摘要： 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.
