Abstract
A method and apparatus for changing dies on a moving bolster for a press including a control circuit in combination with a cam-actuated deceleration valve. A cam is located at a predetermined location along a path for the moving bolster. Upon reaching the cam location when the bolster is moving toward or away from the press, the deceleration valve is actuated to inhibit and shut off a flow of air to air-operated motors on the bolster. Thereupon, the bolster moves to a stop at a predetermined location relative to the press.
