Abstract

The invention provides a novel and improved method for manufacturing an elongated piece of a composite body composed of a rubber or plastic body of an elongated form and a plurality of electroconductive linear bodies embedded in or bonded on the surface of the elongated rubber or plastic body in alignment, each of the linear bodies extending in the transverse direction of the elongated body in substantial parallelism with each other and being in a curved, bent or corrugated form useful as a connector, electromagnetic shielding gasket and the like. Different from conventional known methods, the invention proposes a method in which the linear bodies are first integrated with the sheet of rubber or plastic followed by corrugating the linear bodies together with the sheet and chopping of the thus corrugated composite body into pieces in a plane perpendicular to the longitudinal direction of the linear bodies.

A method for manufacturing an elongated piece of a composite body composed of a polymeric body of an elongated form and a plurality of linear bodies of an electroconductive material embedded in the elongated body in alignment, each of the linear bodies extending in the transverse direction of the elongated body in substantial parallelism with each other and being in a form, which comprises the steps of

(a) integrally bonding a plurality of straight linear bodies of an electroconductive material on at least one of the surfaces of a polymeric sheet in alignment and substantial parallelism with each other,
(b) plastically deforming the linear bodies in corrugation with a regular pitch together with the plastic sheet,
(c) integrally providing a layer of a rubber overlying the array of the corrugated linear bodies to give an integrated composite body, and
(d) cutting the integrated composite body in a plane perpendicular to the longitudinal direction of the linear bodies about a single pitch of corrugation to provide a composite body having a single pitch of corrugation and two oppositely facing substantially parallel contacting end surfaces.
