ABSTRACT:
A die stamping device for cutting, scoring or creasing a pattern of shapes onto laminar material, comprises a die cylinder having a solid cylindrical core with a coating of setting material such as plastics in which are fitted cutting or scoring blades the radially outer surfaces of which define the pattern to be cut or creased onto laminar material passed in sheet or web form between the die cylinder and a smooth pressure cylinder, which may be provided with cooperating elements, such as resilient blocks or engraved recesses to cooperate with the scoring or creasing blades; the die cylinder is made by a process involving forming a pattern on the outer surface of the coating by photographic techniques, and then removing the coating from the solid cylindrical core to facilitate cutting out the openings to receive the blades.
