ABSTRACT:
A flexible, cushioning dunnage product producible on a converter mechanism from a roll of sheet-like stock material, such as biodegradable paper. As the stock material is pulled off the roll by the converter, the edges of the stock material are rolled inwardly to form pillow-like portions which are urged by the converter mechanism laterally inwardly with respect to one another into confronting abutting relation, with the pillow-like portions being then connected together along their engaged abutting sides by in the preferred embodiment, transversely extending coined sections extending transversely of the product and defining a generally central connecting portion running in a direction lengthwise of the product. The lateral, spaced pillow-like portions possess considerable resiliency and thickness as compared to the coined central connecting portion, and perforations are provided in the connecting portion to aid the overlapped coined sections in preventing opening up or separation of the connecting portion, and thus such perforations aid in maintaining the pad-like form of the product for packaging or packing.
