Abstract
A method of making and using cushioning dunnage material. A cushioning dunnage producing mechanism is disclosed which is of relatively compact nature utilizing a single multi-ply roll of sheet-like stock material, such as paper. As the stock is pulled off the composite roll, the edges are rolled inwardly in a longitudinally convergent chute, into generally superimposed condition. Then the inwardly rolled webs of stock are passed into a crumpler section where mechanism such as meshed gears attach together the confronting portions of the rolled edges of the stock material generally centrally, in a direction lengthwise thereof, to retain the dunnage product in highly compressible, lightweight pad-like form. A transfer vehicle coacts with the dunnage producing mechanism for storing a preselected amount of the pad-like dunnage product on the vehicle, whereupon the vehicle can be moved to a location distant from the dunnage producing mechanism for use at the distant location.
