  • Patent number: 4718150
    Abstract: In a stringer for a slide fastener wherein coupling elements are molded on longitudinal supporting means, such as an edge of a tape or spaced connecting threads, leg portions of the coupling elements are formed with recesses to define rapidly cooled portions which are molded to the supporting means. The rapidly cooled portions eliminate porosity to produce greater adherence and strength of the polymer bonding the coupling elements to the supporting means as well as reducing cost.

  • Patent number: 4470794
    Abstract: An apparatus for folding and forming a continuous train of slide fastener coupling element bodies into a train of coupling elements includes a rotating forming disc against which the coupling element bodies are fed. The train is held on the forming disc for a portion of the disc rotation by a pair of flexible discs which clamp the leg portions of the bodies against the sides of the forming disc. After rotation through a portion of the forming disc circumference, the flexible discs are cammed outwardly and the train of coupling elements is pulled from the discs.

  • Patent number: 4353760
    Abstract: A method for forming slide fasteners with attached sewing guides is disclosed wherein a stock strip of paper is coated with adhesive and release material and subsequently formed into pairs of member sections which are folded and then assembled on center sections to form composite sections. Perforated sewing lines and/or window openings are punched in the composite sections and the composite sections are attached by at least two of the strips of the pressure sensitive adhesive to the tapes of slide fasteners to form slide fasteners with attached sewing guides.

  • Patent number: 4349943
    Abstract: A coupling element for a slide fastener has a grooved head adapted to receive tongues of opposed elements to prevent lateral shifting of the elements. The tongues, as well as tapes embedded in the elements, are upwardly offset from the center of the elements so that the top edges of the tapes, the tongues and the grooves are coplanar. Flat abutment surfaces at the rear of the head absorb transverse loads and stabilize the fastener.
