Abstract

The invention relates to a method for the decoating at least in part of blanks made of metal which are coated on one or both sides in regions, which have a main extension direction, wherein the regions to be decoated can extend in both a straight or curved manner in the main extension direction. The invention further relates to a device for the decoating at least in part of a coated blank in order to carry out the method according to the invention. A method is provided in which the blank is placed on a blank support of a press and during the closing movement of the press at least one scraping knife preferably completely removes the coating of the blank by scraping substantially perpendicular to the main extension direction of the region of the blank to be decoated.
