Abstract
A frame assembly for a lower blanking tool of a carton die cutting machine. The frame assembly includes an outer frame comprised of a pair of opposite longitudinally extending side rails and a pair of opposite cross rails extending crosswise between the side rails. Each of the cross rails has a T-shaped slot formed therein opening to its inner surface, and each of the side rails have a T-shaped slot formed therein opening to its upper surface. Each slot extends downwardly at an acute angle with respect to a horizontal plane. A plurality of corner pieces rigidly interconnect the rails together with fasteners extending into the T-shaped slots of adjacent side and cross rails so that when tightened, the corner pieces function like clamps to rigidly interconnect the rails together.

A frame assembly for a lower blanking tool of a carton die cutting machine, comprising:
- an outer frame for supporting a sheet of die cut paper material during a blanking operation, said sheet of paper material defining a substantially horizontal plane, and said outer frame comprising:
- a pair of opposite, spaced apart longitudinally extending side rails, and
- a pair of opposite, spaced apart cross rails extending crosswise between said side rails;
- each of said cross rails having an inner surface disposed substantially transverse to the plane defined by said sheet of paper material and having a T-shaped slot formed therein opening to said inner surface, each of said side rails having an upper surface disposed substantially parallel to the plane defined by said sheet of paper material and having a T-shaped slot formed therein opening to said upper surface, said T-shaped slots each defining a downwardly extending axis disposed at an acute angle with respect to the plane defined by said sheet of paper material;
- and
- a plurality of corner pieces rigidly interconnecting said rails together, said corner pieces each include fasteners extending into the T-shaped slots of adjacent side and cross rails.
A frame member for a lower blanking tool frame assembly of a carton die cutting machine, comprising:
- an elongate rail having an upper surface, a lower surface, an outer surface and an inner surface, and
- said rail having a bolt-receiving T-shaped slot formed therein, said slot opening to said inner surface and defining a downwardly extending axis disposed at an acute angle with respect to said inner surface.
A corner piece for interconnecting frame members of a lower blanking tool frame assembly used in a carton die cutting machine, comprising:
- an L-shaped body having a horizontal plate member defining a substantially flat upper face, a substantially flat opposite lower face, an inside face, an opposite outside face, and an end face, and an upright plate member defining a substantially flat inner face contiguous with said upper face, a substantially flat outer face contiguous with said lower face, an inside face contiguous with the inside face of said horizontal plate member, an opposite outside face contiguous with the outside face of said horizontal plate member, and a top face;
- said horizontal plate member having at least one outwardly extending bolt-receiving bore formed therethrough, said outwardly extending bore defining an axis disposed at an acute angle with respect to said upper face;
- said upright plate member having at least one downwardly extending bolt-receiving bore formed therethrough, said downwardly extending bore defining an axis disposed at an acute angle with respect to said inner face;
- a lip projecting outwardly from the outer face of said upright plate member;
- and
- a tenon projecting downwardly from the lower face of said horizontal plate member.
