  • Press with easily exchangeable proof plates
    Patent number: 4490103
    Abstract: In a press operable for movements of proof plate exchangeably mounted on an end of a press die into and out of a mold, and wherein the proof plate normally does not exceed a position wherein its topmost portion is at most flush with a topmost portion of the mold during the movements, the improvement includes a drive device independent of the movements for moving the proof plate beyond the topmost portion of the mold, so that the proof plate projects through the mold, and is thereby freely accessible for the purpose of being replaced.
