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.
1-3. (canceled)
A system as set forth in claim 14, wherein the supply includes a fan-folded stack of sheet stock material.
A system as set forth in claim 14, wherein the supply includes a roll of sheet stock material having a longitudinal axis aligned with the opening.
A system as set forth in claim 14, wherein the supply of sheet stock material includes one or more plies of kraft paper.
7-9. (canceled)
A system as set forth in claim 21, wherein the container has multiple accordion-folded pleats in side walls thereof that allow the volume of the container to be expanded.
A system as set forth in claim 21, wherein the container has an outer portion and an inner portion telescopically movable relative to one another for movement between a compact shipping configuration and an extended converting configuration.
A system as set forth in claim 21, wherein the container has a mechanism that can be used to limit the extent to which the outlet can move from the converting position as sheet stock material is pulled through the outlet.
A system as set forth in claim 21, comprising a supply of sheet stock material contained within the container.
A system as set forth in claim 21, wherein the outlet is defined by a forming member having a relatively larger inlet that is spaced from the relatively smaller outlet.
A system as set forth in claim 21, wherein the forming member is removably attached to an open side of the container
A method of converting sheet stock material to a relatively less dense dunnage product, comprising the steps of reconfiguring a container from a shipping configuration to a converting configuration, and when the container is in the converting configuration manually pulling the sheet stock material from a supply of sheet stock material in the container and through an outlet in the container whereby the stock material is crumpled and permanently deformed to form a relatively less dense strip of dunnage.
(canceled)
A motor-free dunnage conversion system for converting sheet stock material into a relatively less dense dunnage product, comprising a container sized to receive a supply of sheet stock material within the container, the container defining an outlet through which sheet stock material can be drawn to form a relatively less dense strip of dunnage, the container having a shipping configuration and a converting configuration where the outlet is movable between a shipping position in the shipping configuration and a converting position in the converting configuration that is removed from the shipping position.
