Abstract
A cushioning dunnage product produceable from a mechanism which is of relatively compact nature utilizing a roll of sheet-like stock material, such as paper. As the stock is pulled off the roll, the edges are rolled inwardly in a longitudinally convergent chute, into generally superimposed condition. Pusher means urges the sheet-like stock material laterally toward a confronting surface of the chute. Then the inwardly rolled stock is passed into a crumpler section where mechanism 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 is adapted to coact 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.
