JOINT D'ETANCHEITE ET SON PROCEDE DE FABRICATION

摘要

The seal strip consists of an extruded U-section fixing element (1), having an inner reinforcement (10) with openwork zones, and at least one seal lip (2). The seal is extruded simultaneously with a floating masking element (3) which is attached by one end to the fixing element to conceal any faults in the revealed surface of the seal caused by the openwork zones in the reinforcement. In a variant the masking element can be made separately and attached to the seal by thermal adhesion. The seal is made e.g. from an elastomer or plastomer material.
