Abstract: A process of producing metal blanks with different thicknesses from a metallic material includes: producing sheet metal blanks from a band material; changing the temperature of the metal blanks such that, in the blanks, a plurality of regions is produced with different temperatures; rolling the metal blanks having regions with different temperatures in a rolling tool with a roll gap setting, wherein the roll gap setting is kept constant during the operation of rolling the metal blanks, wherein, due to the regions with different temperatures in the sheet metal blanks, portions are produced with different thicknesses. The invention also relates to a suitable device for producing sheet metal blanks with different thicknesses from a metallic material.

Abstract: A brake or clutch lining (10; 12) has a friction lining (22) arranged on a carrier plate (20). For purposes of detecting a critical operating temperature, an electrically conductive material (24) that has a phase-transition temperature that falls within the range of the critical operating temperature of the friction lining to be detected is provided in at least one place in the friction lining (22).

Abstract: A friction lining (4) of a brake is made of a friction material (41) and has a grid (1) that is made of an elastic filling material embedded into the friction material. As a first step, the grid (1) made of the filling material is placed into a friction-lining compression mold in such a way that one grid side ends with a friction surface. Essentially pulverulent friction material is then filled into the compression mold and press-molded with the grid (1) in such a manner that the interstices in the grid and between the compression mold and the grid are filled up with friction material, forming a flush friction surface. During the press-molding procedure, the filling material grid (1) is subjected to high pressing forces in the tangential as well as radial directions.
