A supply (22) of sheet stock material (24, 34) for a dunnage conversion machine (26) that is readily spliced to another supply includes (a) one or more plies of sheet material (24, 34) having (i) multiple longitudinally-extending sections, including a center section (42) bounded by lateral sections (40), where the lateral sections (40) are folded over a common face of the center section (42) along longitudinal fold lines (44) at lateral edges of the folded sheet material, and (ii) a leading end (60) and a trailing end (62) at respective longitudinally-opposite ends of the sheet material, where the lateral sections (40) are separated from the center section (42) adjacent the leading end (60) and adjacent the trailing end (62) along respective lines of separation; and (b) a splicing adhesive (76) applied to the sheet material adjacent the leading end (60) or the trailing end (62) on both the center section (42) and each of the lateral WO 2020/092578 A1 sections (40) to facilitate splicing each section to respective sections of two supplies.

An arrangement for producing embossed cushioning material from an initially flat material comprises an embossing device for providing a plurality of embossed protrusions to the material, an undulating device comprising undulated forming spaces which creates undulations in the initially flat material prior to the undulated material being provided to the embossing device, and a conveying means for conveying the initially flat material along a transport path in a continuous process through the undulated forming spaces. It is that suggested that the undulating device, seen in the direction of the transport path, comprises at least two stages each comprising an undulated forming space, the undulated forming space of a downstream stage differing in number and/or height of undulations from the undulated forming space of an upstream stage.

A dunnage conversion machine is provided for converting a sheet stock material into a relatively lower density dunnage product as it moves downstream through the conversion machine. The conversion machine includes a forming assembly configured to inwardly gather sheet stock material, and a feeding assembly downstream of the forming assembly. The forming assembly includes a converging chute with an inlet and a relatively smaller outlet downstream of the inlet, the converging chute being aligned along a converging axis. The feeding assembly has a pair of rotatable members rotatable about respective parallel axes of rotation. The rotatable members are arranged to feed sheet stock material from the forming assembly downstream of the feeding assembly, the rotating members defining a feed axis perpendicular to a line connecting and perpendicular to the axes of rotation. The conversion machine is characterized by the converging axis being transverse rather than aligned with the feed axis.

A method of making a dunnage product includes the following steps: (a) converting a sheet stock material into a lower density strip of dunnage having a width and a height that is less than the width; and (b) cutting the strip of dunnage to form a discrete dunnage product of a desired length by cutting across less than the width of the strip of dunnage to maintain a connection between the strip of dunnage and the discrete dunnage product. The connection between respective dunnage products in a string of connected dunnage products keeps the dunnage products together, in the order in which they were produced, and helps to ensure that the dunnage products do not shingle and can assist in feeding the dunnage products to a packing station.

A stock material unit for a dunnage conversion machine is provided herein. The stock material includes a first strip of sheet material at least partially defining a three-dimensional configuration. The strip of sheet material includes a first end and a second end opposite the first end. The stock material includes a splice member mounted with respect to the sheet material in a first position. The splice member includes a connector that has a bonding member configured to stick to the first end. The connector is releasable from the first position and repositionable to a second position in which it is affixed to the first end by a connecting portion. In the second position, the connecting portion has an exposed area for affixing to a second end of a second continuous sheet of the material to daisy chain the first and second strips of sheet material.

A packaging cushion includes a first liner and a second liner opposite one another and each defining an inner surface. A transverse liner axis extends normal to the inner surfaces. The packaging cushion includes a mesh bonded to and disposed between the first and second liners. The mesh has a top mesh surface and an opposed bottom mesh surface. The mesh defines a plurality of nodes and a plurality of legs interconnecting the plurality of nodes. Each of the plurality of nodes defines 1) a top node surface defined by the top mesh surface, 2) a bottom node surface defined by the bottom mesh surface, and 3) a transverse node axis extending substantially normal to the top and bottom node surfaces. The transverse node axes of at least some of the plurality of nodes are each oriented at an oblique angle relative to the transverse liner axis.

Methods and structures are provided for a dunnage system to facilitate efficient coupling together of supply units of pre-configured sheet stock material, such as, for example, separate units of fanfold stacks of pre-configured sheet stock material, in a manner of continuous supply with a continuous pocket extending longitudinally between the separate supply units, so that they can interact with an expander of the dunnage system without disruption as one supply unit is depleted and a next supply unit is fed through the dunnage system. Also, various methods, apparatus, and systems are provided to facilitate smooth operation of a dunnage machine of the dunnage system to reduce a tendency of the pre-configured sheet stock material to jam and to increase the tendency of dunnage product generated to reflect a desired shape and stability.

The strip of sheet material includes a first end and a second end opposite the first end. The stock material includes a splice member mounted with respect to the sheet material in a first position.

In the second position, the connecting portion has an exposed area for affixing to a second end of a second continuous sheet of the material to daisy chain the first and second strips of sheet material.

The invention relates to a device for providing a three-dimensional cushioning material for cushioning an void volume in a transport container, comprising a converting apparatus for converting a flat web-like starting material into the three-dimensional cushioning material and a receiving means for receiving at least regions of a stack of the web-like starting material folded in a zigzagging manner. The receiving means has a first lateral contact means for a first stack type, which has a first width (B1), and a second lateral contact means for a second stack type, which has a second width (B2), such that either a stack of the first stack type or a stack of the second stack type can be arranged in the receiving means in a centered manner relative to the same central axis.
