Definitions

  • ABSTRACT A preformed multiturn coupling element of the helicalcoil or meander type is juxtaposed with a tape and a loop is formed by a stitching thread whose needle is thrust upwardly between each pair of turns.
  • a gripper engages the loop and draws it laterally out of the coupling element to reintroduce it between another pair of turns where it is engaged by another loop thrust through the tape.
  • This invention relates to a method of amking-a slide fastener, More particularly, this invention relates to a method of making such a half from a textile tape and a preformed monofilarnentary coupling element,
  • a slide fastener usually comprises a pair of textile support tapes each carrying on one longitudinal edge a coupling element, A slider is displaeeable along these elements to join them together and separate them,
  • a coupling head is formed in the filament between the two shanks of one turn, and the upper shank of each turn is connected by a bight to the lower shank of the upstream turn and the lower shank of each turn is similarly connected to the upper shank of the downstream turn, or vice versa
  • each turn has a bight portion connecting each shank to the shanks of the turns on each side
  • the shanks may lie directly one above the other, seen in a projection orthogonal to the plane of the tape, or may be oppositely inclined as in a true helix,
  • Such coupling elements are secured to the support tape as a general rule by stitching,
  • the stitching usually overlies the two shanks of the fastener, two rows of stitching usually being employed to insure secure fastening,
  • Another object is the provision of an improved method for securing a coupling element to a support ta e,
  • each stich is pulled laterally away from the coil away from the coupling heads thereon and is thereafter returned under'the next turn and released once the next loop is passed therethrough,
  • the coupling element is closed in projection and is provided with a longitudinally throu'ghgoing filler cord, The loops each pass up through the cord, then under the next turn where the next loop passes through it,
  • This method forms a type 203 chainstitch according to Federal Standard No, 751a of Jan.- 1965,
  • the arrangement of FIG 5 has two rows of stitching 2e which cross over each other:
  • FIG. 3 shows a method similar to that of FIG. 1 wherein the coil 3 is provided with a longitudinally throughgoing filler cord 12 through which the needle 8 pierces.
  • the individual loops 7' here go from above the cord 12 to below it, passing under the one lower shank b and under the next so that the filler cord 12 holds the coil 3 down.
  • a slide-fastener made with stringer halves 1, 2, 3, according to this invention has its stitching 2 completely received within the coil so that the slider will not wear through the stitches as it is displaced along the fastener, thereby giving the fastener a much longer service life. Since a preformed coil is used the production speed is greatly increased as the controlling factor becomes the stitching speed of the sewing apparatus.

  • a method of making a slide-fastener stringer half comprising the steps of:
  • steps (c) and (d) for the succeeding turns of said monofilament while advancing same and said tape through said station, a pair of such loops being passed through said tape and said other loop being passed through both of said first loops of said pair.
