Abstract

Abstract This disclosure provides a means for retarding or masking discoloration of polyvinyl chloride frame or flange for the windshield or other exposed external parts of a vehicle. The invention comprises a new constructive arrangement of a flange for windshields and guards of vehicles that consists in establishing an initial formation of a layer through extrusion of a flange in polyvinyl chloride, in a color that does not show the migration of rubber, this layer receiving on its outside surface a layer of P.V.D.F. (polyvinylidene fluoride), also known as Kynar™, so that this layer has no direct contact with rubber, by reason of an extension of its side edges inside the extruded flange of polyvinyl chloride, which thereby forms a lateral covering of protection.
