  • Patent number: 7479100
    Abstract: A system for creating and dispensing cushioning dunnage includes a plurality of material shaping members to convert a sheet stock material into a continuous strip of cushioning product. The shaping members include a constant-entry roller assembly having at least two tapered rollers supported end to end for rotation about respective ones of first and second axes arranged at an obtuse angle whose aspect faces a circumferential side of the rollers that first engages sheet stock material traveling over the rollers from a supply roll of the material. The tapered rollers present material engaging surfaces on an imaginary material conversion line transverse to the travel direction of the material where the material first engages the rollers for more precise and consistent control of alignment of the stock material. The roller assembly has free ends over which the sheet stock material can be folded to reduce the width of the material traveling over the rollers.

  • Patent number: 7410454
    Abstract: This invention forms a loose fill packing material comprising clean, elongated strips of paper formed from corrugated cardboard having internal fluting formatted to expand in height, improving the ability of the strips to lattice. A vertical slitter divides cardboard into blanks of a predetermined width generally with the grain of corrugation. The blanks are fed into a shredding device that cuts the blanks with a scissor motion across the width of the blank. The strips pass onto a cleated perforated conveyor and into an enclosed suction housing. Inside the suction housing is a vortex box enhancing air flow for cleaning the strips. Strips are centered on the conveyor. The strips move from the conveyor to an angled, vibrating sifter plate into a collector. Strips are sprayed with a liquid material having microbicidal, sanitizing, insect repellant, disinfectant and/or deodorizing properties.

  • Patent number: 7407471
    Abstract: 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.

The stock supply assembly (550) includes a separating device (574) and/or constant-entry device (580) designed to minimize tearing due to excessive tension in the lateral regions of the stock material (22). Additionally or alternatively, the forming assembly (52) includes a shaping member (590) having protrusions in its turning perimeter and/or holding surface to modify the shape of the cushioning product.

  • Patent number: 6699167
    Abstract: A cushioning conversion machine having a novel former around which a sheet material is folded to form an improved cushioning product. The former has longitudinally spaced side surfaces inclined from bottom to top toward a downstream end of the machine. The side surfaces cause the obstruction of the sheet stock material upstream of the side surfaces so that the sheet material crumples in the spaces upstream of the side surfaces, thereby increasing the cushioning properties of pillow portions of the cushioning product. The former also has a centrally located base plate which minimizes crumpling in a central portion of the sheet material so that the folded over portions and the central portion can be connected to maintain more effectively the shape of the pillow portions in the resulting cushioning product. In addition, the former has a guard plate mounted above longitudinally spaced bottom edges extending laterally outwardly from the base plate and upstream from a vertical central plane.
