Abstract: A control arrangement for a clutch and/or brake of a press, with the control arrangement including at least one of a clutch cylinder piston unit and a brake cylinder piston unit which opposes braking forces until a desired rotational speed is reached. The cylinder-piston units may be operationally controlled by at least one valve before the desired rotational speed is reached. The control arrangement is driven by at least two different pressures, with one of the pressures being at least approximately equal to a maximum clutch pressure or at least approximately equal to a pressure release, and the other pressure being a partial pressure which lies above a minimum response pressure of the clutch or below a counter pressure which triggers a minimal response pressure of the brake.

Abstract: A clutch and brake device for presses, punches, or the like, wherein a drive shaft of the presses or punches may be connected selectively to a flywheel employing a friction clutch and may be braked with respect to a frame of the press or punch by a friction brake. A bearing for the flywheel is provided at the frame on a tubular extension, with an end section of the drive shaft extending through the tubular extension. The friction clutch and friction brake are arranged on the end section of the drive shaft on a side facing away from the frame at a position beyond the bearing of the flywheel. The friction clutch engages at the flywheel by way of an annular support extending over the friction brake and attached to the flywheel. The friction brake is supported by way of a hollow support extended through the flywheel and encompassing the drive shaft.
