  • Patent number: 4541470
    Abstract: A method of manufacturing sewing machine needles from a cylindrical length of wire by compression molding, comprising the steps of selecting the length of the wire substantially corresponding to two of the needles to be manufactured and a diameter of the wire corresponding to the thickness of a butt of the needles to be manufactured, the length being equal substantially to two coaxial connected needle blanks of one-piece for the needles to be manufactured, simultaneously working the two needle blanks to form the two needles, with the two needle blanks being worked such that the butts respectively face each other, by the steps of forming the blanks approximately to a final cross-sectional dimension of the two needles to be manufactured over their shanks and sections between the butts and shanks while leaving the butts of the two needles facing each other back to back and pressing grooves in the wire from transversely convexly curved outer surfaces of the wire within a region of the shanks, while simultaneously

  • Patent number: 4117930
    Abstract: A packing receptacle for sewing machine needles, with an upper part constructed in the form of a flat cap, in its opening which is provided on one side, a stay-shaped lower part is positively clampingly inserted, the lower part carrying the needles, the latter being inserted in row-form adjacent one another, such that a partial surface of the stay-shaped lower part is exposed as a consequence of gripping recesses provided in the cap-shaped upper part. One of the side walls of the cap-shaped upper part projects over the opening-sided edge of the other side wall surface. The latter side wall has a slot, which slot connects to the gripping recess.
