Method of manufacturing a profiled strip (section) forming a clip (clamp) having a metal reinforcement sheathed in a plastic, and profiled strip thus obtained

摘要

The invention relates to a method of manufacturing a profiled strip forming a U-shaped clip, having a metal open-work (mesh) reinforcement (1) embedded in a body made of plastic (2), of the type in which the plastic (2) is continuously extruded in the pasty molten state over the reinforcement (1), the plastic constituting the body of the profiled strip is left to harden by cooling and the composite thus produced is formed into a U. According to the invention, in a preliminary phase, at least part of the metal reinforcement (1) is sheathed in a thin layer of an additional plastic, so as to close off the open areas (mesh cells), cut-outs or spaces made in this metal reinforcement and this additional plastic is allowed to solidify before carrying out the extrusion of the plastic (2) constituting the body of the profiled strip.
