Abstract
A cutting and scoring die useful for die-cutting or scoring paperboard or plastic materials including a solid base material that is cavernous and slotted for steel rule protrusion through the top surface thereof. The steel rule is then anchored to the base material by the use of a semi-rigid filler material.
Claims24
A die used for cutting and scoring paperboard and plastic material comprising:
- a. a unitary, substantially solid base member having at least one slot cut in a surface thereof;
- b. a steel rule having a base edge and an operative edge;
- c. a cavity formed in said base member to communicate with said slot, said slot and said cavity defining a passage through which said rule is inserted so that said operative edge of said rule extends up through the top surface of said base member;
- d. semi-rigid filling material filling said cavity, said semi-rigid material filling said cavity adapted to anchor said steel rule to said base member by engaging the opposed surfaces of said rule and said cavity substantially throughout the surface areas of said opposed surfaces.

A die used for cutting and scoring paperboard and plastic material comprising:
- a. a lower base member element having a slot formed in the bottom surface thereof;
- b. an upper base member element having a slot formed in the top surface thereof adapted to align with said lower base slot;
- c. a cavity located in the top surface of said lower base element, said cavity being connected to said first slot;
- d. a cavity located in the bottom surface of said upper base element, said cavity being connected to said second slot, said upper base element cavity superposed on said lower base element cavity;
- e. a steel rule having a base edge and an operative edge, said base edge placed in said lower base element slot, said operative edge extending up through said upper base element slot;
- and
- f. semi-rigid filling material filling said cavities, said semi-rigid material adapted to anchor said steel rule to said bases.

A die for cutting and scoring paperboard material comprising:
- a. an upper base member element having a slot formed therethrough;
- b. a lower base member element having a slot formed in the bottom portion thereof;
- said lower base element slot adapted to align with said upper base element slot;
- c. a cavity formed in the top portion of said lower base element connected to said second slot and located between said aligning slots;
- d. a steel rule having a base edge and an operative edge, said base edge placed in said slot formed in said lower base element, said operative edge extending up through said upper base element slot;
- and
- e. semi-rigid filler material filling said cavity, said semi-rigid material adapted to anchor said steel rule to said lower base element.

A die for cutting and scoring paperboard material comprising;
- a. a steel rule having an operative edge and a base edge;
- b. a base member having a slot formed into the top surface thereof;
- c. a cavity formed in the lower surface of said base member, said cavity aligning with said slot, said cavity and said slot defining a passage through which said rule extends so that said operative edge of said rule extends upwardly through said slot;
- and
- d. semi-rigid filler material filling said cavity, said semi-rigid material adapted to anchor said steel rule to said lower base.

A die for cutting said scoring paperboard material comprising:
- a. a steel rule having an operative edge and a base edge;
- b. a base member having aligned slots formed in the top and bottom surfaces thereof;
- c. a cavity formed in said base member intermediate said aligned top and bottom slots and in communication therewith, said slots and said cavity defining a passage through which said rule extends so that said operative edge of said rule extends upwardly through said slot;
- and
- d. semi-rigid filler material filling said cavity, said semi-rigid material adapted to anchor said steel rule to said lower base.
2 more elements
A method for forming a die to be used in cutting and scoring of paperboard or plastic material comprising the steps of:
- a. forming aligning slots in the top and bottom portion of a base member;
- b. forming a cavity between and connected to said slots by hollowing said base member from an edgewise portion thereof;
- c. inserting a steel rule in said slots so that the operative edge of said rule extends upwardly through said slot formed in the top portion of said base member;
- and
- d. placing a semi-rigid filler material into said cavity to anchor said steel rule.

A method for forming a die to be used in cutting and scoring of paperboard and plastic material comprising the steps of:
- a. forming a slot in the top side portion of an upper base member element;
- b. forming a slot in the bottom side portion of a lower base member element to align with said first slot;
- c. forming a cavity in the bottom portion of said upper base member element to communicate with said first slot, said cavity forming an opening in the bottom surface of said upper base member element;
- d. forming a second cavity in the top side portion of said lower base member element to communicate with said second slot, said second cavity forming an opening in the top surface of said lower base member element;
- e. superposing said upper base element cavity on said lower base element cavity;
- f. inserting a steel rule through said slots so that the operative edge of said rule extends upwardly through said first slot;
- and
- g. placing a semi-rigid filler material in said cavities to anchor said steel rule.
