The male blanking die/female blanking die combination includes a specifically-configured male stripping die. Such male stripping die includes a template having a particularly-specified perimeter, the template including a plurality of foam plastic pads which are removably secured to the undersurface of the template, the template being accurately secured at a predetermined position to the underface of a movable upper plate of the blanking station of the die cutting machine. The male blanking die/female blanking die combination also includes a specifically-configured female blanking die. Such female stripping die includes a rectangular framework and a plurality of grid support members, each grid support member having a slot across its upper face, the grid support members being selectively disposed along the internal perimeter of the rectangular framework. A grid is provided comprising a plurality of intersecting rails, the pattern of the intersecting rails having a predefined shape. The grid is disposed within the slots atop the grid support members. A plurality of jogger members are provided which are selectively disposed along the internal perimeter of the rectangular framework, each jogging member having a particularly-recited structure. The plurality of jogger members are oriented along the internal perimeter of the rectangular framework in a particularly-recited way. The female blanking die is accurately secured at a predetermined position atop a lower fixed plate of the blanking station of the die cutting machine. The male blanking die and the female blanking die are accurately aligned to cooperate to press and separate the carton blanks from a web holding them together, and to force the separated cartons through aligned openings in the female blanking die.
