  • Patent number: 5613898
    Abstract: A device for producing inclines and/or grooves on friction pads, such as brake pads for motor vehicles comprises a table with a mount for the brake pads. The table is linearly moved on a carriage below flat, truncated-conical grind disks which are disposed in pairs and oriented mutually mirror-symmetrical. The table is swivellable about an axis oriented tranversely to the travel direction. The swivel movement is effected by at least one pneumatic cylinder. Control valves or control switches run onto cam ramps on cam bars when the table is driven forward and they initiate the swivel operation of the table. The friction pad is operated on when the table is in the downwardly or upwardly pivoted position, whereby the table is preferably locked in its position during the various grinding operations.
