Abstract
The present invention relates to a device for partial decoating and/or machining removal of a steel sheet coated with a metal coating and/or provided with a parasitic layer, wherein the device has a machining tool in the form of a scraping roller and wherein the scraping roller comprises a cutting edge for scraping the metal coating and/or parasitic layer off the steel-sheet surface, and wherein furthermore the scraping roller is rotatable about a rotation axis perpendicular to a main plane of extent of the steel sheet, the scraping roller has a circumferential face which is concentric with the rotation axis and in which at least one circumferential groove is formed, the groove has two lateral groove boundary faces that originate from the groove bottom face, wherein at least one of the two groove boundary faces has the cutting edge and the device is configured such that during decoating and/or machining removal, the at least one cutting edge scrapes over the steel-sheet edge in a manner parallel to the main plane of extent of the steel sheet.
