Abstract
An apparatus is disclosed for removing the dross ridges which may be formed on the sides and ends of a metal workpiece during torch cutting of the workpiece. The apparatus includes a workpiece support table and a pair of workpiece transport devices for moving the workpiece both transversely and longitudinally on the table. A plurality of aligned and pivotally 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.
