摘要

A process for the manufacture of flexible sealing joints, particularly for doors and hoods of motor vehicles, comprising the steps of forming a fastening strip by extruding a mixture of a mixture of elastomeric or plastomeric material preferably on flat metal reinforcement, optional vulcanization by heat treatment of the resulting assembly and subsequent transverse bending according to the desired profile, of forming a sealing strip by extrusion of a mixture of expandable and vulcanizable elastomeric material and its subsequent expansion and vulcanization by thermal treatment, characterized in that the coupling of said fixing band is carried out in such a way that the longitudinal development of said sealing band is greater than 1 + 20% with respect to the longitudinal development of said fixing band.
