Abstract:
Sheet cutting means, preferably of the fluid jet nozzle type, is programmed for predetermined X-Y operation on a workpiece supported on a series of taut, unidirectional, spaced wires arranged substantially as a planar bed. As the nozzle is shifted in an X-Y plane parallel to and above the work, a drain cup is correspondingly moved beneath the wire bed to receive the spent pressure fluid for recirculation or other disposition. A transfer means comprised of uniformly spaced belts is movable heightwise between the wires to convey all cut parts and scrap, collectively in unchanged relation, to an unload station when the nozzle and cup are out of the way. Preferably a television screen displays for an attendant at the unloading zone of the machine a replica of the cut work as pre-programmed to facilitate his identification and disposition of the different cut-outs, for instance, shoe soles.
