Abstract
A cushioning conversion machine for converting sheet-like stock material, such as a paper in multi-ply form, into cut sections of cushioning product is provided. The machine includes a stock supply assembly, a forming assembly, a pulling/connecting assembly and a cutting assembly, all of which are mounted on a machine frame. The machine frame includes a base plate having an upstream end and a downstream end, a first end plate extending generally perpendicular from the upstream end of the base plate and a second end plate extending generally perpendicular from the downstream end of the base plate. The frame base plate and the two frame end plates together form a "C" shaped structure. The stock supply assembly is mounted on the first frame end plate, the forming assembly is mounted on an intermediate portion of the frame base plate, the pulling/connecting assembly is mounted on an upstream side of the second end plate, and the cutting assembly is mounted on the downstream side of the second end plate. The machine may also include a post-cutting constraining assembly for circumferentially constraining the cut sections of the cushioning dunnage product and/or a pivot cover on one of th…
