Appl. No.:

17/432051

Rob A.H. PLUIJMEN - Landgraaf, NL

International Classification:

B31D 5/00

Abstract:

A cushioning conversion machine converts a sheet stock material into a relatively lower-density cushioning dunnage product. An exemplary sheet stock material includes two sheets that each overlap a common side of another sheet and are connected to respective lateral edges of the other sheet. The conversion machine includes a forming assembly having a former for shaping and randomly crumpling the sheet material, a set of adjustable guide members to guide the crumpled sheet material to a feeding assembly downstream of the forming assembly, and a severing assembly downstream of the feeding assembly that separates discrete lengths of cushioning. The severing assembly includes a window frame passage that guides the crumpled sheet material to an outlet during operation of the feeding assembly and constrains the crumpled sheet stock material during operation of the severing assembly.

International Classification:

B31D 5/00

Abstract:

A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to cause lateral edges of the sheet material to roll towards one another, forming a tubular shape. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect together the overlapping lateral edge portions of the sheet material forming the tab.

International Classification:

B31D 5/00

Abstract:

A dunnage conversion machine includes (i) a pair of gripping rollers configured to rotate at a first rotational speed to advance a slit-sheet material in a downstream direction; (ii) a pair of expansion rollers configured to rotate at a second rotational speed, faster than the first rotational speed, creating a stretching force on the slit-sheet material and further advancing the slit-sheet material, causing expansion of the slit-sheet material to a fully expanded state; and (iii) a pair of relaxation rollers configured to rotate at a third rotational speed, slower than the second rotational speed, reducing the stretching force and further advancing the slit-sheet material, allowing the slit-sheet material to relax to a partially expanded state. The pair of relaxation rollers (iii) also are configured to capture the slit-sheet material in the partially expanded state between a top cover sheet and a bottom cover sheet to form a dunnage pad.

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.

International Classification:

B31D 5/00
B31D 1/00

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.

- Concord Township OH, US
Dennis J. Wagner - Painesville OH, US

International Classification:

B31D 5/00

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.

International Classification:

B31D 5/00

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.
