Abstract: A two-piece die for simultaneously embossing a pattern into a web of material and cutting out that pattern from the web includes a flexible die member having male embossing patterns surrounded by a male die cutting edge. A base die member has female patterns into which the male patterns on the base die fit, but no corresponding groove for the male die cutting edge. The two members of the die set are held in a register by upper and lower outwardly projecting register tabs on the base die that are received into corresponding register slots in the flexible die and a register bar raised above the surface of the flexible die along side the register slots are on. An edge of the base die lying between the register tabs butts against the register bar. The die members, with a paper between them, are run through a flat bed press to produce embossed cut out patterns.

Abstract: A die that may be rotated relative to a die holder to form an opening in different types of envelopes, cardboard boxes or other type of blanks or webs is provided. The window opening in an envelope blank is formed by using a sheet of material having a top surface and an outer periphery. A raised portion extends from the top surface of the sheet and includes a cutting edge adapted to cut the envelope blank to form the opening. A coupling means are included to selectively couple the die with the die holder in at least two orientations so that the position of said sheet may be changed relative to the die holder to alter the location in which said cutting portion forms the opening in the envelope blank.
