Abstract
A manually-operated dunnage conversion apparatus includes a housing with an outlet opening, a supply of slit sheet stock material supported within the housing for dispensing from the outlet opening, and a pair of opposed expansion members rotatably coupled to the housing for rotation about respective, parallel expansion axes between the supply and the outlet opening. The expansion members are biased towards each other via a biasing member to provide a gripping force on sheet stock material fed therebetween to apply friction to the sheet stock material that causes the sheet stock material to expand in length and thickness as an operator pulls the sheet stock material from the outlet opening in the housing. With the possible exception of the biasing member, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.
