Abstract

Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage. The stock material unit includes a continuous sheet of material including a tapered sheet section defined by a plurality of slanted folds and positioned adjacent to at least one face of the three-dimensional body, and a splice member. The splice member includes a base having a first side attached to a portion of the continuous sheet of foldable material that is positioned adjacent to the tapered sheet section and has an opposite, second side. The splice member also includes a connector that has a first portion non-removably attached to the tapered sheet section and a second portion removably attached to at least a portion of the second side of the base.

First claim

What is claimed is:

1. A stock material unit for a dunnage conversion machine, the stock material unit comprising:
a continuous sheet of folded material defining a three-dimensional body and including a tapered sheet section defined by a slanted fold and positioned adjacent to at least one face of the three-dimensional body; and
a splice member including:
a base having a first surface non-removably attached to a portion of the continuous sheet of folded material and a second surface opposite the first surface, the base being positioned adjacent to the tapered sheet section; and
a connector having a first portion non-removably attached to the tapered sheet section and a second reusable portion removably attached to at least a portion of the second surface of the base.

2. The stock material unit of claim 1 , wherein a periphery of the splice member is defined by two opposing linear sides and by two generally curved sides extending between the linear sides.

3. The stock material unit of claim 2 , wherein one side of the two linear sides is longer than the other side of the two linear sides.

4. The stock material unit of claim 1 , wherein the base has a greater area than the connector.

5. The stock material unit of claim 1 , wherein the continuous sheet of folded material is folded into a fanfold configuration.

6. The stock material unit of claim 5 , wherein the tapered sheet is folded over itself to define two fanfold layers of the continuous sheet of folded material.

7. The stock material unit of claim 1 , wherein the continuous sheet of folded material includes a plurality of substantially parallel folds that define opposing sheet sections that are folded along the continuous sheet of foldable material, and the slanted fold has a non-parallel orientation relative to the plurality of substantially parallel folds.

8. The stock material unit of claim 1 , wherein:
the slanted fold defines another tapered sheet section positioned adjacent to the tapered sheet section; and
the base is attached to at least a portion of the another tapered sheet section.

9. The stock material unit of claim 1 , wherein the second surface of the base includes a release layer.

10. The stock material unit of claim 1 , wherein the tapered sheet section includes four layers of the continuous sheet.

11. The stock material unit of claim 1 , wherein the connector is adhesively attached to the tapered sheet section.

12. The stock material unit of claim 11 , wherein the connector is adhesively attached to the base.

13. The stock material unit of claim 1 , wherein the connector includes an adhesive side facing upward and a non-adhesive side facing downward.

14. The stock material unit of claim 1 , wherein the tapered sheet section is generally triangular and includes a peak that is positioned near a longitudinal center of the three-dimensional body.

15. A dunnage conversion system comprising:
a dunnage conversion machine;
first and second stock material units for the dunnage conversion machine according to claim 1 ; and
a unit carrier securing the first and second stock material units,
wherein, the slanted fold of the first stock material unit is bent back on itself thereby detaching the second reusable portion of the first stock material unit from the base of the first stock material unit and exposing the second reusable portion of the first stock material unit for splicing to the second stock material unit, and
wherein the connector of the first stock material unit is sufficiently strong for splicing to the second stock material unit.

16. The stock material unit of claim 1 , further comprising a strap wrapped about the three-dimensional body to maintain the three-dimensional shape thereof and spaced transversely from the connector leaving the first portion of the connector exposed from the strap for attachment to another stock material unit.

17. The stock material unit of claim 16 , wherein the strap includes:
a load-spreading portion; and
a handle portion that is narrower than the load-spreading portion, wherein the strap is sufficiently strong for carrying the three-dimensional body from the handle portion.

18. The stock material unit of claim 1 , wherein the tapered sheet section is defined by a plurality of slanted folds.

19. The stock material unit of claim 18 , wherein the tapered sheet section includes a first fold line intersecting the slanted folds, such that each of the slanted folds is folded about the fold line.

20. The stock material unit of claim 19 , wherein the continuous sheet of folded material is fanfolded into a fanfold configuration by a plurality of parallel fanfold lines, which fanfold lines include the fold line.

21. The stock material unit of claim 20 , wherein the fanfold lines collectively define two of the faces of the three-dimensional body.

22. The stock material unit of claim 1 , further comprising a strap wrapped about the three-dimensional body, the strap being configured to secure and maintain the three-dimensional shape thereof and being positioned to leave the connector exposed to contact another stock material unit placed thereagainst.

23. The stock material unit of claim 1 , wherein the tapered sheet section includes a first fold line that intersects the slanted fold, such that the slanted fold is folded about the fold line.

24. The stock material unit of claim 1 , wherein an upper face of the three dimensional body comprises at least four exposed layers of the continuous sheet of folded material defined by the at least four fold lines.

25. A stock material unit for a dunnage conversion machine, the stock material unit comprising:
a rectangular prismoid defining a three-dimensional body and including a first sheet section folded over thereby exposing a portion of a second sheet section underlying the first sheet section, the first sheet section and the exposed portion of the second sheet section together defining a face of the three-dimensional body; and
a splice member including:
a base having a first side attached with respect to an exposed portion of the face, and a second side opposite the first side; and
a connector having a first portion attached to the first sheet section and a second reusable portion removably attached to at least a portion of the second side of the base.

26. The stock material unit of claim 25 , wherein:
the first sheet section is defined by a plurality of slanted folds and has a generally triangular shape.

27. The stock material unit of claim 25 , wherein the first sheet section is repositionable such that the second portion of the connector is exposed to face outwardly relative to the three-dimensional body to permit contact and attachment to another stock material unit.

28. The stock material unit of claim 27 , wherein the second portion of the connector protrudes transversely outward from the first sheet section.

29. A stock material unit for a dunnage conversion machine, the stock material unit comprising:
a continuous sheet of material defining a three-dimensional body and including:
an underlying sheet section; and
an overlying sheet section connected to the underlying sheet section by a first fold and disposed on the underlying sheet section, wherein the overlying sheet section has a first distance in the transverse direction of the three dimensional body that is less than a se
