movements in radial direction.
  • the radial moving facility of guide eye 47 enables the thread to be laid on the winding surface or, according to choice, across one or more of separators 46.
  • a method for assembling according to a random pattern warps for the manufacture of fabrics from two or more yarns differing from each other, in particular the comparatively short warps for the manufacture of fabric specimens wherein of each of the yarns occurring in the desired pattern at least one thread is continuously wound onto a rotating winding body with at least two coaxial winding surfaces, the one of which has a large and the other, in comparison, a considerably smaller circumference, and the threads are wound alternately according to the sequence in which the various yarns occur in the desired pattern, onto a winding surface with the large circumference, whereas the remaining threads are wound onto a winding surface with the small circumference.
