Abstract: A process and apparatus for molding a plurality of articles of hardenable material such as plastic which requires each article to be maintained under heat and pressure for a cure interval. A molding press is utilized wherein there is placed a first open mold assembly having spaced die halves between supporting mold platens. At least one of the die halves has a resilient pressure pad between the die and the mold platen supporting the die half. The press is closed to maintain the mold platens in a first force applying position having a slight gap between the die halves and locking the platens in the first position. The mold assembly is removed while in its first locked position from the press and gas from the curing material is evacuated through the gap between the die halves while heating the material.

Abstract: An article accumulator and transfer system and method is provided for combining the transfer of articles from a loading station to an unloading station and the accumulation of articles to avoid prolonged, interrupted operation of the unloading station in the event the loading station is inoperative. The method includes a first primary operation which intermittently moves and stops a continuous conveyor having a plurality of article stations between the loading and unloading stations, placing articles on the conveyor at the loading station when the conveyor is stopped and there is no article on the conveyor article station at the loading station at a rate greater than the rate at which the articles are removed at the unloading station and removing articles from non-sequential article stations of the conveyor when at the unloading station and the conveyor is stopped.
