Patent

CA 2527223

A process for the production of a glass run channel (68) is provided wherein the glass run channel has a S-shaped core (12) of a polymeric material, onto which glass and/or frame sealing components are co-extruded. Preferably, a slip agent coating (25) is applied shortly after the sealing components (18, 24, 26) are added so that a completely polymeric glass run channel (68) is produced in a single operation. The polymeric glass run channel (68) is lighter, less expensive and more easily recycled than the prior art glass run channels.

L'invention concerne un procédé de production d'un rail de glissière de guidage de glace (68) comprenant un noyau en forme de S (12) constitué d'un matériau polymérique, sur lequel des éléments d'étanchéité pour la glace et/ou le cadre sont coextrudés. De préférence, un revêtement d'agent glissant (25) est appliqué peu après la mise en place des éléments d'étanchéité (18, 24, 26), si bien qu'un rail de glissière de guidage de glace (68) entièrement polymérique est réalisé en une seule opération. Le rail de glissière de guidage de glace (68) est ainsi plus léger, moins cher, et se recycle plus facilement que les rails de glissière de guidage de glace de la technique antérieure.
