ABSTRACT:
A cushioning conversion machine includes a plurality of laterally spaced apart upstream assemblies which advance the sheet stock material with a transversely reciprocating twisting motion and at least one downstream assembly that retards the advance of the stock material. Additionally, the upstream assemblies feed the sheet stock material at a feed rate greater than the feed rate at which the downstream assembly passes the sheet stock material. The downstream assembly thereby cooperates with the upstream assemblies to crumple the stock material and impart loft thereto, and as a further result, the crumpled stock material includes a regular arrangement of folds preferably forming a herringbone pattern.
