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.

Carrier for a bundle of fan folded sheet material to be converted into dunnage

A tabletop converter has a conversion assembly that inwardly gathers and crumples a stock material to form a strip of dunnage. The conversion assembly includes a feeding assembly that moves the stock material and a controller that controls the feeding assembly to operate in both a forward direction and a reverse direction. To automatically separate a discrete dunnage product from the strip, a holder grabs and holds the strip of dunnage at a holding location downstream of the feeding assembly. The feeding assembly then operates in a reverse direction and urges the strip away from the holding location. This causes the strip to separate at or between the holding location and the feeding assembly, leaving a discrete dunnage product ready for use. The converter is mounted to a stand that allows the converter to rotate relative to part of the stand about both a horizontal axis and a vertical axis.

Cutterless dunnage converter and method

A dunnage conversion machine for converting stock material into a dunnage product includes a forming assembly and a pulling assembly. The pulling assembly includes at least two grippers movable together through a transfer region in opposition to one another and cooperative to grip therebetween the dunnage strip for advancing the dunnage strip through the transfer region, and at least one of the grippers including an aperture operative to gather and laterally capture therein the dunnage strip as the grippers move through the transfer region. Also disclosed is a severing assembly including a movable blade and a reciprocating actuator connected to the blade by a motion transmitting assembly that moves the blade through a full severing cycle upon a stroke of the actuator in either direction. Also disclosed is a void fill dunnage product including a three dimensional crumpled strip of dunnage round in cross-section and including at least one ply of sheet material having, in cross-section, a crumpled multi-lobed undulating body, with the lobes thereof extending longitudinally and being dispersed in an irregular pattern.

A dunnage conversion machine () and corresponding method for converting a supply of sheet stock material into a relatively less dense dunnage product includes a conversion assembly () that converts sheet stock material into a dunnage product, and a tension-adjusting assembly () having a sequence of transversely extending members () disposed upstream of the conversion assembly (). The transversely extending members () engage the stock material and help to prevent or to minimize excessive edge tension and/or the tearing associated therewith, while maintaining sufficient tension for proper tracking, especially for the conversion of single ply, lesser quality and/or short fiber paper, and/or otherwise improves or enhances the conversion process. The transversely extending members () are generally aligned end-to-end, and define a path for the stock material from a supply thereof, via a stock supply assembly () to the conversion assembly ().

Dunnage conversion machine and method

An easy load packaging system, and a stand and a dunnage conversion machine therefor are disclosed. The stand includes a base and a pair of upright guide members mounted to the base and supporting at the upper ends thereof a dunnage conversion machine. The guide members define there between a channel for guiding sheet stock material to the dunnage conversion machine. The dunnage conversion machine is pivotable relative to the stand between an operating position and a servicing/loading position whereat access to internal components of the machine is simplified. A stack of sheet stock material is jacketed and/or baled for simplified loading into a packaging system or stand. An adhesive layer on the bottom or top of the stack enables the stack to be easily spliced to another stack.
