Abstract
An apparatus for removing the dross ridges which are formed on the lower surface of a metal workpiece during torch cutting of the workpiece. The apparatus includes a support beam having generally flat upper and lower surfaces, and a cutting edge extending longitudinally along each of its four corners. The beam is positioned to extend across and below the workpiece path of travel, and the beam is rotatable between a neutral position wherein one of the upper and lower surfaces is just below the pass line of the workpiece, and opposite tilted positions in which one of the cutting edges engages and removes a dross ridge on the lower surface of the workpiece. Each of the cutting edges comprises a plurality of separately pivotable cutting blades, so that the cutting edge formed by the blades is able to closely conform to a non-linear surface contour of the workpiece.
