Abstract
An automatic badge making machine comprises a die assembly including a first and second die set relatively movable to form a badge or button from a plurality of badge parts initially placed in one of the die sets. A motor powered drive is provided for relatively moving one of the die sets in an operating cycle comprising a plurality of successive strokes toward and away from the second die set to shape and form a badge between the facing surfaces. A protective safety shield is provided for movement between an open position exposing a work area to permit access to the die sets for loading/unloading badge parts/badges and a closed position enclosing the work area during a badge making operating cycle. The shield comprises a component of a safety system provided for preventing operation of the motor whenever the protective safety shield is out of the closed position. The badge maker also includes a circuit for automatically returning the die sets to an open position whenever excessive forces between die sets are encountered during a badge making operating cycle.
