Abstract

A method for producing a flat elastomer seal (1) having a carrier sheet (2) which is covered by highly vulcanized elastomer material (3) on at least one side, according to the invention, comprises the following steps:- providing at least one flat material sandwich (7) formed by a carrier sheet (2) and at least one slightly vulcanized elastomer layer (8; 8a, 8b) attached to at least one side of the carrier sheet (2), in particular two slightly vulcanized elastomer layers (8a, 8b) each attached to one of the two sides of the carrier sheet (2); and- compression molding of the material sandwich (7) in a mold (9) which has a mold cavity (10) corresponding to the shape of the seal (1) to be produced, by applying heat (T) and pressure (p) to the at least one slightly vulcanized elastomer layer (8a, 8b) to allow the elastomer material to flow and fill the mold cavity (10) and to increase the vulcanization of the elastomer material to a higher degree in order to obtain a highly vulcanized elastomer material (3).
