A cushioning conversion machine and method for converting sheet-like stock material into a cushioning product without the use of a conventional forming device, thereby enabling a substantial reduction in the size of the machine. The machine and method are characterized by the use of a web of flat-folded sheet-like stock material of one or more plies and an expanding device which is operative to open up, or "expand", the flat folded stock material before passage through a crumpling and/or connecting device which also preferably functions to advance the stock material through the machine. The invention also provides a flat folded web of stock supply including at least one ply of sheet-like stock material having portions thereof folded upon themselves along the length of the stock material.
