Grooving and stamping method and apparatus |
摘要 |
The method and apparatus described herein produce a tubular shelf post having a plurality of spaced apart annular grooves along the length thereof and stamped indicia on the outside surface of the post at various groove locations. A grooving and stamping roller is utilized to simultaneously groove and stamp the post with indicia, such roller being substantially larger in diameter relative to the post whereby a single roller revolution is sufficient to groove and stamp the post thereby eliminating double stampings.
