a waste stripping station for a machine for die - cutting plate - like workpieces includes a perforated board which is positioned between an upper movable tool and a lower movable tool for supporting a plate - like workpiece carried into the station by grippers . waste bits of the workpiece are pinched between pins or elements of the upper and lower stripping tools and are carried vertically downward through perforations in the board . in order to provide clearance for the grippers , the perforated board is mounted to pivot around an upstream edge in order that its downstream edge may be lifted from a position allowing passage of the grippers to a position slightly lifting the plate - like workpiece .
