APPARATUS AND METHOD FOR REMOVING DROSS RIDGES FROM A METAL WORKPIECE Abstract of the Disclosure An apparatus and method are disclosed for removing the dross ridges which are formed on the lower surface of a metal workpiece during torch cutting of the workpiece. In one embodiment, the apparatus includes a cutting blade having a generally flat outer surface and a cutting edge along each of its two opposite sides. The blade is positioned to extend across and below the workpiece path of travel, and the blade is rotatable between a neutral position wherein the blade is below the pass line of the workpiece, and opposite tilted positions in which one or the other of the cutting edges engages the lower dross carrying surface of the work- piece, and so that each cutting edge is adapted to engage and remove a dross ridge on the workpiece. In another embodiment, the apparatus includes a workpiece support table and a pair of workpiece transport devices for moving the workpiece both transversely and longitu- dinally on the table. A plurality of aligned and pivo- tally mounted cutting blades extend along each side of the table, and a pair of pivotally mounted transverse cutting blades are mounted adjacent respective ends of the table. In operation, the workpiece is moved over the blades along each side of the table, and also over both of the transverse blades, and such that the blades engage and remove the dross ridges along the two sides and the two ends of the workpiece.
