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 one or more material sheets that form a three-dimensional body and a strap assembly wrapped about the three-dimensional body. The strap assembly includes a base sheet that defines a first face of the strap assembly, a reinforcement member secured to the base sheet and extending along at least a portion of a length thereof, and an adhesive securing a first end of the strap assembly to an opposite, second end of the strap assembly to retain the dunnage in the stock material unit configuration.

First claim

What is claimed is:

1. A stock material unit for a dunnage conversion machine, the stock material unit comprising:
one or more material sheets that form a three-dimensional body; and
a strap wrapped about the three-dimensional body, the strap including:
a base sheet that defines a first face of the strap assembly; and
a reinforcement member that is sufficiently strong to carry the weight of the three-dimensional body and that is affixed onto the base sheet;

wherein the base sheet is sufficiently wider than, and is associated with and affixed to, the reinforcement member to distribute the weight of the three-dimensional body carried by the reinforcement member over the width of the base sheet to prevent or reduce damage to the three-dimensional body by the reinforcement member; and
wherein a first end of the strap is secured to an opposite, second end of the strap with sufficient strength so that the reinforcement member can carry the weight of the three-dimensional body to retain the dunnage in the stock material unit configuration; and
wherein the reinforcing member is substantially continuously secured to the base sheet by an adhesive.

2. The stock material unit of claim 1 , wherein the one or more material sheets define a fanfold stack.

3. The stock material unit of claim 2 , wherein the at least one fanfold stack is formed from a continuous sheet that includes a plurality of folds that define opposing faces that are folded along the continuous sheet.

4. The stock material unit of claim 3 , a single material sheet forms the three-dimensional body.

5. The stock material unit of claim 2 , wherein the one or more sheets define peripheral faces of the three-dimensional body, and the strap assembly is in contact with four of the peripheral faces of the fanfold stack.

6. The stock material unit of claim 1 , wherein the strap assembly includes a laminate sheet bonded to the base sheet, such that the laminate sheet is disposed between the reinforcement member and the base sheet.

7. The stock material unit of claim 1 , wherein the strap includes a first portion defining the first end and having a first width, a second portion defining the second end and having a second width, and a third portion located therebetween and having a third width that is smaller than the first width and the second width.

8. The stock material unit of claim 7 , wherein the third width is at least 50% smaller than the first width or the second width.

9. The stock material unit of claim 7 , wherein the third portion spans across a peripheral face of the three-dimensional body.

10. The stock material unit of claim 7 , wherein the third portion is sized to provide a handle region that facilitates gripping thereof to lift the three-dimensional body thereby.

11. The stock material unit of claim 1 , wherein the reinforcement member is concealed between the three-dimensional body and the base sheet.

12. The stock material unit of claim 1 , further comprising another strap that includes:
another base sheet that defines a first face of the another strap; and
another reinforcement member that is sufficiently strong to carry the weight of the three-dimensional body and that is affixed onto the base sheet, wherein the base sheet is sufficiently wider than, and is associated with and affixed to, the reinforcement member to distribute the weight of the three-dimensional body carried by the reinforcement member over the width of the base sheet to prevent or reduce damage to the three-dimensional body by the reinforcement member;
wherein a first end of the another strap is secured to an opposite, second end of the another strap with sufficient strength so that the reinforcement member can carry the weight of the three-dimensional body to retain the dunnage in the stock material unit configuration, the strap and the another strap being spaced from each other.

13. The stock material unit of claim 12 , wherein the center of gravity of the three-dimensional body is located between the strap and the another strap.

14. The stock material unit of claim 13 , wherein the strap and the another strap are spaced from the center of gravity of the three-dimensional body.

15. The stock material unit of claim 1 , wherein the base sheet and the reinforcement member are substantially the same length.

16. The stock material unit of claim 1 , further comprising an adhesive securing the first end of the strap to the second end of the strap with sufficient strength so that the reinforcement member can carry the weight of the three-dimensional body.

17. The stock material unit of claim 1 , wherein the reinforcement member comprises a fiber reinforced tape.

18. The stock material unit of claim 1 , wherein the reinforcement member extends along at least a portion of the base sheet.

19. The stock material unit of claim 1 , wherein the strap is sufficiently narrower than the width of the three-dimensional body to expose most of the three-dimensional body.

20. 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
a plurality of strap assemblies wrapped about the three-dimensional body, each of the plurality of strap assemblies including:
a base sheet that defines a first face of the strap assembly,
a reinforcement member that is sufficiently strong to carry the weight of the three-dimensional body and that is affixed onto the base sheet, wherein the base sheet configured to and being sufficiently wider than the reinforcement member to distribute the weight of the three-dimensional body carried by the reinforcement member over the width of the base sheet to prevent or reduce damage to the three-dimensional body by the reinforcement member, and
an adhesive securing a first end of the strap assembly to an opposite, second end of the strap assembly with sufficient strength so that the reinforcement member can carry the weight of the three-dimensional body to retain the dunnage in the unit configuration.

21. A stock material unit for a dunnage conversion machine, the stock material unit comprising:
a continuous sheet of material defining a three-dimensional body, wherein the continuous sheet of material includes 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 plurality of strap assemblies wrapped about the three-dimensional body, each of which is sufficiently strong to carry the weight of the three dimensional body.

22. The stock material unit of claim 21 , wherein the plurality of strap assemblies includes at least a first strap assembly at a first location and a second strap assembly at a second location, and the tapered sheet section is located between the first strap assembly and the second strap assembly.

23. The stock material unit of claim 21 , wherein the continuous sheet material is at least partially folded to define a fanfold.

24. The stock material unit of claim 21 , wherein the plurality of strap assemblies includes:
a base sheet that defines a first face of the strap assembly; and
a reinforcement member that is sufficiently strong to carry the weight of the three-dimensional body and that is affixed onto the base sheet.

25. The stock material unit of claim 24 , wherein the base sheet configured to and being sufficiently wider than the reinforcement member to di
