Definitions

  • weft yarn is inserted into the warp shed by a pair of cooperating carriers mounted on the ends of flexible tapes that reciprocate into and withdraw from the warp shed.
  • the tapes themselves are generally mounted on tape wheels that are mounted on each side of the loom lay.
  • the tape wheels are driven in an oscillating manner by suitable drive means to cause the tapes to reciprocate into and from the shed.
  • the inserter carrier grips the yarn, which comes from a stationary source, and takes it approximately one half the distance through the warp shed.
  • the carrier on the opposite tape which is often called an extending carrier, pulls the weft yarn the remainder of the distance through the shed.
  • An additional object of this invention is to provide an improved guide raceway in which the inserters and tapes do not contact the warp yarns.
  • FIG. 1 is a fragmentary perspective view showing how the improved guide raceway of this invention is mounted on the loom lay.
  • FIG. 2 is a cross-sectional view taken through the raceway and
  • FIG. 3 is a top elevation of a piece of the improved raceway.
  • the carrier 16 is connected to a tape 17. It is this tape 17 which is fastened to a tape wheel or other drive means for oscillatory movement into and from the shed 15.
  • an elongated body portion 20 for mounting on the loom lay in the manner shown in FIG. 1.
  • the raceway can be secured to the lay by any suitable means such as bonding, rivoting or with any other desired type of fastener.
  • the body portion is shown in FIGS. 2 and 3 as being provided with openings 21 for receiving fasteners to secure body 20 to lay 10. Since the particular type of fastener used is not important, they have been omitted from the drawing.
  • each of the elements making up the first series includes means forming a pair of opposed shoulders that define the lateral limits of the raceway for receiving the tape.
  • these means comprise a pair of upstanding ears 23 that form a pair of opposed shoulders 24 that define the lateral limits of the raceway 25.
  • Located between the opposed shoulders 24 are means defining an individual tape supporting surface adjacent each of the pair of shoulders.
  • the extended portion 26 forms a tape supporting surface adjacent the left hand shoulder 24 while the extension 27 forms a tape supporting surface adjacent the right hand shoulder 24, as viewed in FIG. 3.
  • a second series of elements 35 are provided which also extend upwardly from elongated body 20 and these elements are located at spaced intervals along body 20 and alternate with elements of the first series of elements.
  • the element has only one raised ear 36 and that this ear forms a shoulder 37 that defines the lateral limit of the raceway 25 on one side only.
  • the extension 38 running from shoulder 37 extends completely across the width of the guide raceway the entire distance between the opposed shoulders 24 of the first series of elements 23.
  • the function of the supporting surface provided by extension 38 is to insure that the carrier 16 remains elevated above the lower warp sheet. Without these supporting surfaces, the carrier 16 would fall into the recesses located between supporting surfaces 26 and 27 of elements 22 and damage the warp yarns.
  • the element 35 does not have an ear on the end opposite the ear 36 so that any warp yarns which are crossed can freely slide from the bearing surface into one of the grooves 28.
  • the guide raceway is here shown as being constructed as an integral unit and this method is preferred as a matter of manufacturing convenience. lt is apparent, however, that the upstanding series of elements could as well be provided as separate units which are secured to the base 20. Generally, it is preferred that the raceway be constructed of some suitable low friction material with good impact consistence. For example, a cast urethane is well suited in this particular application.
  • a first series of elements extending upwardly from said elongated body at spaced intervals along the length of said elongated body, said elements including,
  • a second series of elements extending upwardly from said elongated body at spaced intervals alternating with the elements of said first series of elements, the elements of said second series including;
