Abstract
Disclosed is a die press with a base, at least two cam members spaced from the base, an upper platen located between the base and the two cam members to define a space for a die, the upper platen being generally parallel to the base, the upper platen also being attached to the two cam members so that when the two cam members are actuated, the upper platen is moveable relative to the base, and a linkage connecting the two cam members so that the two cam members move in unison relative to each other when actuated.
