Stripper unit

Abstract

A stripper unit that includes an unround cylindrical pressure plate, wherein the outer contour of the unround cylinder shape in a cross section transversely through the pressure plate defines the installation space thereof transversely to the direction of extent of the cylinder. A stripper plate is also provided, placed on the end face of the pressure plate and mounted on spring elements such that it can be moved up and down with respect to the pressure plate, wherein the stripper plate is formed geometrically in such a way that it fits completely flush within the outer contour of the cylinder shape of the pressure plate and does not protrude beyond it.
