(EN) A device (10) is provided for preventing rewetting in a pulp washer (100), with two press rolls (2), arranged to rotate in opposite directions and having permeable outer surfaces (4), inside of which filtrate channels (6) are arranged. The device (10) comprises an anti-rewet beam (12), the cross-section of which forms a closed shape. The anti-rewet beam in turn comprises a filtrate barrier (12a) positioned towards the outer wall (6a) of the filtrate channel to prevent flow of liquid from the trailing part of the filtrate channel to the outer surface of the press roll, a support member (12b) positioned towards the rear side wall (6d) of the filtrate channel, and at least one intermediate beam portion (12c, 12c'), interconnecting the filtrate barrier and the support member, to form the closed beam shape.
