ABSTRACT:
A method of producing curved slide fastener chains or a curved slide fasteners is disclosed. Fastener elements are planted along respective one side edges of a pair of fastener tapes, at least one of which tapes is made of solvent-swelling fibers. The fastener elements planted on the respective tapes are inter-engaged with each other to form a fastener chain. A solvent or its aqueous solution, or a solution containing a solvent and dissolving a soluble adhesive, is applied onto either one of the fastener tapes made of solvent-swelling fibers. Subsequently, the fastener chain is shaped into a desired curved configuration. The shaped fastener chain has its curved configuration fixed by being served on a texture, by solidification of the adhesive dissolved in the solvent after evaporation of the solvent or by applying an adhesive onto the shaped fastener chain and solidifying the adhesive. By mounting a slider, upper stops and lower stops to the fastener chain before or after the above-described shaping, curved slide fasteners can be similarly produced.
