Dewatering screen for manufacturing paper with watermark papierversteifenden

The invention relates to a dewatering screen (40) for the production of paper (10) having a papierversteifenden watermarks (12, 14), according to the invention provided in the that the papierversteifende watermarks (12, 14) in the form of at least one region of increased paper thickness (20 , 24) is defined, inside which a in transmitted light bright appearing watermark-fine structure (22, 26) is in the form of patterns, characters or a code. The dewatering screen (40) comprises a support wire (42) having a screening surface (52) which is deposited on the paper, as well as arranged in a a portion of the carrier screen (42) perforated plastic watermark insert (60). The plastic watermark insert (60) has to generate the papierversteifenden watermark (12) has at least one below the sieve surface (52) lying lowered portion (62), in the interior of the depressed area (62) outstanding motive members (66) having a characteristic dimension of 0.6 mm or less are arranged in the form of patterns, characters or a code, which serve to generate the watermark-fine structure (22).
