摘要： In a twin wire former a headbox injects stock onto a forming wire with which a second forming wire is brought into gradual engagement. A forming shoe directs the two wires along a path of increasing curvature, above which water is drained by adjustable auto slices. The two wires with the web therebetween then follow an oscillating S-shaped path between seven S-rolls and are directed upwardly through three individually loaded press rolls with increasing pressure to about four hundred and fifty pounds per linear inch at the last wet press. Drainage pans collect water from the upper surface of the twin wires and water thrown off the upper press rolls. The press rolls are individually pneumatically pivotable to increase nip pressure, and collectively pivotable to open all the nips. Next a high pressure dry nip can increase the fiber content of the web to thirty-five percent fiber.

摘要： An apparatus for stabilizing a low-strength sheet having a width and a top surface and moving in a first direction at a rate sufficient to entrain air. The apparatus includes an airfoil adapted to extend along the top surface of the sheet. The airfoil, in turn, includes: a bottom surface adapted to extend along a portion of the top surface of the sheet; a first surface extending a first distance from the bottom surface at a first juncture; a second surface extending a second distance from the bottom surface at a second juncture; and a top surface extending from the first surface at a third juncture to the second surface at a fourth juncture. The first distance in general is less than the second distance. In addition, the apparatus is oriented in a manner such that the portion of the apparatus which first encounters the entrained air is the first surface of the airfoil, and the first and bottom surfaces of the airfoil form an acute angle such that the first surface directs a substantial portion of the entrained air away from the sheet. The apparatus may include a forebody, a passageway, and/or a deflector.

摘要： The instant device is a forming board position control system. A forming board fitted with the instant invention is positioned at various distances from and with virtually perfect constant parallelarity to the lie of the frontal plane of a headbox in apposition to the forming board. A computer controlled motor causes a parallelwise positioned pair of worm gear jacks mounted to the board, to move the board longitudinally to and fro through a distance from the frontal plane of the headbox as is determined with reference to manually manipulated computerized settings until the system stops perforce of a signal to such effect received by a controller computer as the result of interaction as between a magnet affixed to the base of one of two mounting plates to which the board is also mounted and a transducer closely positioned thereto and connected directly to the computer.

摘要： A machine side layer weave design for use in woven composite fabrics, particularly papermakers forming fabrics having differing weave designs on each planar surface is provided. The composite fabric is comprised of two sets of weft yarns interwoven with at least one system of warp yarns. A first set of weft yarns is interwoven with the at least one system of warp yarns to form the paper side layer, while the second set of weft yarns is interwoven with the at least one system of warp yarns to form the machine side layer. In each repeat of the machine side layer weave design, at least 50% of the warp yarns pass under two adjacent weft yarns on the machine side of the fabric to form a double warp knuckle, and each double warp knuckle is bounded on either side by a single warp knuckle formed on each of the first and second weft passed under by the double warp knuckle. Further, in each repeat of the weave, each weft yarn is passed under by two adjacent warp yarns to form two adjacent single warp knuckles. In one embodiment, all of the warp yarns form double warp knuckles; in an alternate embodiment, 50% of the warp yarns form double warp knuckles. The knuckles are evenly distributed across the machine side surface so as to minimize any propensity for guiding. The machine side layer weave design of the invention is suitable for use in any composite fabric and is effective in minimizing or eliminating fabric edge curl, a problem common in fabrics of this type.
摘要翻译：提供了用于织造复合织物的机器侧层编织设计，特别是在每个平面上形成具有不同编织设计的织物的造纸机。复合织物由两套与至少一种经纱系交织的纬纱组成。第一组纬纱与至少一种经纱系统交织以形成纸侧层，而第二组纬纱与至少一种经纱系统交织以形成机器侧层。在机器侧层编织设计的每个重复中，至少50％的经纱在织物的机器侧上的两个相邻纬纱下通过以形成双经节，并且每个双经节在任一侧由在双经向下通过的第一纬纱和第二纬纱的每一根上形成单个经节。此外，在织造的每次重复中，每条纬纱都被两根相邻的经纱通过，以形成两个相邻的单个经节。在一个实施例中，所有经纱形成双经节; 在一个替代实施例中，50％的经纱形成双经节。指关节均匀分布在机器侧表面，以便最小化任何引导倾向。本发明的机器侧层编织设计适用于任何复合织物，并且有效地最小化或消除织物边缘卷曲，这种类型的织物中常见的问题。

摘要： In a twin-wire former in a paper machine, an operation of a hybrid former mode and that of a gap former mode are conducted, and papers of quality conforming to the kind of papers can be made in a wide range of basis weight with regard to multiple kinds of papers.In the twin-wire former, a forming roll, which guides a top wire so that it can approach to a bottom wire to pinch the stock of paper and run approximately horizontally, is made adjustable in an up and down direction.Upper surfaces of blades of a forming board and a forming shoe provided inside a loop of the bottom wire, are upwardly convex so that dewatering can be effected mainly downward.

摘要： An adjustable blade apparatus including an operative surface which cooperates with a forming wire of a forming section. The apparatus includes a stationary support which extends in a cross machine direction relative to the forming wire. The support defines a guide rail having a front and a back end. The front end is disposed at a different elevation relative to the back end. The arrangement is such that the guide rail slopes in a cross machine direction. A blade defines the operative surface and the blade cooperates with the guide rail such that the blade is adjustably supported by the support. The arrangement is such that relative cross machine directional movement between the guide rail and the blade adjust the elevation of the operative surface relative to the wire.
