Abstract: A method and apparatus for dry engraving sheets of material wherein the method includes holding a sheet fixed in a first position while die stamping a layer of decorative foil thereon to present a specific design, shifting the sheet to a second position in alignment with an embossing die while retaining control over the sheet during shifting thereof, and holding the sheet fixed in the second position while embossing the sheet to form raised areas thereon underlying the foil design impression in exact registration therewith to simulate an engraved design. The apparatus includes a pair of side-by-side, oppositely reciprocable shuttle bars each having a series of vacuum ports therein which communicate with a vacuum source in timed relationship to the reciprocation of the respective bars. The shuttle bars thereby alternately shift new sheets into position for processing and cooperate to simultaneously hold fixed one sheet for foil design stamping thereof and another sheet for strategic area embossing thereof.
