Abstract
A conversion machine and related method for making a dunnage product by converting a sheet-like stock material of at least one ply into a dunnage product is characterized by a manual reversing mechanism that is useful, for example, for clearing paper jams. The conversion machine includes a housing through which the stock material passes along a path, and an assembly that advances the stock material from a source thereof along the path, crumples the stock material, and maintains the shape of the crumpled stock material to produce a strip of dunnage. This assembly includes at least one rotatable member rotatable in a first direction for engaging and advancing the stock material, a feed motor for driving a driven rotatable member in the first direction, and a crank connected to the rotatable member for enabling rotation of the driven rotatable member in a second direction opposite the first direction.
