  • Patent number: 7361132
    Abstract: A novel cushioning conversion machine and method for converting sheet stock material into a novel cushioning product and for producing discrete sections or pads of desired length, without the need for a cutting assembly, thereby enabling the construction of a less expensive, smaller and less complex machine. The machine and method are characterized by a weakening device for perforating a sheet stock material of one or more plies along tear lines so that as a strip of cushioning is formed from the stock material, discrete sections or pads of desired length may be detachable along the tear lines. The stock material includes material which is biodegradable, recyclable and composed of a renewable resource, such as kraft paper.

  • Patent number: 7258657
    Abstract: A cushioning conversion machine and related methodology characterized by one or more features including, inter alia, a feeding/connecting assembly which enables an operator to easily vary a characteristic, for example the density, of the cushioning product; a feeding/connecting assembly wherein input and/or output wheels or rollers thereof are made at least in part of an elastomeric or other friction enhancing material, which reduces the cost and complexity of the input and output rollers; a manual reversing mechanism that is useful, for example, for clearing paper jams; a modular arrangement of a forming assembly and feeding/connecting assembly in separate units that may be positioned remotely from one another, as may be desired for more efficient utilization of floor space; a turner bar which enables alternative positioning a stock supply roll; and a volume expanding arrangement cooperative with the feeding/connecting assembly for reducing the density of the cushioning product and increasing product yield.

  • Patent number: 6974407
    Abstract: A conversion machine and related method for making a dunnage product by converting a sheet-like stock material of at least one ply into a dunnage product is characterized by a manual reversing mechanism that is useful, for example, for clearing paper jams. The conversion machine includes a housing through which the stock material passes along a path, and an assembly that advances the stock material from a source thereof along the path, crumples the stock material, and maintains the shape of the crumpled stock material to produce a strip of dunnage. This assembly includes at least one rotatable member rotatable in a first direction for engaging and advancing the stock material, a feed motor for driving a driven rotatable member in the first direction, and a crank connected to the rotatable member for enabling rotation of the driven rotatable member in a second direction opposite the first direction.

  • Patent number: 6540652
    Abstract: A cushioning conversion machine (20) for converting sheet-like stock material (22) into a three-dimensional cushioning product (P) including a device (400; 400′; 500; 600; 600′; 700) which controls the width of the strip and which may be selectively adjusted to change the width of the strip. By selectively setting the device (400, 400′, 500; 600; 600′; 700), a cushioning product of a desired width may be produced. For more sophisticated packaging needs, the stock material may be converted into a first portion of a certain width, the device adjusted, and then the stock material may be converted into a second portion of a different width whereby the cushioning product will have continuous portions of different widths.

  • Patent number: 6387029
    Abstract: Cushioning conversion stitching/coining members each include a plurality of radially outwardly extending projections that meshingly engage during rotation. One stitching member includes a recess and the other stitching member includes cutting edges received in the recess to cut a row of slits in the overlapped portions of the stock material to form at least one row of tabs for interlocking the overlapped portions of the stock material. The cutting edges are radially positioned between adjacent projections of the second stitching member and circumferentially spans less than the circumferential space between adjacent projections. Additionally or alternatively, the projections are shaped so that there is exaggerated backlash between meshing projections.

  • Patent number: 6033353
    Abstract: A novel stock roll support assembly and loading method for a cushioning conversion machine that produces dunnage product from sheet stock material supplied as a roll provides for easier loading of the stock roll onto a roll support at the upstream end of the cushioning conversion machine in certain situations, such as where the machine is located against a wall or over (or under) a conveyor, etc. The stock roll support assembly is connected to a main frame of the machine for rotatably supporting a roll of sheet stock material. The stock roll support assembly includes a stock roll support mounted to the main frame for swinging movement between an operating position and a loading position. In the operating position, the stock roll support is operative to support the stock roll adjacent the main frame, and in the loading position, the stock roll support is swung away from the main frame to facilitate loading of a stock roll thereon.
