Definitions

  • FIG. 1 is an enlarged diagrammatic perspective illustration in section of a traveler and ring according to the invention
  • FIG. 2 is a top view of the traveler according to the invention.
  • FIG. 3 is a side view of the traveler according to the invention.
  • the numeral 10 generally denotes the twisting ring 12 and the novel generally elliptical traveler 14 carried thereby.
  • the ring 12 includes the usual upstanding annular web 16 and an upper horizontal flange having inwardly extending bearing portions 18, 20, respectively, of arcuate cross section.
  • the novel traveler 14 of the invention includes a pair of opposed inturned arcuate leg members 22, the inner portions of which serve as bearing surfaces to slidingly engage the bearing portions of said twisting ring.
  • These bearing surfaces of the traveler may be rounded slightly as illustrated at 24 in FIG. 2, however, this surface should be maintained as nearly fiat as possible in order to insure a large contact area with the ring thus providing for a longer traveler life and better heat dissipation.
  • a top connecting portion 26 which connects the leg members is provided with a yarn receiving recess 28 on each side thereof at a point closely located to the respective leg member 22. Each of these recesses are identical and therefore only one will be explained in detail.
  • recess may be arranged to accommodate either S or Z twist yarn, with the traveler illustrated beingutilized for S twist yarn.
  • the location of the recess 28 with respect to the inner bearing surface of the adjacent leg member is critical. Its location may be varied slightly to take into consideration ring size, traveler weight and/or intended use, however, I
  • the maximum distance C (FIG. 1) of the recess from the inner bearing surface of the leg portion should not substantially exceed one half of the vertical thickness D of the twisting ring associated therewith. In most instances, the optimum distance C will be less than the maximum defined above. If the location of the recess is extended beyond this maximum distance, the traveler becomes unstable and will not operate in an acceptable manner.
  • edges of the recess may be inclined at an angle for yarn cleaning purposes, if so desired.
  • the side 30 of the recess is angled slightly toward the leg member 22 in order to assist in retaining the yarn therein. This is important in the processing of synthetics in that it assists in holding the yarn in its predetermined position thereby obviating the possibility of the yarn contacting the heated bearing surfaces and becoming fused.
  • the extent A of the recess 28 into the top connecting portion is also important in that it determines the amount of leverage exerted by the yarn on the traveler, i.e., as the depth of the recess should be restricted only by the properties of the material employed in the traveler, therefore, the distance A in FIG. 1 is preferably greater than remaining portion B of the top connecting portion although in some instances, these distances may be equal.
  • twisting ring having an upstanding annular web with an upper flange having radially inwardly and outwardly extending portions of arcuate cross section of a generally elliptical traveler including a top connecting portion and an axially extended opposed arcuate running surface positioned inwardly adjacent the horns of said traveler at each end of said top connecting portion,
  • said top connecting portion of said traveler being provided with a recess along at least one edge thereof positioned from the innermost of said running surfaces a distance up to but not substantially exceeding one half the vertical thickness of said upper flange whereby said yarn is engaged in said recess during winding thereof.
  • said traveler including a top connecting portion having an inwardly curved leg portion at either end thereof forming a pair of opposed arcuate running surfaces for engagement with said flange,
  • said top connecting portion being provided with a recess along at least one edge thereof closely adjacent one of said leg portions, said recess extending from said edge to a point beyond the center of said top connecting portion whereby the leverage exerted on said traveler by a yarn engaged in said recess is substantially reduced.
  • a twisting ring having an upstanding annular web with an upper flange having radially inwardly and outwardly extending portions of arcuate cross section of a symmetrical generally elliptical traveler including a top connection portion and an axially extending opposed arcuate running surface positioned inwardly adjacent the horn of said traveler at each end of said top connecting portion, each side of said top connecting portion of said traveler being provided with a yarn receiving recess, one of said recesses being positioned adjacent the innermost of said running surfaces and the other of said recesses being positioned adjacent the outermost of said running surfaces a distance up to but not substantially exceeding one half the vertical thickness of said upper flange,
  • said recesses extending at least one half the width of said top connecting portion whereby the leverage exerted by said yarn on said traveler during winding is substantially reduced.
