Abstract
A cushioning conversion machine for converting stock material into a continuous strip of a cushioning product. The machine includes a stock-preparing assembly which prepares the stock material; a stock-shaping assembly which shapes the prepared stock material into a continuous strip having a pillow-like portion and at least one tab portion projecting therefrom; and a tab-connecting assembly which connects the tab portion of the continuous strip whereby the pillow-like portion will maintain its pillow-like geometry.
Claims27
A method for converting sheet stock material into a cushioning product, said method comprising the steps of:
- providing a sheet stock material having at least one shell ply and at least one stuffing ply;
- and
- converting the sheet stock material into a continuous strip of dunnage having a pillow-shaped portion and at least one tab portion;
- wherein said converting step includes converting the sheet stock material into a strip of dunnage having a pair of proximate portions and a pair of distal portions of a flat section of the at least one shell ply;
- wherein said converting step includes using a series of flat walls to fold the pair of distal portions over the pair of proximate portions to form the tab portion;
- and
- wherein said converting step includes converting the sheet stock material into a strip of dunnage having a pillow shaped portion which includes both the at least one shell ply and the at least one stuffing ply.
A cushioning conversion machine for converting sheet stock material into a cushioning product, the machine comprising:
- a frame;
- conversion assemblies mounted to the frame which convert the stock material into a continuous strip of dunnage having a pillow-shaped portion and a tab portion;
- a stock supply assembly, positioned upstream of the conversion assemblies, which supplies stock material to the conversion assemblies, the stock material having at least one shell ply and at least one stuffing ply;
- and
- wherein the conversion assemblies include a folding device having a series of flat walls which coordinate to fold a pair of distal portions over a pair of proximate portions of a flat section of the at least one shell ply to form the tab portion;
- and
- wherein the pillow-shaped portion is formed by both the at least one shell ply and the at least one stuffing ply.
