Abstract

A rolled sheet-material supply handling-system that comprises a drawing device that can be configured to draw sheet material from a supply station and a stabilizer at the supply station. The stabilizer can define a generally tubular roll-receiving space in which a roll of the sheet material can be received and can have a support surface that can define an axial opening leading from the roll-receiving space to receive the sheet material drawn therefrom by the drawing device. The support surface can be sufficiently extensive to stabilize the outer layer of a roll against collapsing when the remainder of the roll has been extracted from the axial opening.

First claim

What is claimed is:

1. A rolled sheet-material supply handling-system, comprising:
a drawing device configured to draw paper sheet material from a supply station; and
a stabilizer at the supply station defining a generally tubular roll-receiving space in which a roll of the paper sheet material is receivable, the stabilizer having a support surface that defines an axial opening leading from the roll-receiving space to receive the sheet material drawn therefrom by the drawing device, wherein the support surface is configured to be sufficiently extensive about a circumference of the roll in order to stabilize an outer layer of a roll of dunnage paper against collapsing under its own weight when the remainder of the roll has been pulled axially from a center of the roll and extracted from the axial opening, and wherein the stabilizer comprises a support wall that includes the support surface and two opposed ends at opposite circumferential sides of the support surface, the ends being movable with respect to each other.

2. The supply handling-system of claim 1 , wherein the support surface is configured to compress against the outer layer of the roll sufficiently gently to prevent collapsing of the roll when the remainder of the roll has been extracted from the axial opening, and without causing significant deformation of the roll.

3. The supply handling system of claim 1 , wherein the stabilizer is oriented generally upright, such that the axial opening is at the top of the stabilizer.

4. The supply handling system of claim 1 , wherein the support surface is disposed to support at least three points disposed in a coverage angle of more than half of roll-receiving space circumference to support the outer layer of the roll against collapsing.

5. The supply handling system of claim 4 , wherein the support surface is substantially continuous over the circumferential coverage angle.

6. The supply handling system of claim 1 , wherein the support surface is resiliently biased into the roll-receiving space to press on the outer layer of the roll.

7. The supply handling system of claim 1 , further comprising a roll received in the roll-receiving space.

8. The supply handling system of claim 7 , wherein:
the roll-receiving space is substantially cylindrical; and
the support surface is radially biased to a circumference smaller than the roll.

9. The supply handling system of claim 1 , wherein the ends are resiliently movable with respect to each other.

10. The supply handling system of claim 9 , wherein the support wall is flexible to allow the ends to move with respect to each other.

11. The supply handling system of claim 1 , wherein the opposed ends are hinged with respect to each other to move with respect to each other.

12. The supply handling system of claim 1 , wherein the support wall is tubular with an open axial portion between the opposed ends.

13. The supply handling system of claim 1 , wherein the support surface is biased inwardly into the roll receiving space sufficiently gently to press against the outer surface of the roll to support the outer layer of the roll against collapsing when the remainder of the roll has been extracted, and without causing significant deformation of the roll.

14. The supply handling system of claim 1 , wherein the support surface has an axial height sufficient to hold a plurality of rolls stacked on each other in the roll-receiving space.

15. The supply handling system of claim 14 , further comprising the plurality of rolls stacked coaxially in the roll receiving space and daisy chained to each other, the outer surface of a preceding one of the stacked rolls that is daisy chained to a subsequent one of the stacked rolls being in supported contact with the support surface.

16. The supply handling system of claim 1 , further comprising a preceding and a subsequent second roll, the preceding roll received in the stabilizer, and an outer end of the preceding roll daisy chained to an inner end of the subsequent roll, the stabilizer supporting the outer layer of the preceding roll against collapsing when the remainder of the roll has been extracted.

17. The supply handling system of claim 16 , wherein the subsequent roll is received in the stabilizer.

18. The supply handling system of claim 17 , wherein the rolls are coreless.

19. The supply handling system of claim 1 , further comprising an adhesive strip adhering an inner end of one of the rolls to an outer end of a preceding one of the rolls.

20. The supply handling system of claim 1 , wherein the stabilizer comprises a plurality of stabilizer units aligned coaxially with respect to each other, and each stabilizer unit is openable separately and independently from each other.

21. The supply handling system of claim 1 , further comprising a converting station configured to convert the roll into low-density dunnage.

22. The supply handling system of claim 21 , wherein the converting station includes the drawing device.

23. The supply handling system of claim 22 , wherein the converting station includes a rotating drum configured for pulling and crushing the sheet material for converting the sheet material.

24. The supply handling-system of claim 1 , wherein support surface is a cylindrical wall that defines the tubular space.

25. The supply handling-system of claim 24 , wherein the support surface disposed substantially continuously along the wall.

26. The supply handling-system of claim 1 , wherein the support surface extensively contacts at least about 60% of the circumference of the outer layer of the roll.

27. The supply handling-system of claim 1 , wherein the support surface extends about the cylindrical space from a first perimeter end to a second perimeter end, the first and second perimeter ends spaced from one another to define an opening having an arc length that is at least about 20% of the circumference of the cylindrical space.

28. The rolled sheet-material supply handling-system of claim 1 , wherein the support surface is arcuate and configured to be continuously extensive over a coverage angle of at least 40% of the perimeter of the roll.

29. A dunnage apparatus, comprising:
a converting station comprising:
a drawing device configured to draw paper sheet material from a supply station;

and
a converter having a rotating drum configured for pulling and crushing the sheet material for converting the sheet material into dunnage; and

an arcuate stabilizer at the supply station defining a tubular roll-receiving space in which a roll of the paper sheet material is receivable, and having a cylindrical support surface that defines the tubular roll-receiving space and an axial opening leading from the roll-receiving space to receive the sheet material drawn therefrom by the drawing device, wherein the cylindrical support surface is configured to be sufficiently extensive about a circumference of the roll in order to stabilize an outer layer of a roll of dunnage paper against collapsing under its own weight when the remainder of the roll has been extracted from the axial opening, and wherein the stabilizer comprises a support wall that includes the cylindrical support surface and two opposed ends at opposite circumferential sides of the support surface, the ends being movable with respect to each other.
