  • Patent number: 7794382
    Abstract: A motor-free dunnage conversion system for converting a sheet stock material into a relatively less dense dunnage includes a container having a wall with an opening therethrough, a supply of sheet stock material within the container, and a forming member. The forming member has converging sidewalls that define a passage alignable with the opening in the wall. The forming member is a converging chute having a relatively larger inlet spaced from the outlet, which is relatively smaller than the inlet. The forming member functions to crumple the sheet stock material as a packer draws the sheet stock material through the forming member to form a crumpled strip of dunnage. The forming member has a dimension that is larger than a corresponding dimension of the opening to keep the forming member from escaping the container as the packer pulls the stock material through the forming member.
