Abstract: An apparatus for rotational stamping of stamped blanks with a defined geometry and size from a flat material comprises a tool, which comprises plural cutting dies and cutting holes. A first tool support rotates about a first axis and a second tool support rotates about a second axis. The first axis and the second axis are disposed in parallel and at a radial distance from one another, so that a radial offset for forming a pass-through gap for the flat material is provided between the first tool support and the second tool support. The cutting dies penetrate the cutting holes precisely fitting through counteracting rotation of the tool supports. The invention provides that the cutting dies and the cutting holes are disposed respectively on the circumference of the first tool support and on the circumference of the second tool support, in a seamless and alternating pattern, so that the flat material is processed into stamped blanks in a single step without lost or scrap pieces.
