Abstract: Provided is a fastener stringer including a row of metal elements having a plating film formed with improved thickness uniformity without waste, even if the elements are not electrically connected to each other in advance. For each of ten adjacent metal elements of the fastener stinger, 0.6?D1/A1?2.0 is satisfied in which A1 represents an average value of thickness of the plating film for the ten metal elements at element center on either one main surface side of the fastener tape, and D1 represents thickness of the plating film for each of the metal elements at the element center on the one main surface side of the fastener tape.

Abstract: A zipper component includes a metal plating film provided on the surface of a component body made of a metal. Further, in the zipper component, at least a part of the component body has been thermally treated before bending and thus the metal plating film has a recrystallized structure wherein at least a part of the metal plating film been recrystallized. Accordingly, since the ductility of the metal plating film can be improved, even when the zipper component is bent, the metal plating film can be deformed to follow the deformation of the component body. Therefore, the occurrence of crevicing or cracking in the metal plating film can be prevented.

Abstract: An object of the present invention is to provide, through plating, a slide fastener which has high decorativeness, and which does not have problems in terms of functionality or product quality such as corrosion resistance. Another object is to provide a method of manufacturing an attachment having constituent members.

Abstract: A nickel-free white copper alloy material, wherein a white coating layer containing no Ni is formed on a base material composed of an alloy represented by the general formula: CuaZnbMnc MdXe, wherein M is at least one element selected from the group consisting of Al and Sn; X is at least one element selected from the group consisting of Si, Ti and Cr; b, c, d and e are 0≦b≦22, 7≦c≦20, 0≦d≦5 and 0≦e≦0.3 in terms of % by weight; and a is the balance, the alloy incidentally including unavoidable elements. The white copper alloy material has excellent strength and hardness equal to those nickel silver, as well as excellent workability, corrosion resistance and whiteness in addition to ductility, and has no fear of allergic reactions because of containing no Ni. In the white copper alloy material, fine adjustment of its white hue is possible according to the demand of customers, and satisfactory mechanical properties can be obtained with the desired hue.

Abstract: In a method and an apparatus for plating a plurality of kinds of works, an unattended route-free vehicle transports the works to a number of processing tanks to immerse the works in the processing tanks. A controller calculates a processing time of the processing tanks and a transporting time needed for the vehicle to transport the works to the processing tanks and renders the vehicle to transport one kind of the works during the immersion-processing of another kind of the works, thereby performing the plating process of a plurality of kinds of works one after another.

Abstract: The present invention provides fastener elements for use in a slide fastener in which, regardless of the quality of material, a metallic coating layer having an excellent adhesiveness and 0.001 to 1.0 .mu.m in thickness is simply and easily formed on the surface of a fastener element member so that the surface thereof gives out the luster of metal. The surface of the metallic coating layer may further be formed at least thereon with a finishing coat layer. In the present invention, there is further provided a slide fastener having a light weight and flexibility in which such a fastener element member as being made synthetic resin having the luster of metal on the surface thereof.

Abstract: A viscous printing paste is imprinted on a reverse surface of a foundation fabric of a surface-type fastener, and then the paste while being viscous is drawn by a suction force to penetrate the foundation fabric from the reverse surface to an obverse surface from which a multiplicity of interlocking elements project. Upon setting of the printing paste, a distinctive mark is produced on the obverse surface of the foundation fabric. With the foregoing processing steps, a large mark can be provided on the surface-type fastener without effecting negative influence on the shape and function of the interlocking elements.
