Abstract
A demolding device for use in an imprint machine, in which a foil is intermittently passed in a feed direction over a press region where a stamp is pressed against the foil for imprinting a surface pattern. The demolding device includes a carrier, a pressing roller mounted in the carrier, and a demolding roller mounted parallel to the pressing roller in the carrier, wherein the carrier is configured to slide over the press region against the feed direction while rolling the foil under the pressing roller and over the demolding roller for detaching the foil from the stamp after imprinting of the pattern.
