MAGNETIC SUPPORT PLATE FOR CLADDED STEEL AND STEEL-BACKED POLYMER STAMPING/BLOCKING AND EMBOSSING GRAPHIC ARTS DIES

摘要

A magnetic support plate for cladded steel and steel-backed polymer stamping/blocking and embossing graphic arts dies is provided in which a non-ferrous, rectangular support member (14, 114, 214) made up of a plate (26, 126, 226) has a die mounting surface (24) for complementally receiving the graphic arts die assembly (12). The plate (26, 126, 226) has a series of elongated recesses or cavities (28, 128, 228) in one face thereof, with each of the cavities being provided with two rectangular magnets that are located in spaced relationship one from another. The two magnets within each cavity are disposed in positions with the magnetic north and south poles thereof opposite one another. A ferro-magnetic component (36) in the form of a steel plate or strip is provided within each cavity in bridging, contacting relationship to both of the magnets within each cavity. The magnets serve to magnetically attract and hold the cladded steel or steel-backed polymer stamping/blocking and embossing dies against the surface (24) of plate (26, 126, 226). The ferro-magnetic component (36) significantly enhances the magnetic attractive force of the magnets.
