MAGNETIC CHASE AND GRAPHIC ARTS DIE ASSEMBLY WITH SELECTIVELY ACTUATABLE MEANS FOR RAISING AND SUPPORTING THE DIE PLATE DURING ALIGNMENT

摘要

A graphic arts die assembly and chase for use in a graphic arts press are disclosed for use in conjunction with a press. The die assembly includes a die plate formed at least partially of ferromagnetic material and a chase with a plurality of magnet assemblies configured to provide a magnetic coupling force to selectively secure the die plate to the chase. The chase includes an actuatable releasing assembly to exert a disengagement force to separate the magnetic securement between the plates.
