Abstract: A wet web transfer belt for a closed draw papermaking machine is provided with a rough surface to allow easy release of a wet web. The rough surface is obtained easily, and with reliable quality, by forming the web-contacting side of a batt layer from a welded layer of meltable fiber.

Abstract: A shoe press belt for use between a press roll and a shoe for pressing water from a wet sheet, formed with one or more grooves on the surface thereof for draining water, wherein the groove defines a plurality of laterally spaced channels, the channels having outwardly curved side walls and may include a rounded bottom. The shoe press belt has an improved groove configuration which retains water drainage capacity under nip pressure, while at the same time being resistant to crack formation, thereby enabling a satisfactory service life and avoiding the formation of ‘groove-marks’ on the pressed sheet. The press belt is simple in design and thus inexpensive to manufacture.

Abstract: A shoe press belt capable of improving flexibility in bending in the axial direction of and of inhibiting cracks in the belt where it contacts the ends of a shoe has first resin layer formed on a mandrel, a base material layer formed on the outer periphery of the first resin layer, and a second resin layer including the base material layer. The base material layer is a composite layer including an inner layer in which one or more yarn strands are wound spirally on the first resin layer in the circumferential direction, a middle layer in which a yarn strand is arranged on the inner layer generally parallel to the axial direction of the mandrel, and an outer layer in which at least one yarn strand is wound spirally on the middle layer in the circumferential direction in such a way that it does not overlap the yarn of the inner layer and crimps the yarn of the middle layer.

Abstract: A shoe press jacket, wherein a base fabric layer consisting of woven cloth having filament yarn of straight or nearly straight arrangement in at least one of warp and weft is coated with resin from one surface thereof, the thickness of said base fabric layer is filled with said resin and a coated layer is formed on the opposite surface.

Abstract: A shoe press belt for papermaking comprises an endless first resin layer formed on a polished surface of a mandrel; a base fabric layer comprising a woven fabric leaf arranged over the entire outer periphery of the first resin layer, at least one of the sets of intersecting threads of the fabric leaf being high-strength threads extending axially along the mandrel; a bobbin layer comprising high-strength thread circumferentially wound in a spiral on the outer periphery of the base fabric layer; and an endless second resin layer on the outer periphery of the bobbin layer, the second resin layer being in contact with the first layer through the base fabric layer and the bobbin layer. The shoe press belt constructed in this manner exhibits high strength in the machine direction as well as in the cross machine direction.

Abstract: A shoe press belt has both sides coated with a resin layer and one or both layers with side edge portions softer than the middle portion of the resin layer. The hardness of the side edge portions may first decrease stepwise laterally outwardly from the middle portion to a section which overlies the edge of the shoe, and then increase stepwise laterally outwardly to the edge of the belt. A first stepwise reduction in hardness may begin laterally inward of the edge of the wet paper sheet and extend laterally outwardly to the edge of the wet paper sheet, where a second stepwise reduction begins that extends laterally outwardly beyond the edge of the shoe. Laterally outwardly of the second reduction, a stepwise increase in hardness extends to the edge of the belt. Alternatively, each side edge portion may be of a single hardness, less than the hardness of the middle portion, and each side edge portion overlies one of the side edges of the shoe.

Abstract: A shoe press belt for the shoe press of a paper making machine includes first and second resin layers and a base layer. Resin is coated and cured on the polished surface of a cylindrical mandrel to form the first resin layer endlessly. An inner layer of the base layer is formed by spirally winding a relatively narrower belt shaped mesh with warp threads running in the major direction of the belt and weft threads running perpendicular thereto, with the weft threads against the outer surface of the first resin layer, and without overlapping the end edges of the belt-shaped mesh. An outer layer of the base layer is formed by inserting the mandrel, with the first resin layer and the belt-shaped mesh layer applied, into a tubular mesh, and pulling the ends of the tubular mesh apart, so as to reduce its diameter and press it radially against the belt-shaped mesh layer.

Abstract: A paper making felt for use in hot press or press drying paper making processes comprising a base cloth layer and batt fiber layers, with at least the paper-contacting surface layer of the batt fiber layers composed principally of poly(paraphenylene benzoxazole) fiber. The felt exhibits a high degree of resistance to flattening, and consequently its effectiveness in removing water from the paper and its useful life for that purpose are enhanced.

Abstract: The invention provides a heat-resistant felt for hot products which is sufficiently heat-resistant for conveying or placing hot products thereon in manufacturing processes of iron and steel, non-ferrous metal, and ceramics products, and contributes to the improvement of the quality and life of products. A heat-resistant fiber web of a blend or laminate comprising metal fibers and inorganic fibers or a heat-resistant fiber web of a blend or laminate comprising metal fibers or inorganic fibers and heat-resistant organic fibers is needle-punched with or without a heat-resistant ground fabric laminated so as to intermingle.
