Abstract:
A dunnage conversion machine includes a forming assembly configured to form a sheet stock material into a strip of dunnage, and a feeding assembly downstream of the forming assembly that is configured to pull the sheet stock material through the forming assembly. The machine also includes a tear assist assembly downstream of the feeding assembly that includes a pinch arm on one side of the path and a stop opposing the pinch arm on an opposite side of the path. The pinch arm is movable between a resting position in which the pinch arm is located on the one side of the path, and a pinching position in which the pinch arm is located in the path to capture the strip of dunnage between the pinch arm and the stop. Reversing the feed assembly while the pinch arm is in the pinching position causes the strip of dunnage to tear.
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.
Abstract:
A conversion assembly for a dunnage conversion machine includes both a downstream pair of rotatable members and an upstream pair of rotatable members upstream of the downstream rotatable members. The downstream rotatable members include a pair of gears, and each gear has a plurality of teeth and is rotatable about a respective axis. The gears are positioned so that the teeth of one gear are sequentially interlaced with the teeth of the other gear as the gears rotate. The upstream rotatable members include a pair of feed wheels, and the gears and the feed wheels define a path for a sheet stock material from between the upstream pair of feed wheels to between the downstream pair of gears. The rate at which the sheet stock material is advanced by the feed wheels is the same as the rate at which the sheet stock material is advanced by the gears.
Abstract:
A bundle of packing material includes at least two strips of packing material folded into a compact configuration. The strips of packing material include a top strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion, and a bottom strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion. The central portion of the top strip overlays the central portion of the bottom strip and the length dimension of the top strip is oriented orthogonal to the length dimension of the bottom strip. The first and second end portions of top strip are folded over the central portions, and the first and second end portions of the bottom strip are folded over the central portions.
Abstract:
A dunnage conversion assembly includes a supply of expandable sheet material and a dunnage conversion apparatus configured to expand the expandable sheet material. The apparatus includes a frame, a supply support mounted to the frame to support a supply of sheet material, and first and second expansion members rotatably mounted to the frame downstream of the supply support to receive the sheet material therebetween. At least one of the first expansion member or the second expansion member is rotatably driven. A drive assembly of the apparatus includes a drive member and a motive device that drives rotation of the drive member to dispense the sheet material from the supply. The drive member is movable between an operating position adjacent the supply support and a disengaged position spaced from the supply support. The drive member in the operating position is biased toward the supply support.
Abstract:
An improved packaging system (10) includes a packaging line that guides containers in a downstream direction, a sensor (12) that can identify a dimension of a container on the packaging line, a dunnage dispenser (14) on the packaging line downstream of the sensor to dispense dunnage to a void volume in a container, and a container closer (16) downstream of the dunnage dispenser (14) to close containers on the packaging line downstream of the dunnage dispenser. The container closer (16) includes an adjustable member (20), and is in communication with the sensor to (12) adjust the adjustable member (20) based on the identified dimension of the container. The system thus includes a way to identify the size of the container before the container reaches the container closer. The container closer can adjust for the container's size before the container arrives, speeding up the container closing operation.

Abstract:
A dunnage conversion machine includes a bunching assembly that randomly crumples at least two plies of sheet stock material into modified plies having a relatively thicker three-dimensional shape, and a feeding assembly that advances and connects together longitudinally-extending portions of the modified plies to form a dunnage strip. A diverter minimizes overlap of and encourages separation of lateral edges of the modified plies from one another, and a severing assembly severs distinct dunnage products from the strip. An exemplary resultant dunnage product includes two or more plies of crumpled sheet material interconnected along a longitudinally-extending portion having interconnected overlapped portions of each of the plies and a longitudinally-extending line of connection. Each ply may extend laterally outwardly along randomly crumpled edge portions having a crumpled lateral width greater than a lateral width of the longitudinally-extending portion, the edge portions extending from the line of connection to opposed, laterally-extending free edges.

Abstract:
A bag forming apparatus for forming a flat bottom of a bag includes a base, opposing sidewalls that extend upright relative to the base, and a top that is operably coupled to an upper portion of each of the sidewalls. The top has an intermediate pivot axis between the sidewalls that enables the top to pivot about the pivot axis between a collapsed state and an expanded state. In the collapsed state, the upper portions of the respective sidewalls are closer together and the top extends upright relative to the base to form a tip for insertion into an opening of the bag. In the expanded state, the upper portions of the respective sidewalls are spaced further apart and the top extends horizontally relative to the base to form a platform for forming the flat bottom of the bag.
