Abstract

An arcuate die board formed as a multi-layered paperboard structure. The die board is initially produced as a full cylindrical paperboard tube, which is subsequently cut lengthwise to form two or more part-cylindrical portions each of which is used to fabricate a die board. The die board is then cut to form the slots in its outer surface for mounting die tools. The multi-layered paperboard tube can be spirally wound, convolutely wound, or formed by a linear draw process. The part--cylindrical wall is formed predominantly, substantially entirely, or entirely of paperboard plies adhesively laminated together.

Claims (25)

1. A die board for a rotary die, comprising:
an arcuate part-cylindrical wall having an outer part-cylindrical surface and an inner part-cylindrical surface; and wherein the part-cylindrical wall is formed at least predominantly of a plurality of paperboard plies adhesively laminated together.
2. The die board of claim 1, further comprising a plurality of slots formed in the outer part-cylindrical surface of the wall for receiving die tools.
3. The die board of claim 1, wherein the part-cylindrical wall is formed substantially entirely of a plurality of paperboard plies adhesively laminated together.
4. The die board of claim 1, wherein the inner part-cylindrical surface has a diameter of approximately 482 to 489 mm.
5. The die board of claim 4, wherein the part-cylindrical wall has a thickness of approximately 12.6 to 13.3 mm.
6. The die board of claim 1, wherein the plurality of paperboard plies include paperboard plies of at least two different types.
7. The die board of claim 1, wherein an outermost ply of the die board is substantially thinner than at least some of the other plies.
8. The die board of claim 1, wherein the plies include at least a first moisture-barrier ply.
9. The die board of claim 8, wherein the first moisture-barrier ply comprises a laminate of at least one paper layer and at least one substantially moisture-impervious layer.
10. The die board of claim 8, wherein the first moisture-barrier ply is proximate a radially outer surface of the die board.
11. The die board of claim 10, further comprising a second moisture-barrier ply proximate the radially outer surface of the die board.
12. The die board of claim 9, wherein the first moisture-barrier ply is proximate a radially inner surface of the die board.
13. The die board of claim 12, further comprising a second moisture-barrier ply proximate a radially outer surface of the die board.
14. The die board of claim 13, further comprising a third moisture-barrier ply located radially inwardly of the first and second moisture-barrier plies.
15. The die board of claim 13, wherein there is a substantially greater number of paperboard plies than moisture-barrier plies.
16. The die board of claim 1, comprising approximately 15 to 25 paperboard plies ranging in thickness from about 0.01 inch to about 0.03 inch, the die board having a wall thickness of about 0.4 to 0.6 inch.
17. A method for making die boards for a rotary die, comprising the steps of:
wrapping a plurality plies, predominantly made up of a plurality of paperboard plies, one atop another about a cylindrical mandrel and adhering the plies to one another to form a hollow predominantly paperboard tube on the mandrel;
removing the tube from the mandrel; and cutting the tube lengthwise to form at least two part-cylindrical portions each formed by a part-cylindrical wall having a part-cylindrical inner surface and a part-cylindrical outer surface.
18. The method of claim 17, further comprising the step of:
forming a pattern of slots in the part-cylindrical outer surface of each of the part-cylindrical portions, the slots being configured to hold die tools.
19. The method of claim 17, wherein the wrapping step comprises helically wrapping the plies about the cylindrical mandrel.
20. The method of claim 17, wherein the wrapping step comprises wrapping plies of at least two different types.
21. The method of claim 17, wherein the wrapping step includes wrapping at least one moisture-barrier ply.
22. The method of claim 17, wherein the wrapping step includes wrapping at least one moisture-barrier ply in the form of a laminate having at least one paper layer and at least one substantially moisture-impervious layer.
23. The method of claim 22, wherein the wrapping step includes wrapping at least two of said moisture-barrier plies each in the form of said laminate.
24. The method of claim 17, wherein the wrapping step includes wrapping a plurality of paperboard plies having a moisture content not greater than about 4%.
25. The method of claim 24, wherein the wrapping step further comprises wrapping at least one moisture-barrier ply in the form of a laminate having at least one paper layer and at least one substantially moisture-impervious layer.
