  • Patent number: 10687591
    Abstract: A monofilament having, in cross section, a first width and a second width being orthogonal to the first width and being greater than the first width is helically wound about the circumference surface of the mandrel. Each helical unit included in the configured helix of the monofilament includes a pair of legs, a first coupling portion coupled between said pair of legs, and a second coupling portion coupled between one leg of said pair of legs and the other leg of a pair of legs in an adjacent helical unit. The second width of said first coupling portion is oriented along the axial direction of the mandrel. The first coupling portion in each helical unit in the helix is pressed such that the second width of the first coupling portion is widened in its width direction, thereby forming an engagement head.

    Abstract: Slide fastener elements made of a helically wound synthetic resin monofilament and the method of forming the same. According to a preferred embodiment, each fastener element comprises an interengaging head arranged on one-line in the longitudinal direction of the slide fastener elements, a pair of interengaging head-side widened portions formed at the both sides of the interengaging head, upper and lower legs extending from the both ends of the interengaging head through the pair of interengaging head-side widened portions respectively so as to transverse the longitudinal direction of the slide fastener elements and a turn extending between an upper leg of one slide fastener element and a lower leg of an adjacent slide fastener element through a pair of connecting portions formed at the both sides of the turn. The interengaging head is formed by pressing the monofilament to be sidened at its portion corresponding to the interengaging head.

  • Patent number: 5031283
    Abstract: A helical coil seam construction for joining the ends of a length of papermakers fabric into a continuous loop is disclosed using a pair of generaly helical coils formed of a multifilament yarn subjected to a stiffening treatment with that stiffened yarn being formed into a helical coil. A first such coil is affixed to a first end of a length of papermakers fabric and a second coil, wound in the direction opposite to the winding of the first coil, is affixed to a second end of the fabric, opposed to the first end. Means are provided for releasably joining the coils with the loops thereof in an interengaged relationship, whereby the ends of the fabric are releasably joined to form a continuous loop of the fabric.

  • Patent number: 4989300
    Abstract: A coupling element for slide fastener is formed from a monofilamentary material such as polyester, nylon and like thermoplastic resins into a continuous meandering or zig-zag structure having a substantially semi-circular transverse cross-section, the coupling element having a coupling head, an upper leg and a lower leg extending oppositely from said head in parallel spaced apart relation and a heel interconnecting each of the upper and lower legs. The heel is oriented by rotation through 90.degree. or 180.degree. and protrudes at least in part beyond the outer surface of the leg thereby providing increased surface area of the heel for sliding contact with a slider.

  • Patent number: 4827579
    Abstract: A jointing device for connecting together the ends of a papermakers or like fabric including coil elements (13, 14) attachable to the respective fabric ends, the end regions (20, 21) of the individual turns of the coils being so profiled as inherently to maintain, on interdigitation of the coil, a degree of interengagement which is sufficient to provide and maintain a tunnel (16) to receive a pintle wire (15) into engagement therewith. It is suggested that the coils be such as to be capable of interdigitation by a mechanical device such as, for example, a slider (22).

  • Patent number: 4604774
    Abstract: A sliding clasp fastener comprising a pair of support tapes carrying rows of coupling elements thereon and a slider adapted to couple and uncouple the rows of elements. The elements are formed from a plastic monofilament into a continuous spiral or meander formation. The monofilament is provided with a multiplicity of indents arranged to extend longitudinally thereof, the indents being filled with a lubricative agent.

  • Patent number: 4451957
    Abstract: A slide apparatus for joining ends of a belt of the type having a plurality of transverse interlocked spiral elements. The slide apparatus includes two tapered overlapping channels for the reception of the overlapping belt ends so that upon movement of the slide apparatus the overlap of the belt ends will be reduced. The tapered channels terminate in a common narrow channel having a width equal to the overlapped end spiral elements so that upon passage of the two belt ends from the narrow channel a spring biased pusher element will force the overlapped spiral elements into meshing engagement, wherein a pintle wire, inserted into the passage defined by the intermeshed spiral elements, connects the belt ends.
