A rotary die-cutter for cutting a piece of material or scrap out of a printing material such as paper, includes a die-cutting cylinder and an associated impression cylinder. The die-cutting cylinder is connected to a vacuum source. A die-cutting tool which is disposed on the die-cutting cylinder includes at least one die-cutting knife having a closed form and a suction opening within the closed form. A cylinder cover is disposed on the impression cylinder. At least one raised or recessed first guide element is disposed within the closed form for guiding suction air and/or at least one recessed or raised second guide element is disposed in the cylinder cover for guiding air. The scrap to be removed from the printing material can therefore be transported with the die-cutting cylinder and ejected from the die-cutting tool or knife in a trouble-free way.
