Cushioning conversion machine and method

A cushioning conversion machine for converting sheet-like material into a relatively low density cushioning dunnage product, comprising a former through which the sheet-like stock material is advanced to form the stock material into a three-dimensional shape, a feed mechanism for advancing the stock material through the former, a blade assembly for cutting the cushioning dunnage product into cut sections, said blade assembly including at least one movable blade for cutting the cushioning dunnage product, and an operator assembly, said operator assembly including a pair of cranks operatively engaging opposite ends of said blade assembly such that rotation of said cranks effects movement of said one movable blade, and a handle having opposite ends each operatively connected to a respective one of said cranks for rotating said cranks upon movement of said handle, wherein at least one end of said handle is adjustable relative to the respective crank whereby said operator assembly can be aligned with said blade assembly, wherein said cranks are secured to respective axially aligned pivot shafts for rotation, said handle has a mount at each end for attachment to a hub on a respective pivot shaft and at least one fastener for securing said mount to said hub, said fastener passing through an aperture in one of said mount and hub, and said aperture being circumferentially elongated relative to the axis of the respective pivot shaft to provide for rotational adjustment of said handle relative to said crank.
