Definitions

  • This invention relates to the production of a plied structure and more particularly to the production of a cord formed on a ring twister.
  • Ring twisters are widely used in the production of strands or cords. In this process two or more yarns called singles are pulled from supply packages by feed rolls, passed through a guide and then to a traveler, after which the plied structure is taken up on a rotating bobbin. The speed of the bobbin and other characteristics of the ring twister determine the nature and extent of the twist imparted to the plied structure.
  • a further object of the invention is to provide a method for producing tire cord having superior properties.
  • a still further object of the invention is to provide an improved ring twisting apparatus for the manufacture of cords.
  • Figure 1 is a view in front elevation of a preferred form of an apparatus for practicing the present invention
  • Figure 2 is a view in section taken along the lines 22 in Figure 1;
  • Figure 3 is a perspective view of an improved type thread guide used in practicing the present invention.
  • Figure 4 is a perspective view of a modified type thread guide used in practicing the present invention.
  • Figure 5 is a plan view of a ring twister showing another embodiment of the invention.
  • cord having superior physical characteristics may be formed on a ring twister by carefully controlling the point at which the plying takes place.
  • the point of plying is controlled by inserting a separating element in the thread path between the feed rolls and the traveler of the ring twister. In this way the point of plying is maintained between the element and the traveler and not permitted to back up into contact with the feed rolls.
  • twisted singles 12 and 13 which are to be twisted together to form twisted cord 14 are withdrawn fromsupply packages (not shown),
  • the singles 12 and 13 are withdrawn from their supply packages by means of driven feed rolls 15, 16 and freely rotatable cradle roll 17.
  • the singles Upon emerging from the feed rolls the singles are passed through a guide 18 and then through traveler 19 running on ring 20 and taken up by a rotating bobbin 21 driven by suitable means (not shown).
  • a cylindrical bar 22 there is interposed between the feed rolls and the guide 18 a cylindrical bar 22.
  • the axis of bar 22 is normal to the axis of the feed rolls.
  • the bar 22 may optionally be combined with the thread guide 18 in a unitary structure
  • the singles passing from the feed roll are passed around the opposite sides of the cylindrical bar 22 as shown in Figure 1, thus preventing any possibility of the plied structure 14 being formed adjacent to or in contact with the feed roll assembly.
  • Figure 2 illustrates more clearly the path of thread travel from the supply packages to the ring twister bobbin 21. It will be noted that the singles are passed underneath the first driven feed roll 15, then between feed roll 15 and cradle roll 17 'and from there between driven feed roll 16 and cradle roll 17.
  • the unitary structure comprising the separating guide 22 and pigtail guide 18 is mounted on a horizontal rail 23 running the length of the ring twisting machine by means of threaded portion 24. It will be apparent that the manner of mounting these elements is not a critical part of the invention and they may be affixed to the ring twister apparatus in any appropriate way.
  • Figure 3 shows a perspective view of the unitary structure comprising the separating guide 22 and the pigtail guide 18.
  • a modified form of separating guide is shown in Figure 4.
  • a small wheel 25 is mounted in freely rotatable relation on axle 26.
  • Wheel 25, which may be constructed of plastic or other suitable material, is provided with a grooved portion 27 around its periphery to accommodate the running singles.
  • one single is passed around one side of the wheel 25 and one single around the opposite side. The point of plying then is located below the wheel 25.
  • FIG. 5 Another embodiment of the present invention is shown in Figure 5.
  • the point at which the singles are twisted together to form the plied structure is controlled by means of thread guides interposed between the supply packages and the feed rolls.
  • Singles 28 and 29 are withdrawn from supply packages (not shown) and passed through thread guides 30 and 31, respectively.
  • Guides 30 and 31 are spaced far enough apart so that the singles 28 and 29 will be maintained in spaced relation during their passage through the assembly of feed rolls and cradle roll 1517. It is seen that the point of plying 32 occurs in free space a short distance from the feed roll assembly.
  • the plied structure is then led via guide 33 to the ring twister takeup as usual.
  • the optimum distance between guides 30 and 31 will, of course, depend on the size and the weight of the feed rolls and cradle roll, as well as the type of twist in the singles and the final cord.
  • junction point of singles fell into contact with surface of both feed roll and cradle roll until distance between guides was at least 3 mm.
  • the eifect of varying the diameter of the cylindrical bar 22 shown in Figures 1, 2 and 3 was determined as follows. Singles of 1650 denier viscose high tenacity rayon containing 720 filaments and having 12 T. P. I. 2" twist were withdrawn from supply packages by a feed roll assembly similar to that shown in Figures 1 and 2 and taken up on a ring twister operating to put 12 T. P. I. S twist in the plied cord. After passing through the feed roll assembly the singles were conducted around opposite sides of a separator bar 22 before passing through thread guide 18 as shown in Figure 1. A number of samples were run withthe same singles, using bars 22 with varying diameters. The effect on cord strength may be seen in Table II. This data indicates that the size of the separator bar is not critical.
  • An apparatus for producing a cord from two single threads comprising an assembly of iced rolls for feeding the singles at a uniform rate of speed in side by side relation, a ring twister spindle including a bobbin for twisting the singles together and for collecting the twisted cord and a unitary elongated cylindrical bar separator and pigtail-type guide disposed in the path of thread travel between said assembly of feed rolls and said ring twister spindle, said guide being mounted integral with and disposed beneath said separator, said separator being disposed in a substantially horizontal plane with the longitudinal axis thereof extending normal to the direction of travel of the cord through the pigtail-type guide.
