Patent abstract
A stock material (16) for use with a dunnage conversion machine (14) includes at least one ply of sheet material having spaced along the length thereof a plurality of transverse rows (22) of weakened areas (24). The weakened areas (24), which can be formed by perforations, for example, have a reduced strength relative to adjacent portions of the sheet material. Each row (22) of weakened areas (24) has at least one parameter that varies along the row (22). The strength of the stock material at the row (22), in response to a force applied across the row (22), varies across the stock material (16).
