Heat fromad TPV co-extruded Header trim

Abstract

A method is provided for manufacturing an upper reveal that conforms to a curved portion of a window opening of a motor vehicle door frame. The upper reveal is formed from TPV and a carrier. The method includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; and bending the upper reveal to conform to the curved portion of the window opening of the motor vehicle door frame.

1 . A method of manufacturing an upper reveal conforming to a curved portion of a window opening of a motor vehicle door frame from TPV and a carrier, the method comprising the steps of:
 co-extruding the TPV with the carrier;   curing the TPV to form the upper reveal;   heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; and   bending the upper reveal to conform to the curved portion of the window opening of the door frame.   
     
     
         2 . A method as set forth in  claim 1  including the step of cutting the upper reveal to a predetermined length prior to the step of heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV. 
     
     
         3 . A method as set forth in  claim 2  wherein the co-extruding step includes the step of embedding the carrier within the TPV. 
     
     
         4 . A method as set forth in  claim 3  including the step of roll forming the carrier prior to the step of co-extruding the TPV with the carrier. 
     
     
         5 . A method as set forth in  claim 3  including the step of molding the carrier prior to the step of co-extruding the TPV with the carrier.
