More Information
Summary:Cushioning conversion stitching/coining members each include a plurality of radially outwardly extending projections that meshingly engage during rotation. One stitching member includes a recess and the other stitching member includes cutting edges received in the recess to cut a row of slits in the overlapped portions of the stock material to form at least one row of tabs for interlocking the overlapped portions of the stock material. The cutting edges are radially positioned between adjacent projections of the second stitching member and circumferentially spans less than the circumferential space between adjacent projections. Additionally or alternatively, the projections are shaped so that there is exaggerated backlash between meshing projections.
