    摘要： An on-machine-seamable industrial fabric includes rings in the seam region. In one principal embodiment, the rings are between the seaming loops at the two ends of the fabric and enclose at least one cross-machine-direction (CD) yarn. As such, the rings strengthen the seam region by involving the CD yarns as a reinforcement. In another principal embodiment, the rings are used instead of a seaming spiral.

    摘要： An anti-rewet press fabric for paper and board machines includes a barrier layer such that during compression in the press nip, the water is forced through the barrier layer, but is prevented from flowing back to the paper web during expansion. The barrier layer comprises a continuous material possessing, for example square, rectangular, tetrahedral, circular or oblong conical inclusions with a smaller opening on the bottom than on the top of the structure. Each of these “funnels” effectively constitutes a one-way valve and creates a vacuum to prevent re-absorption of water by the paper sheet. Under pressure, the structure of the barrier layer allows water to flow into the cones and out of the smaller opening in the bottom. Upon expansion, the smaller opening in the bottom of the structure restricts backward water flow and creates a vacuum on the other side. The vacuum increases water retention in the press fabric and prevents rewetting of the paper sheet. Another embodiment of the invention is described herein, wherein the barrier layer exists as a separate fabric fed through a press section. In this embodiment, the “separate fabric” can just be the “conical inclusion sheet” itself. That is, the sheet itself constitutes an inventive belt having anti-rewet properties.

    摘要翻译： 用于纸张和纸板机的抗再润湿压榨织物包括阻挡层，使得在压榨压区期间的压缩期间，水被迫通过阻挡层，但是在膨胀期间防止水流回纸幅。 阻挡层包括具有例如正方形，矩形，四面体，圆形或长方形的圆锥形夹杂物的连续材料，其底部具有比结构顶部更小的开口。 这些“漏斗”中的每一个有效地构成单向阀并产生真空以防止纸张再吸收水分。 在压力下，阻挡层的结构允许水流入锥体并从底部较小的开口流出。 膨胀后，结构底部的较小开口限制了向后的水流，并在另一侧产生真空。 真空增加压榨织物中的保水性并防止纸张的再润湿。 本文描述了本发明的另一个实施例，其中阻挡层作为通过压榨部分供给的单独织物存在。 在本实施例中，“分开的织物”本身可以是“圆锥形夹杂物片”。 也就是说，片材本身构成具有抗再润湿性能的本发明的带。

    摘要： An actuator having a set of slidable pistons including sliding regions with the sliding regions including at least one wear member supported by a resilient member and a second wear member laterally spaced from the first wear member with a lubrication reservoir located therebetween for maintaining the wear members in lubricated sliding engagement with the cylindrical walls of the housing to limit the need to replace or repair the actuator. In order to provide ingress and egress of fluid from the chambers within the actuator a channel passage extends along the back side of the extension of the piston to permit quick venting of fluid therefrom.

    摘要： An on-machine-seamable industrial fabric comprising rings connected by pintles. In one principal embodiment, the rings are oriented in the machine direction and the pintles extend at an angle, connecting the rings. Such configuration improves the strength of the fabric and provides resistance to needling damage. In another principal embodiment, the rings are oriented in the cross-machine direction and the pintles extend in the machine direction, joining the rings.

    摘要： A press fabric is manufactured by spirally winding a strip in a plurality of non-overlapping abutting turns, and by joining each turn of the strip to that previously wound. The strip is itself a laminated structure having at least two layers attached to one another. The strip is manufactured in considerable lengths for subsequent use in manufacturing press fabrics in any length and width dimension.

    摘要： A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics is disclosed. The structure includes axially and radially elastic hollow members, and relatively inelastic yarns in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

    摘要： A stratified press fabric for the press section of a paper machine includes a base fabric in the form of an endless loop. A first staple fiber batt material is attached to the outer side of the base fabric by needling. A fine fabric covers the first staple fiber batt material, and a second staple fiber batt material is attached to the fine fabric by needling. The fibers making up the second staple fiber material are finer, that is, of smaller diameter or denier, than the fibers making up the first staple fiber material. The fine fabric prevents the coarser fibers of the first staple fiber batt material from being needled therethrough to mix with the finer fibers of the second fiber batt material.
