<p>Apparatus for, and a process of, sector engraving metal elements is disclosed. The apparatus includes an engraving roller having a particular pattern formed thereon and a workpiece mounting system which is capable of translational movement within two mutually orthogonal directions. When the engraving process is to be performed, the engraving roller is held in contact with the workpiece, and as a result of a first translational movement of the workpiece mounting system in a first direction, a predetermined sector of the engraving roller is caused to contact a predetermined portion of the workpiece whereby a predetermined portion of the roller pattern is reproduced upon the workpiece. Movement of the workpiece mounting system in the second direction causes another sector of the engraving roller to be aligned with another portion of the workpiece whereupon repeated movement of the workpiece mounting system in the first direction serves to reproduce a new portion of the pattern upon the new portion of the workpiece.</p> |
