  • Needles are normally formed in pairs although they may be formed singly.
  • 21 piece of wire having a diameter corresponding to the intended diameter of the shanks of the needles is provided. Except for those portions of the piece of wire which become the shanks of the needles, the wire is cut down or swaged down to the blade size, then the customary thread grooves are formed in the needle blades, after which the needles are finished by the forming of the eyes therein and the simultaneous forming of points which are disposed in opposed relation.
  • the cutting down or swaging down of the wire from the diameter of the shank to the blade diameter is a time consuming and, therefore, expensive operation.
  • the primary object of this invention to provide a needle which includes the conventional grooved lade formed in needles of the type to which this invention relates, and wherein the shank is separately formed and suitably secured to the blade whereby the need for the cutting or swaging down of the wire in the initial blade forming operation is eliminated.
  • Another object of this invention is to provide a novel method of economically forming needles for sewing machines and like machines, the method including the steps of providing a wire of a constant cross section and havin a continuous longitudinally extending groove therein, cutting off .a length of the Wire and work forming the length of wire to form at least one needle blade having a point at one end and an eye therethrough adjacent the point and aligned with the groove, and securing an enlarged shank on the blade and remote from the point.
  • Another object of this invention is to provide a novel needle for use in sewing machines and like machines, the method including the steps of forming a needle blade from a continuous wire having a longitudinal groove therein, and then securing a shank to the needle blade.
  • a further object of this invention is to provide a needle particularly adapted for use in sewing machines and like mechanisms, the needle including a needle blade and an enlarged shank, the shank being butt bonded to the needle blade.
  • Another object of this invention is to provide a novel needle which includes a blade and a shank formed of different materials.

  • the wire 18 is cut to a predetermined length by means of a suitable cutter 26 in any known manner.
  • the length of the removed portion of the wire will vary depending upon the particular needle and whether or not two needle blades are simultaneously formed.
  • This invention is not restricted to the forming of a single or double needle blades.
  • FIGURE 2 A typical needle blade 11, prior to the application of the shank thereto, is shown in FIGURE 2.
  • the needle blade I]. is positioned within a suitable mold, schematically illustrated in FIGURE 3 and generally referred to by the numeral 21, in the position shown in FIGURE 3.
  • Plastic material is delivered to the mold 21 through an injection nozzle 22 so as to fill a cavity 23 of the mold 2?. around the end of the blade 11 remote from the point 12 thereof.
  • shanks may be simultaneously applied to a plurality of needle blades in a single multiple cavity mold.
  • the needle blades Ill may be in back-to-back relation so that a single spline or sprue of plastic material may interconnect a large number of needles for ease of handling.
  • shank 13 could equally as well be formed of metal.
  • the metal could be cast or could be in the form of metal powders which are compacted or sintered or otherwise bonded together and to the needle blade 11.
  • the plastic material of the shank 13 need not be molded around the needle blade 11, but may be provided in the form of a length of tube 24.
  • the tube 24 is cut to a predetermined length by means of a cutter 25 and the length of the tubing 26 cut from the tube 24 is then telescoped over the needle blade 11 in the manner shown in FIGURE 7.
  • the connection between the tubing 26 and the needle blade 11 may be a bonded one, or a sufficiently tight fit to assure the securemcnt of the newly applied length of tubing 26 to function as the shank for the needle blade 11.
