A non-contact cutting system and method cuts a strip of metal into narrow strands having varying width defining successive, longitudinally spaced portions from which end product pieces can be removed. An array of cutting heads is arranged to project cutting beams onto the surface of a metal strip to cut the strand edges in a predetermined pattern whereby a maximum number of end product piece areas is defined on the strip.
