  • FIGURE 4 is a plan view showing the construction of the hooked end of the guide finger illustrated in the preceding view.
  • the improved tmverse device 1 embodying the invention is shown in its operative position interposed between two-stage yarn drawing equipment and a take-up device.
  • the yarn 2 is spun from a spinneret 3, moves through a convergence guide, and is thereafter wound around two sets of draw rolls 4 and separator rolls 5 before being delivered to traverse device 1 and a bobbin 6 of the take-up device.
  • the yarn is drawn by operating draw rolls 4- at different peripheral rates of speed and at different speeds than the rate of extrusion of the filaments from ⁇ spinneret 3.
  • Bobbin 6 is surface driven by a drum 7 rotated by power means 8 operatively connected to drum 7 by conventional drive means 9.
  • Traverse device 1 comprises a framework having a pair of generally upright spaced beam members, lb and lit. Beams 1t) and 11 are positioned in side-by-side relation and are inclined so that they converge at their upper ends and diverge at their lower ends.
  • each beam, M and 11 there is a pulley 12 mounted within a respective bracket 13 secured to beams 10 and 11..
  • the complementary pair of pulleys 12 located at the upper converging ends of the beams are spaced closer to each other than are the pair of complementary pulleys at the lower diverging ends of the beams.
  • Each pulley 12 on a respective beam is positioned so that a vertical plane, extending perpendicularly to the axis of one of the pulleys and passing centrally through its face, also passes centrally through the face of the other pulley it; on the corresponding beam to permit proper mounting and alignment of a belt on corresponding pulleys 12.
  • Shafts 14 extend inwardly of the belts and are interconnected by a universal or flexible joint 15 of common construction.
  • One of the shafts 14 is operatively connected to a motor 16 by means of a belt 17.
  • Endless straps or belts 18 are laced about a corresponding pair of pulleys on each beam, it ⁇ and it.
  • Belts 18 are positioned in spaced side-by-side relation and in a generally upright position with the upper ends of the belts converging and the lower ends diverging, as in the case of beams 1i) and 11.
  • Each of the belts 18 has a plurality of spaced guide fingers 19 mounted on the outer periphery thereof and fastened thereto by suitable fastening means, rivets or the like.
  • the guide fingers 1 9 on one of the belts 18 are positioned in staggered relation to the guide fingers 159 on the opposite belt 118.
  • Each of the guide fingers 19 projects into the space between the belts and each has an upturned or hooked free end 2b which normally engages the yarn.
  • a fixed pigtail guide 21 is secured at one end of an arm 22 fastened at its opposite end to one of the beams.
  • Pigtail guide 21 is positioned above and between the upper ends of beams 1b and 11.
  • Pulleys 12, at the bottom or diverging ends of the beams, are spaced so that bobbin 6 may be positioned closely below and between the pulleys.
  • the bobbin 6 is shown in FIG. 1 positioned below and between the belts l8 primarily to permit illustration of the various components of the improved traverse device 1. lthough the device 1 is operable as shown in FIG. 1, the desired and preferred arrangement of bobbin 6 in relation to the belts 13 and guide fingers l9 thereon is shown in FIG. 2.
  • bobbin 6 is positioned between and forward of the belts 13 at the diverging ends thereof.
  • the belts 18 are mounted on the pulleys 12 in a generally upright position so that the front sides of the belts 18, shown nearest to bobbin 6 in FlG. 2, are traveling in a downward course and tangentially to the peripheral surface of the yarn being wound on bobbin 6.
  • the point at which each guide finger 19 begins to change direction of its downward travel is within a horizontal plane 23 extending through the axis of bobbin 6.
  • the yarn extends from the draw and separator rolls 4 and 5, respectively, to the pigtail guide 21.
  • the yarn is forwarded to the nearest guide finger 19 on the front side of the belts 118, as viewed in the drawing, and is positioned within the hooked end 2'9 of the guide finger.
  • the yarn is then laced in Zig-Zag pattern, alternately, from the uppermost guide finger 19 on one of the belts downwardly to the next succeeding guide finger 19 on the opposite belt, and so forth down to the lowermost guide finger 19 on the belts 13, the yarn being positioned in each case in the hooked ends of each guide finger.
  • the angle of the yarn extending from one guide finger 19 on one belt to the other guide finger 19 on the opposite belt increases progressively as does the lateral displacement of the yarn while it moves downwardly from the upper to the lower end of the traverse device. From the lowermost guide finger 19 the yarn is wound onto bobbin 6.
  • the guide fingers 19 cooperate therebetween to establish a. zigzag or tortuous course of travel of the yarn with a progressively widening lateral displacement as the yarn moves to bobbin 6.
  • each guide finger E9 on a respective belt reaches its lowest point of its straight-lute downward travel (the point of tangency in FIG. 2), the corresponding belt on which it is mounted revolves around pulley 12 and carries the guide finger away from the path of the yarn.
  • the point at which the guide finger is disengaged from the yarn defines the end of a stroke of the yarn traversed across the bobbin.
  • the next succeeding or second guide finger on the opposite belt serves to apply a tension on the yarn and to guide the yarn uniformly across the face of bobbin while traveling to its lowest position on its belt.
  • the yarn When the second guide finger is disengaged from the yarn, the yarn is traversed in the opposite direction in the same manner by the next succeeding or third guide finger on the opposite belt traveling in a downward direction. Thus, the yarn is rapidly traversed back and forth across bobbin 6 whereby a uniformly wound package is formed thereon.
  • FIG. 3 shows one form of construction of the hooked end portion of each guide finger 1%.
  • the surfaces are smooth to permit the yarn to slide off the guide fingers when they begin to disengage from the yarn.
  • the hooked end 2% ⁇ on each guide finger is bent so as to form an acute angle in relation to the body of the guide finger.
  • the guide fingers 1% may be spaced equally apart on each belt with each guide finger on one belt being centrally positioned between a pair of guide fingers 19 on the other belt.
  • the guide fingers on the belts may be repositioned to slightly vary the distance between successive guide fingers.
  • the traverse strokes are off-set, and the yarn is not wound on the bobbin in the same repetitive stroke.
  • Ribboning results in yarn packages being non-uniformly wound and is therefore an undesirable feature that is disadvantageous in further yarn processing.
  • the improved traverse device provides uniform displacement of the yarn in opposite directions with an instantaneous reversal of the yarn at the end of each stroke.
  • the entire operation is smooth, unstressed, and uninterrupted.
  • device ll permits high speed operation and produces uniformly wound yarn packages devoid of so-called bulges which form in a package which 18 not uniformly wound.
