<p>A longitudinally movable band knife of a leather splitting machine, is guided between edge portions of first and second guide plates. The lower guide plate is stationary, and the upper guide plate is mounted for universal movement about a fulcrum point so that the upper guide plate can be displaced about a first axis perpendicular to the cutting edge of the band knife, and about a second axis parallel to the cutting edge and intersecting the first axis at a fulcrum point so that the upper edge portion always has full contact with the moving band knife when a preferably self-locking biassing device turns the upper guide plate about the second axis to press with the respective guide edge portion against the band knife. Turning of the upper guide plate about a third axis perpendicular to the plane of the intersecting first and second axes, is prevented by blocking parts on the lower guide plate, projecting into openings in the upper guide plate located along the second axis.</p> |
