摘要

The invention relates to a plate (2) for a plate clutch or brake (4) with a first friction surface (28) and a second friction surface (34) facing away from the first friction surface (28), in which recesses and / or grooves (40, 42, 44) are provided. In the first friction surface (28) there is a first type of depressions or / and grooves (40) which is produced by a material-forming and / or material-forming or / and non-material-removing first manufacturing method, and in the second friction surface (34) there is one second type of recesses and / or grooves (42) is provided, which is generated by a material-removing second manufacturing process. In addition, the present invention relates to a multi-plate clutch or brake (4) with such a plate (2) and a method for producing such a plate (2).
