Retaining box for slide fastener

A slide fastener tape is provided. The slide fastener tape extends in a longitudinal direction. The slide fastener includes a weave structure formed with warp threads arranged in the longitudinal direction, and weft threads arranged along a transversal direction perpendicular to the longitudinal direction. The slide fastener tape includes a cord arranged along one side edge portion of the fastener tape. The weft threads are made from filament yarns and the warp threads comprise a plurality of threads made from spun yarn.

Slide fastener tape

There is provided a stop for a slide fastener. A top plate and a bottom plate are linked with one another at a transversely intermediate position by an integral connecting post. The lower side of the top plate is substantially flat. The bottom plate slopes away from the connecting post to form two leg members provided with a respective end flange pointing towards the top plate, the leg members being adapted to cooperate in use with the top plate to retain fastener tapes therebetween.

Stop for a slide fastener, and a method for the manufacture thereof

Provided are a metal double-sided tooth that prevents a flow protruding portion from protruding from the boundary between a coupling concave portion and a body, and a slide fastener using the metal double-sided tooth. The inner side of a coupling concave portion is formed in a substantially bowl shape and a concave portion is formed throughout the boundary between the coupling concave portion and a body and a front side and a rear side of the body. Further, when the metal double-sided tooth is attached to a fastener tape, it is possible to prevent a flow protruding portion generated by caulking a pair of legs from protruding outward from the coupling concave portion or the front side and the rear side of the body until sliding friction is generated in a slider.

An aluminum alloy with excellent decorativeness, having a composition represented by the general formula AlMgMnCr, wherein b, c, and d are, in mass percentage, 3.0&#x2266;b&#x2266;5.6, 0.05&#x2266;c&#x2266;1.0, 0.05&#x2266;d&#x2266;0.7, c+d&#x3e;0.2, and a is the balance with unavoidable impurity elements possibly being contained, wherein a matrix of the aluminum alloy is a structure substantially composed of an aluminum solid solution, in which no &#x3b2;-phase is present. This alloy has excellent decorativeness and decorativeness as well as superior strength, hardness and other such mechanical properties and is useful as materials for slide fastener constituent members, such as their elements, stops, and sliders, and/or in snap buttons, ordinary buttons, and clasps.

Aluminum alloy with excellent decorativeness

In a upper stopper device for a slide fastener having a cross section of a substantially U shape, which is adapted to be attached continuously to a fastener element row of a stringer capable of being engaged with or separated from each other, an end portion of the upper stopper device opposite to the fastener element row is formed with a widened portion, which abuts against wing plates at a shoulder opening of a slider into which the stringer is inserted so that the slider can stop. Further, a caulking portion is formed in a range between the widened portion and at an end portion side toward the fastener element row. The slider abuts against the widened portion of the upper stopper device attached to the stringer so that it reliably stops.
