Abstract

In a method for manufacturing friction linings with or without an intermediate layer by compressing the friction material mixtures in a mold of a press during a pressing process comprising at least one pressing cycle, wherein a press control unit controls a plurality of manipulated variables individually or in combination with each other to attain a given lining property (controlled variable) of the friction linings, it is provided that at least one characteristic value representative of the lining property of the friction linings is measured in a first pressing cycle or in a plurality of pressing cycles, and that the manipulated variables are controlled in dependence on the at least one measured characteristic value of the current pressing cycle, the subsequent pressing cycles and/or the subsequent pressing processes.
