A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to cause lateral edges of the sheet material to roll towards one another, forming a tubular shape. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect together the overlapping lateral edge portions of the sheet material forming the tab.
A dunnage product made from a sheet stock material formed into a tube having at least three planar sides giving the tube a polygonal cross-sectional shape, where the planar sides of the tube are crumpled and adjacent planar sides are joined at respective vertices of the polygonal cross-sectional shape, and where lateral edge portions adjacent lateral edges of the sheet stock material are connected together to form a ridge disposed along one of the vertices,
A dunnage product made from a sheet stock material formed into a tube, wherein the tube is formed by:
