Abstract

A method of loading a stack of sheet stock material for use by a dunnage conversion machine, includes the following steps: (i) providing first and second stacks, the second stack being protected by a carrier having a central portion and longitudinally-spaced extensions that bound a central portion, the extensions and the central portion being joined along a weakened area defining a tear line, the central portion and the longitudinally-spaced extensions forming a planar bottom panel and a planar side panel, each panel extending substantially the length of the stack, and at a right angle to each other about a fold line over a bottom and an adjacent side of the stack, and one or more bale ties longitudinally inwardly of the tear lines holding the carrier to the stack; (ii) removing the extensions from the carrier; (iii) setting the second stack on top of the first stack; and (iv) removing the bale ties and the carrier, whereby an adhesive bonds the top page of the first stack to the bottom page of the second stack.

First claim

We claim:

1. A bundle of sheet stock material for a dunnage conversion machine, comprising:
a rectangular stack of fan-folded sheet material having a height, a width, and a length, and
a carrier having a central portion and longitudinally-spaced extensions that bound the central portion, the extensions and the central portion being joined along a weakened area defining a tear line, the central portion and the longitudinally-spaced extensions forming a planar bottom panel and a planar side panel, the bottom panel and the side panel being separated by a longitudinally-extending fold line, each panel extending substantially the length of the stack and at a right angle to each other over a bottom and an adjacent side of the stack to protect edges along the length of the stack, where the central portion terminates short of a longitudinally-extending edge of the stack to form a window in the bottom panel that exposes a portion of the bottom of the stack.

2. The bundle as set forth in claim 1 , where both the extensions and the central portion extend across the fold line.

3. The bundle as set forth in claim 1 , comprising one or more bale ties extending around the carrier and the stack to secure the carrier to the stack, the bale ties positioned longitudinally inwardly of the tear lines.

4. The bundle as set forth in claim 1 , comprising an adhesive on at least one of a top page and a bottom page of the stack.

5. The bundle as set forth in claim 4 , comprising a release liner covering the adhesive layer until ready for use.

6. The bundle as set forth in claim 1 , where the carrier has an L-shape cross-section.

7. The bundle as set forth in claim 1 , where the carrier includes cardboard.

8. The bundle as set forth in claim 1 , where the sheet material includes paper.
