An apparatus and method are disclosed for removing the dross ridges which are formed on the lower surface of a metal workpiece (14) during torch cutting of the workpiece. The workpiece is moved over a pivotable cutting blade (20), a cutting edge (29) of which is biased upwardly against the underside of the workpiece. This cutting edge removes a dress ridge (17) from the trailing lower edge of the workpiece. The direction of travel of the workpiece can then be reversed and another cutting edge (28), facing in the 19 opposite direction, can be pivoted upwards to remove a dress ridge from the opposite lower edge. |
