  • Patent number: 7361241
    Abstract: In order to produce a nonwoven fabric having elastomeric properties spun filaments (1), consisting preferably (but not essentially) of cellulose material such as cellulose acetate or solvent spun rayon, not in yarn formats, are corrugated or crimped in an overfeed process, as in stuffer box (6), into stabilized three dimensional batts. A proportion of filaments (3) of a thermal memory material, such as modified polyester, in a stretched format are included. The resulting batt is then subjected to controlled hydroentangling and a controlled heat treatment to yield three dimensional nonwoven fabrics with elastomeric properties due to contraction of the stretched filaments. Elastomeric memory material activated to shrink by ultrasonic treatment may be used in place of thermal memory material. The elastomeric properties can be adjusted to suit end-use requirements and applications are envisaged in the medical and hygiene areas.

  • Patent number: 7354495
    Abstract: A composite pressure vessel includes an endcap with first and second layers. The first layer is a thermoplastic layer and the second layer is a thermoplastic and glass fiber composite layer. A method for making the vessel includes placing commingled thermoplastic and glass fibers in a heated mold to melt the thermoplastic. The molten thermoplastic and the glass fibers are molded into the endcap shape. An outer surface of the pressure vessel is finished in accordance with another aspect of the invention. A pressurizable bladder with an inwardly facing surface is deflated. The outer surface of the vessel is heated to soften the thermoplastic. The pressure vessel is positioned in the bladder so that the inwardly facing surface of the bladder is adjacent to an outer surface of the pressure vessel. The bladder is pressurized to move the bladder inwardly into contact with the adjacent surfaces to each other.

  • Patent number: 7347911
    Abstract: Devices and methods for inflating and sealing packaging pillows from a material web are shown for consistently producing high-quality packaging pillows. A web of material is advanced past an inflation nozzle, inflated with gas, and sealed closed by a sealing element. The temperature of the sealing element is monitored using a thermocouple connection and automatically adjusted using a closed-loop system. A sealing clamp parallel to the sealing element maintains two sheets of the web in contact through the sealing step. The inflation nozzle is provided with two inflation outlets: a first outlet inserting gas longitudinally into the web of material, and a second outlet inserting gas laterally into the material. Gas input is controlled with the use of relief valves to maintain pillow quality at all stages of production.

  • Patent number: 7338574
    Abstract: A multilayer composite has a generally adhesion resistant, protective layer and an adjacent second polymeric film. The composition of the protective layer includes a fluoropolymer and the second polymeric film is a polymer free of fluoropolymer. The size of the protective layer facing the second polymeric layer is rendered bondable to the non-fluoropolymer of the second polymeric layer prior to assembling the layers in the composite. The composite is well adapted to being produced in a vertical coating tower. The tower utilizes a carrier web onto which the fluoropolymer layer and second polymeric layer are deposited from respective casting films. Mirror image composites can be formed simultaneously on opposite sides of the carrier web.

  • Patent number: 7335273
    Abstract: A method of making mutually-reinforced elastic strand/film composites and laminates in which film breakage, strand breakage, and strand alignment problems are minimized or avoided. The method includes casting an elastomeric adhesive film onto a chill roll, extruding elastic strands onto the film while the film is on a chill roll, and stretching the film and strand composite. The stretched composite may be laminated between two facing sheets. Additionally, tension in the composite may be controlled through film composition, strand composition, add-on rate, stretching the composite, and combinations of any of these approaches.
