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