ABSTRACT:
In blade holding devices sleeves are arranged concentrically about the blade securing screws, in order to relieve the blade securing screws from lateral shearing force components and vertically acting stripping forces resulting, when the blade slide is moved upward, from the friction between the blade and the scrap metal in the feed channel. For the removal of the blade, lateral wearing plates in the feed channel have to be removed. In order to permit the removal of the blade from the holding device without dismantling the wearing plates of the feed channel and, at the same time, retaining the sleeves, a short sleeve is provided, that, in an operational position of said scrap cutter, ascertains form-locking between the blade and the blade slide or the blade support and rests against a long spacing sleeve that is concentrically arranged about a shaft of the blade securing screw and is held by the blade securing nut. The short sleeve is also concentrically arranged about the shaft of the blade securing screw. After removal of the blade securing screws, the short sleeve may be slid toward the backside of the blade, permitting the removal of the blade in a downward direction. A dismantling of the lateral wearing plates is unnecessary.
