Abstract
A dunnage conversion machine includes a bunching assembly that randomly crumples at least two plies of sheet stock material into modified plies having a relatively thicker three-dimensional shape, and a feeding assembly that advances and connects together longitudinally-extending portions of the modified plies to form a dunnage strip. A diverter minimizes overlap of and encourages separation of lateral edges of the modified plies from one another, and a severing assembly severs distinct dunnage products from the strip. An exemplary resultant dunnage product includes two or more plies of crumpled sheet material interconnected along a longitudinally-extending portion having interconnected overlapped portions of each of the plies and a longitudinally-extending line of connection. Each ply may extend laterally outwardly along randomly crumpled edge portions having a crumpled lateral width greater than a lateral width of the longitudinally-extending portion, the edge portions extending from the line of connection to opposed, laterally-extending free edges.
