Abstract
A bed knife that acts together with a cutting blade moved past it, particularly for granulating plastic strands, consisting of individual aligned sections of the same type that are fastened to a supporting beam and whose knife edge consists of a cutter material. Each section consists essentially of ceramic cutter material and extends over the areas of feed and delivery of the material to be cut of the cut material. The section is provided with a cutout running in the direction of the bed knife that is aligned with the cutouts of all of the sections and changes into an outer surface of the section as a throat in comparison with the corresponding dimension of the cutout, with the cutouts containing a continuous bar extending through several sections. The bar presses the section against the supporting beam by means of screws passing through the throat that penetrate into the bar, with sections being connected to one another positively by the bar.
