Rotary embossing die counter
Abstract
Abstract A ROTARY COUNTER FOR USE AGAINST A ROTARY EMBOSSING OR FOIL STAMPING DIE HAVING A MODELED SURFACE PRESENTING A DESIGN. THE COUNTER IS PREPARED BY APPLYING SEVERAL LAYERS OF AN ULTRAVIOLET SENSITIVE, THERMOSETTING SYNTHETIC RESIN REINFORCED WITH GLASS CLOTH TO A COUNTER ROLL. AFTER PARTIAL CURING OF THE RESIN TO REDUCE THE TACKINESS THEREOF, THE DIE IS ROTATED AGAINST THE RESIN BLANKET ON THE COUNTER ROLL TO CAUSE THE OUTER FACE OF THE BLANKET TO ASSUME A SHAPE WHICH IS THE REVERSE OF THE DIE. A SHEET OF LEAD FOIL IS INSERTED BETWEEN THE DIE AND THE DEFORMED RESIN TO PROVIDE PAPER CLEARANCE. ROTATION OF THE DIE AGAINST THE LEAD FOIL CAUSED THE LATTER TO BE DEFORMED AND THE SYNTHETIC RESIN TO ASSUME THE CONFIGURATION OF THE ADJACENT FACE OF THE FOIL. FINAL CURE OF THE RESIN ON THE COUNTER ROLL IS EFFECTED BY APPLICATION OF ULTRAVIOLET ENERGY TO THE RESIN DURING ROTATION OF THE COUNTER ROLL.
