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: An improved expandable slit-sheet stock material is configured to aid in temporarily restricting opening of a plurality of slits of the slit-sheet stock material, such as during winding of the unexpanded stock material or during expansion of the stock material. Each slit of the plurality of slits includes one or more un-slit reinforcement portions, such as reinforcement ties, extending fully between opposite longitudinal sides of the slit, and disposed between opposed transverse endpoints of the slit. The reinforcement ties minimize or prevent tearing of the stock material during the winding or expansion. A dunnage conversion system for expanding the slit-sheet stock material includes an expander having a pair of opposed rollers. The rollers engage the stock material to effect breaking of the un-slit reinforcement portions and expansion of the slit-sheet stock material.

Abstract: A dunnage conversion machine (36) 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 (40) that advances a sheet stock material therethrough and a connecting mechanism (42) 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.

Abstract: A manually-operated dunnage conversion apparatus includes a housing, a support mounted in the housing and configured to support a supply of sheet material for dispensing from the dunnage conversion apparatus, and one or both of (a) a guide member mounted in the housing downstream of the support and providing a resilient surface across which the sheet material may be drawn to restrict tearing of the sheet material as it is drawn from the dunnage conversion apparatus, and (b) a tensioning assembly mounted in the housing and configured to apply a compressive force between opposite axial sides of the housing to control the force necessary to dispense the supply of sheet material. Except for the tensioning assembly, 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 dunnage conversion machine converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material. The conversion machine includes a conversion assembly that draws the sheet stock material therethrough and randomly crumples at least a portion of the sheet stock material. Before severing a discrete dunnage product of a desired length from the substantially continuous length of sheet stock material, the conversion assembly temporarily advances the sheet stock material therethrough while minimizing or eliminating the random crumpling of the sheet stock material in a reduced-crumpling zone, and then cuts the sheet stock material in the reduced-cutting zone to reduce or eliminate the production of scrap shards of sheet stock material.

Abstract: 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.
