  • 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: 7347809
    Abstract: A system for creating and dispensing cushioning dunnage is small and permits flexible installation configuration options for a single or multiple packing stations. A compact apparatus of the system is capable of being pivotally mounted as a unit on a stand and includes a motor and a material feeding arrangement driven by the motor for pulling material from a supply roll of the material supported on a stand of the system, and feeding it through the apparatus. A plurality of material shaping members upstream of the feeding arrangement shape the material in the apparatus to convert it into a continuous strip of cushioning product.

  • Patent number: 7335151
    Abstract: A method, apparatus and system for making cushioning product, and a roll tensioner therefor apply frictional resistance to the periphery of a roll of material to be converted into cushioning product with at least one roll support member which supports the roll in addition to applying frictional resistance to rotation. Efficient operation is attained automatically in that the frictional resistance applied and also the pulling profile exerted on the material during unwinding of the roll are changed as a function of weight and/or other characteristics of the roll of material to be converted into cushioning product.

  • Patent number: 6503182
    Abstract: A system for creating and dispensing cushioning dunnage is small and permits flexible installation configuration options for a single or for multiple packing stations. A compact apparatus of the system is capable of being pivotally mounted as a unit on a stand and includes a motor and a material feeding arrangement driven by the motor for pulling material from a supply roll of the material supported on a stand of the system, and feeding it through the apparatus. A plurality of material shaping members upstream of the feeding arrangement shape the material in the apparatus to convert it into a continuous strip of cushioning product. A perforator driven by the motor perforates the material at spaced locations along the length of the material to allow an operator to manually rip a desired length of cushioning product from the material being dispensed from the apparatus.

  • Patent number: 6471154
    Abstract: An automatic roll tensioner for a material dispensing system enables a material, e.g., paper or plastic, to be unwound from a roll of the material by pulling the material from the roll while maintaining tension on the material when pulling suddenly stops. The roll of material is positioned in the roll tensioner such that it can be rotated about a longitudinal axis of the roll by pulling the material from the roll to unwind material from the roll. A mechanism actuated by the weight of the roll of material applies frictional resistance to the rotation of the roll at a plurality of circumferentially spaced locations on the periphery of the roll. An apparatus for converting sheets of paper into cushioning dunnage advantageously employs the automatic roll tensioner.
