The fine-cutting methods known from the prior art comprise linear transport units for the linear transport of the sheet metal strip or of the metal workpieces along a direction of travel of the sheet metal strip. The direction of passage is arranged in particular parallel to a horizontal plane and is driven by a belt feed system of a press.
