ABSTRACT:
An apparatus for determining the top and the bottom surface of a metallic workpiece, such as a steel slab. The apparatus is positioned proximate to the workpiece and includes a rail beam which may be translated across the width of the workpiece. A first arm is pivotally coupled to a first end of the rail beam and a second arm is pivotally coupled to a second end of the rail beam. The two arms are pivotally interconnected at top ends thereof by a tie rod, thereby forming three sides of a parallelogram. Deflection of the first arm during translation of the rail beam across causes a similar deflection of the second arm. The deflection of the second arm may be recorded, thereby recreating the surface profile of the workpiece.
