Abstract
A cushioning dunnage producing mechanism and method wherein the mechanism utilizes one or more webs of sheet-like stock material, with the stock material being adapted to be disposed by the mechanism in generally superimposed relation and then fed into a crumpler section of tubular-like construction, to radially compress the sheet-like material into a pad-like dunnage product. The lateral edges of the stock material are caused to be rolled inwardly into generally spiral-like form, prior to passage of the stock material into the crumpler section, by a forming frame of generally triangular-like shape both in plan and in side elevation, with the nose of the forming frame being disposed closely adjacent the entranceway to the crumpler section. Meshed spur gears coacting with the crumpler section, coin or stitch the confronting portions of the rolled edges of stock material together, to hold the produced dunnage product in a pad-like configuration. The forming frame mechanism is operable to cause the central coined or stitched section of the pad-like product to be as thin as possible, while urging the stock material into the lateral pillow-like portions of the product, thereby providing greater resiliency to the pad-like product and one of lesser density.
