Abstract
A dunnage conversion apparatus for dispensing a cushioning wrap material from a roll of expandable slit sheet material is described. The roll of expandable slit sheet material includes an expandable slit sheet material in an unexpanded state. The expandable slit sheet material is pulled from the roll of expandable slit sheet material and expanded to a pre-expanded state and an expanded state. To expand the expandable slit sheet material and form the cushioning wrap material, a stretching force is applied to the expandable slit sheet material in a stretching direction as it is pulled from the roll of expandable slit sheet material. Accordingly, the dunnage conversion apparatus includes a tensioning device for assisting in the application of such stretching force.
