Method of operating a dunnage conversion machine
View Patent ↗A supply of sheet stock material for use in a cushioning conversion machine is disclosed. The supply of stock material includes at least one ply of sheet stock material rolled or folded into a compact configuration such as a roll of wound stock material or a stack of fan-folded stock material. The ply has disposed on a leading or trailing end thereof, a pressure sensitive adhesive layer and a removable release liner covering the pressure sensitive adhesive layer. When a supply of sheet stock material is almost spent, a succeeding supply of stock material may be spliced to the almost spent supply by removing the release liner to expose the adhesive and then applying the leading or trailing end, having the adhesive thereon, to a trailing end of the almost spent supply of stock material or leading end of the succeeding supply of stock material.
1. A method of converting sheet stock material into a dunnage product, comprising the steps of:
operating a conversion machine to produce a dunnage product from a supply of multi-ply sheet stock material until the supply of sheet stock material is almost spent;
removing a release liner to expose a pressure sensitive adhesive on a leading end of a ply of a succeeding supply of sheet stock material or on the trailing end of a ply of the almost spent supply of stock material;
applying the leading end of a ply of the succeeding supply of stock material to the trailing end of a ply of the almost spent supply of stock material such that the pressure sensitive adhesive bonds the ends together; and
operating the conversion machine to produce additional dunnage product;
wherein the step of removing the release liner and the step of applying the leading end to the trailing end is repeated for each ply.
2. A method as set forth in claim 1 , wherein the step of removing the release liner includes removing the leading end of a ply of the succeeding supply of stock material and the pressure sensitive adhesive thereon from an adjacent layer of the succeeding supply of stock material or removing the trailing end of a ply of the almost spent supply of stock material and the pressure sensitive adhesive thereon from an adjacent layer of the almost spent supply of stock material.
3. A method as set forth in claim 1 , wherein the step of removing the release liner includes removing a paper strip release liner from the leading end of a ply of the succeeding supply of stock material or from the trailing end of a ply of the almost spent supply of stock material.
4. A method as set forth in claim 1 , wherein the step of applying includes placing the leading end of a ply of the succeeding supply of stock material over the trailing end of a ply of the almost spent supply of stock material.
5. A method as set forth in claim 1 , wherein the step of applying includes placing the trailing end of a ply of the almost spent supply of stock material over the leading end of a ply of the succeeding supply of stock material.
6. A method of converting sheet stock material into a dunnage product, comprising the steps of:
operating a cushioning conversion machine to produce a dunnage product from a supply of multi-ply sheet stock material until the supply of sheet stock material is almost spent;
removing a release liner to expose a pressure sensitive adhesive layer on a carrier;
applying the carrier to the trailing end of a ply of the almost spent supply of stock material and the leading end of a ply of the succeeding supply of stock material such that the adhesive layer bonds the carrier to the trailing end of the almost spent supply of stock material and the leading end of the succeeding supply of stock material; and
operating the cushioning conversion machine to produce additional dunnage product;
wherein the step of removing the release liner and the step of applying the leading end to the trailing end is repeated for each ply.
7. A method as set forth in claim 6 , wherein the step of removing the release liner includes removing the leading end of a ply of the succeeding supply of stock material and the pressure sensitive adhesive thereon from an adjacent layer of the succeeding supply of stock material or removing the trailing end of a ply of the almost spent supply of stock material and the pressure sensitive adhesive thereon from an adjacent layer of the almost spent supply of stock material.
8. A method as set forth in claim 6 , wherein the step of removing the release liner includes removing a paper strip release liner from the leading end of a ply of the succeeding supply of stock material or from the trailing end of a ply of the almost spent supply of stock material.
9. A method as set forth in claim 6 , wherein the step of applying includes placing the leading end of a ply of the succeeding supply of stock material over the trailing end of a ply of the almost spent supply of stock material.
10. A method as set forth in claim 6 , wherein the step of applying includes placing the trailing end of a ply of the almost spent supply of stock material over the leading end of a ply of the succeeding supply of stock material.
