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.

Dunnage conversion machine and method

A machine for converting a sheet stock material into a dunnage product includes a conversion assembly for converting sheet stock material into a dunnage product as the sheet stock material travels along a path from an upstream end of the conversion assembly to a downstream end of the conversion assembly. The machine further includes a transversely extending guide over which the stock material passes for guided entry into the upstream end of the conversion assembly. The guide is rotatable such that the transverse extent of the guide can be moved between a plurality of relatively rotated orientations to guide the sheet stock material from different sides of the conversion assembly.

Void-fill dunnage conversion machine, stock material support, and method

A dunnage conversion machine () converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism () that advances a sheet stock material therethrough and a connecting mechanism () downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

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.

An improved packaging system () includes a packaging line that guides containers in a downstream direction, a sensor () that can identify a dimension of a container on the packaging line, a dunnage dispenser () on the packaging line downstream of the sensor to dispense dunnage to a void volume in a container, and a container closer () downstream of the dunnage dispenser () to close containers on the packaging line downstream of the dunnage dispenser. The container closer () includes an adjustable member (), and is in communication with the sensor to () adjust the adjustable member () 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.

A method of converting a supply of sheet stock into a relatively less dense dunnage product, including the following steps of (i) providing a stack of fan-folded sheet material having fold lines parallel to a width dimension; and (ii) drawing sheet stock material from the stack in a direction parallel to the width dimension.

Reduced footprint dunnage conversion system and method

A method of loading a stack of sheet stock material for use by a dunnage conversion machine, includes the following steps: (i) providing first and second stacks, the second stack being protected by a carrier having a central portion and longitudinally-spaced extensions that bound a central portion, the extensions and the central portion being joined along a weakened area defining a tear line, the central portion and the longitudinally-spaced extensions forming a planar bottom panel and a planar side panel, each panel extending substantially the length of the stack, and at a right angle to each other about a fold line over a bottom and an adjacent side of the stack, and one or more bale ties longitudinally inwardly of the tear lines holding the carrier to the stack; (ii) removing the extensions from the carrier; (iii) setting the second stack on top of the first stack; and (iv) removing the bale ties and the carrier, whereby an adhesive bonds the top page of the first stack to the bottom page of the second stack.
