Abstract
A friction lining for a multiple disk clutch or a multiple disk brake, with grooves extending in a direction from a radially inner lining edge to a radially outer lining edge. Individual ones of these grooves exhibit pronounced rectangular or orthogonal transistion areas between the groove and a surface of the friction lining with the remaining grooves exhibiting non-rectangular transistion areas of the groove edges to the friction surface of the friction lining. A plurality of grooves provided non-rectangular transistional areas extend linearly and are not connected to the grooves having the rectangular transistional areas. At least one groove having a rectangular transistional area and being open at least toward the outer lining edge is disposed between two circumferentially adjacent or neighboring grooves having a non-rectangular transistional area.
