Dunnage conversion machine and method

A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

A molded packing material and a method of making the molded packing material. The molded packing material includes a plurality of molded fiber cushioning elements. The molded packing may also include a matrix comprising cellulosic fibers bonding the plurality of molded fiber cushioning elements to each other. The plurality of molded fiber cushioning elements and matrix form a mass that has been molded into a shape having exterior surfaces and an interior with some of the plurality of molded fiber cushioning elements being on the exterior surfaces of the mass and the remainder of the plurality of molded fiber cushioning elements being in the interior of the mass. The molded packing material may also include a fiber shell having a cavity formed therein with the plurality of molded fiber cushioning elements located in the cavity.
