ABSTRACT:
An improved method and apparatus for fabricating reticular sheet material utilizes dies for shearing a sheet of metal into interconnected strands, mandrels for bending alternate interconnections of the metal in opposite directions to form ridges and valleys between the strands, and inserting punches into the sheared areas between strands while holding the ridges with other punches to form uniform openings in the areas between the strands.
