International Classification:

B60J 10/02
B23P 25/00

US Classification:

277650, 295271

Abstract:

A weather strip seal is provided for sealing between first and second structures, and a method for manufacturing such a strip seal. The weather strip seal includes a main leg made of a polymeric material, having one side and another side and terminating in first and second ends, a first sealing portion designed to press against the first structure and extending on the one side of the leg adjacent the first end, and a metal carrier for retaining the shape of the strip seal which has an asymmetrical substantially U-shaped cross-section having a first branch reinforcing a portion of the main leg and a second branch extending from the second end on the another side and terminating in a second sealing portion designed to sealingly press against the second structure. An ionomer tie layer is located between the metal surface and the at least one polymeric material.

Abstract:

A process for creating a seal having a first linear portion and a second curved portion joined thereto is provided. The process includes providing a retaining section including a threaded metal wire with warp fiber disposed therein, forming the carrier section into a predetermined cross-sectional shape using forming rolls, extruding a polymeric material around the carrier section and generating a contacting member onto said carrier section to form a seal, heating the seal within an oven to cure the polymeric material and to break down the warp fiber so that the seal is readily bendable, and heating then cooling the second portion of the seal in a forming device for predetermined times at predetermined temperatures to cause the second portion of the seal to be formed in a curved manner.
