ABSTRACT:
A sheet material is advanced to a first location where cutting tools cut into it but not through it along the outline of the desired blank. Thereupon the sheet material and the cutting tools are jointly advanced to a second location where the cutting tools cut completely through the sheet material along the outline, and subsequently the thus-severed blank and the surrounding sheet material scrap are removed separately from the second location.
