Abstract

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.

Abstract

A graphic arts die assembly includes a die carrier plate, a die, and a die adjuster. The die is adjustably supported on the die carrier plate. The die presents an outer margin and an engraved surface within the outer margin. The die further presents an adjuster surface that extends transversely relative to the engraved surface. The die adjuster shiftably engages the adjuster surface, with shifting movement of the die adjuster causing relative movement between the die and the die carrier plate.

Abstract

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.

Abstract

A graphic arts die and support plate assembly is provided that is adapted to be mounted as a unit on the chase of a flat bed or rotary graphic arts press. The assembly includes a plurality of spaced individual dies fixedly mounted in predetermined relative relationship on a support plate member of the unit. Alignment holes in each die that register with orifices in the support plate member are adapted to receive temporary alignment pins thereby assuring correct positioning of the dies with respect to one another on the support plate member until the dies are affixed to the support plate member. Makeready and die lock-up time of the press is significantly decreased because all dies of the assembly may be preregistered with a design artwork before mounting of the die and support assembly on the press. A series of graphic arts die units are also provided that are adapted to be mounted as an assembly encompassing more than 180° of the circumference of a rotary press chase. The graphic arts die units have die support plate members that may be aligned with indicia on the press chase, and that have notch structure receiving a tool for facilitating alignment and spacing between adjacent die support plate members. Cutouts in the die support plate members permit manual selective shifting of a die relative to the die support plate member therefor using a tool received in a cutout and engageable with the die.
