Abstract
Method and apparatus for control of a toggle operated press to effectively set relative position between a fixed platen and a die height platen. The toggle crosshead is placed at a position required to achieve a desired press clamp force. The die height platen is advanced toward the fixed platen until minute motion of the toggle crosshead away from the fixed platen is detected whereat advance of the die height platen is ceased. In the relative position of the die height platen and fixed platen results in contact of the mold sections prior to the crosshead being placed at the required position, the crosshead is retracted a predetermined distance and then advanced to the required position. Desired die height setting is achieved without repeated iterations of a die height setting procedure.
