  • Publication number: 20080275412
    Abstract: An article, including disposable articles and durable articles, includes one or more shaped thermoplastic members, which can be at least partially impregnated into one or more fibrous substrates forming a composite material of the article having regions of breathability, elasticity, and/or stiffening to provide desired functions of the article. The shaped thermoplastic members have a profiled thickness and/or basis weight providing variation in material properties. A percent variation of the profiled thickness of the thermoplastic member can vary from about 5% to about 95%. A process for manufacturing the composite material of the present invention is also disclosed.

  • Patent number: 5620514
    Abstract: A magnetizable layer can be applied to a flexible backing web by gravure coating at high speeds by independently driving the backing web at a speed that is substantially different from the surface speed of the gravure roll. Especially high coating speeds have been achieved when the gravure roll rotates oppositely to the direction in which the backing web is advancing. In one embodiment, a nip roll presses the backing web against the backup roll, there is a gap between the gravure roll and a backup roll, and an idler roll is positioned downstream of the gap to force the backing web into contact with the gravure roll over a short arc. When that backup roll has a hard surface such as metal, its surface can be machined with precision, and that precision can be maintained in spite of exposure to solvent vapors.

  • Patent number: 5609686
    Abstract: An apparatus continuously smoothes a wet coating of magnetizable particles and binder on a moving flexible web. A first longitudinal end of a flexible film is held in contact with the wet coating on the substrate and is free to drag against the wet coating. The first longitudinal end is deflected toward the substrate along a line extending transversely between the first and second transverse ends. The amount of deflection is adjusted and varied during coating to adjust the radius of curvature of the deflection of the first longitudinal end. A smoothing bar or a cylindrical rod, with or without a sharp edge, can hold the flexible film in position. The deflection and adjustment can be performed by a screw. Alternatively, a cylindrical rod is used by itself.
