Abstract
Abstract Apparatus for marking an elongated workpiece comprising a marking wheel rotatably mounted in a yoke which is movable against the workpiece as the workpiece is moving, is mounted for horizontal adjustment, vertical adjustment, and arcuate or angular adjustment on a curved way in a plane normal to the path of travel of the workpiece. The marking wheel may contain die stamps or ink stamps. The apparatus continuously marks structural shapes, bars, rounds, etc., or flat product in either a hot or cold process.
