摘要： The present invention relates to a method for the production of a screen and to a screen for the treatment of a fibrous material suspension suitable for the production of a fibrous material web, the screen including at least two screen layers that are connected to each other and have apertures, at least some of the apertures being arranged in such a way that the result is screen openings leading through the screen. The production of the screen is simplified in that some of the apertures are arranged in such a way that the result is recesses on the front side of the screen which do not pass through the screen, and at least the apertures forming the recesses are introduced into the screen layers before the latter are connected.
