Knife assembly for a chipper

Abstract

A knife assembly for a chipper, which is intended to be installed in the knife frame includes a counter knife, a reversible knife including two cutting bevel edges, and a clamp. In addition, the knife assembly includes securing devices for securing the clamp and at least one locking piece running parallel to the longitudinal axis of the reversible knife to prevent lateral movement of the reversible knife relative to the counter knife. The reversible knife, the counter knife, and the locking piece are arranged in such a way that the position of the reversible knife relative to the knife frame can be set as desired. The locking piece is also arranged to form a fixed part of the reversible knife or the counter knife, and the counter knife is fitted to the knife frame using shape-locking.

Description

technical field [0001] The invention relates to a knife assembly for a chipper to be mounted in a knife holder forming part of the chipper, the knife assembly comprising: [0002] Opposite knife, assembled on the knife holder, [0003] Symmetrical reversible knife, held by the counter knife, having two beveled cutting edges on opposite sides, one of which protrudes further from the holder than the counter knife, [0004] a clamp arranged to press the reversible knife by the opposite side of the opposed knife, [0005] fasteners for securing the clamp and securing it to the tool holder, thereby compressing the reversible knife between the clamp and the opposing knife, and [0006] at least one locking block extending parallel to the longitudinal axis of the reversible knife and extending on both sides of the boundary surface 2 between the reversible knife and the counter knife in order to prevent lateral movement of the reversible knife relative to the counter knife , [00...
