Abstract: A supply (22) of sheet stock material (24, 34) for a dunnage conversion machine (26) that is readily spliced to another supply includes (a) one or more plies of sheet material (24, 34) having (i) multiple longitudinally-extending sections, including a center section (42) bounded by lateral sections (40), where the lateral sections (40) are folded over a common face of the center section (42) along longitudinal fold lines (44) at lateral edges of the folded sheet material, and (ii) a leading end (60) and a trailing end (62) at respective longitudinally-opposite ends of the sheet material, where the lateral sections (40) are separated from the center section (42) adjacent the leading end (60) and adjacent the trailing end (62) along respective lines of separation; and (b) a splicing adhesive (76) applied to the sheet material adjacent the leading end (60) or the trailing end (62) on both the center section (42) and each of the lateral WO 2020/092578 A1 sections (40) to facilitate splicing each section to respective sections of two supplies.

Abstract: A dunnage conversion machine is provided for converting a sheet stock material into a relatively lower density dunnage product as it moves downstream through the conversion machine. The conversion machine includes a forming assembly configured to inwardly gather sheet stock material, and a feeding assembly downstream of the forming assembly. The forming assembly includes a converging chute with an inlet and a relatively smaller outlet downstream of the inlet, the converging chute being aligned along a converging axis. The feeding assembly has a pair of rotatable members rotatable about respective parallel axes of rotation. The rotatable members are arranged to feed sheet stock material from the forming assembly downstream of the feeding assembly, the rotating members defining a feed axis perpendicular to a line connecting and perpendicular to the axes of rotation. The conversion machine is characterized by the converging axis being transverse rather than aligned with the feed axis.
