  • Patent number: 6723208
    Abstract: A papermaker's fabric is manufactured by spirally winding a laminated structure in a plurality of turns. The laminated structure has a bottom layer and a top layer, both of which are strips having a common width. The bottom layer and the top layer are laminated to one another in a transversely offset manner, so that an unlaminated portion of the bottom layer is along one lateral edge of the laminated structure and an unlaminated portion of the top layer is along the other lateral edge. When the laminated structure is spirally wound, the unlaminated portion of the top layer in one turn overlies the unlaminated portion of the bottom layer in an adjacent turn. These are joined to one another to form the papermaker's fabric from the spirally wound structure.

  • Patent number: 6713413
    Abstract: A buffing or polishing material has a nonwoven fleece layer and a backing layer that adds strength and dimensional stability to the material. The nonwoven fleece layer is a needled blend of natural fibers and synthetic fibers having a uniform density and working surface, resulting in a better polishing or finishing consistency. The material can withstand high heat levels and can be worked quickly, resulting in a more efficient polishing or finishing operation. The buff material can be converted into any preferred shape or tool, such as an endless belt, disc, flapwheel, or spiral band.

    Abstract: Composite structures and methods are taught relating to temperature stabilizing saddle pads, horse blankets, saddle girths, saddle seat cushions, and saddles for protection and increased performance of horses and/or riders, among other similar products. The invention provides for products that stabilize the temperature of the horse and/or the rider by absorbing heat generated by the body of the horse and/or rider when the temperature exceeds a preset temperature appropriate for the product. In this process heat energy is absorbed through phase change, resulting in a constant temperature as long as there is material that has not changed phase.

  • Publication number: 20030092337
    Abstract: Composites made from at least two plies are described, where one of the outer layers is a layer comprising glass fibers, and in particular is a staple glass fiber nonwoven. The layers have been bonded to one another by needling, and the extent of this needling is such that some of the fibers of the organic nonwoven emerge from the surface of the glass fiber sheet. The composite is then provided with a binder by using a rotating roll for single-side application to the glass fiber surface. The composites are particularly suitable for producing bituminized prefabricated roofing and waterproofing sheets, and as backings for coatings, e.g. PVC coatings.

  • Publication number: 20030008584
    Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

The first and second base fabrics are attached to one another by at least one layer of staple fiber batt entangled therethrough such that they are offset with respect to one another in a lengthwise direction when so joined. As a consequence, seaming loops at one widthwise edge of the first base fabric coincide with a non-seam region of the second base fabric, and seaming loops at one widthwise edge of the second base fabric coincide with a non-seam region of the first base fabric. These coincident non-seam regions have additional flow-resistant material included so that when the on-machine-seamable papermakers' fabric is joined into endless form by closing both seams, it may, in the vicinities of the seams, have permeabilities to air and water substantially identical to the remainder of the fabric body thereof.

  • Patent number: 6179965
    Abstract: Hollow synthetic monofilament yarns are used in the construction of a base fabric for a papermakers wet felt. The synthetic hollow monofilament yarns have selected interior void, compressibility and resiliency characteristics and are interwoven with other yarns to form a woven base fabric with the hollow monofilament yarns predominating, on at least the paper carrying side of the base fabric. The weaving and finishing of the base fabric results in the hollow monofilament yarns retaining a substantially unflattened cross-section. Accordingly, substantially unflattened portions of the hollow monofilament yarns predominate the paper carrying side of the base fabric thereby providing a cushioning surface which is compressibly resilient to assist in the dewatering of the aqueous paper web as it is transported through a press nip during the manufacture of the paper.

  • Patent number: 6140260
    Abstract: A felt for use in a papermaking machine includes a woven base fabric and a batt layer for supporting the paper web. A flow control layer is interposed between the base fabric and the fibrous batt layer, to impede rewetting of the paper web as the paper web exits a press nip of the papermaking machine. The flow control layer is formed of a porous hydrophobic material. Pressure exerted by the press nip forces water from the paper web through the batt layer and the flow control layer into the base fabric. When the pressure is relieved, the hydrophobic properties of the flow control layer impede back-flow of water to the batt layer and thence to the paper web, thereby impeding rewetting of the web. The flow control layer is preferably formed of a spunbonded filamentary nylon material which is non-circular in cross-section, such as tri-lobed/triangular, and which may be treated with an hydrophobic chemical composition to enhance hydrophobic properties.
