摘要： A fabric support element for a papermaking machine has improved fluid drainage means, comprising openings which can include flow-through vents. The element can comprise an impingement shoe for a forming section of a papermaking machine. The openings can be defined by a plurality of laminar segments, at least some of which define a paper side surface of the element, and which segments can be spaced apart by additional laminar segments or other spacing means. Laminar segments for use in the element, a method of constructing the element, and a papermaking machine, or a forming section thereof, including the element are also provided.

摘要： An adjustable resilient blade support for use in the forming section of a papermaking machine. The blade support is adjustable, both to allow the attached blade to be moved from a position where it is out of contact to a position where it is pressed into contact with the adjacent forming fabric, and to permit adjustment of the blade orientation relative to the surface of the forming fabric. The blade support is also resilient, and thus allows the blade to respond to transient localized changes in the path of the forming fabric with which it is in contact. The adjustable resilient blade support of this invention is thus of use in an open surface forming section, and also is of use in forming sections in which two forming fabrics are used.
摘要翻译：一种用于造纸机的成型部分的可调弹性叶片支撑件。叶片支撑件是可调节的，以允许附接的叶片从其脱离接触的位置移动到其被压靠与相邻的成形织物接触的位置，并且允许相对于叶片的方向调整叶片方位成形织物的表面。叶片支撑件也是弹性的，因此允许叶片响应与其接触的成形织物的路径中的瞬时局部变化。因此，本发明的可调节的弹性叶片支撑件可用于开放的表面形成部分中，并且也用于形成其中使用两个成形织物的部分。

摘要： A press felt for use in the press section of a papermaking machine is provided. The press felt includes a base fabric layer and at least one layer of a staple fiber batt material connected thereto. The press felt has a paper side surface (PS) which when in operation is in contact with a paper web conveyed thereon and a machine side surface (MS) which contacts various press section components. At least one scrim that includes a regenerated cellulosic fiber having a dtex from at least about 1.1 to about 44 is located between two batt layers or one batt layer and the base fabric. Felts including the scrim of regenerated cellulosic fibers provide improved dewatering when compared to similarly constructed felts which lack this regenerated cellulosic fiber batt material.

摘要： An integrated cutter for preparing the edges of a fabric for seaming includes a hooked needle which oscillates vertically in a guide bushing located close to the plane of the fabric between a retracted position where the head of the needle is not exposed and an extended position in which the needle penetrates the fabric. The needle head is shaped so that when it moves upwardly it pushes between a pair of yarns in one direction until the hook is above a yarn in the other direction. The needle hook includes a transverse groove shaped so that when it moves downwardly it captures this yarn. The needle is a close fit within the guide bushing, to ensure cooperation between cutting edges at the lateral ends of the transverse groove and at the periphery of the hole at the top end of the guide bushing around the needle, so that a short length of the trapped yarn is severed cleanly as the cooperating cutting edges at each side of the hook and at the top end of the guide bushing pass each other when the needle moves downwardly. A carrier moves the device laterally a preset distance, and the cycle is repeated to cut another section of yarn. Since the integrated cutter of this invention does not rely on friction within the fabric to hold the yarn as it is cut, distortion of the adjacent area of the fabric is minimised.
摘要翻译：用于制备用于缝合的织物的边缘的整体切割器包括钩针，其在靠近织物平面的引导衬套中垂直摆动，该引导衬套位于未暴露针头的缩回位置和延伸位置之间，针穿透织物。针头的形状使得当其向上移动时，它在一个方向上推动一对纱线之间，直到钩在另一个方向上在纱线上方。针钩包括横向槽，其形状使得当其向下移动时捕获该纱线。针头紧密配合在引导衬套内，以确保在横向槽的横向端部处的切割边缘和引导衬套的顶部周围的针孔周围的配合，使得短的被捕获的纱线被清洁地切断，因为当针向下移动时，钩的每一侧的合作切削刃和引导衬套的顶端彼此通过。托架将设备横向移动预设的距离，重复循环以切割另一部分纱线。由于本发明的一体式切割机不依赖织物内的摩擦力来保持纱线在切割时，使织物相邻区域的变形最小化。

摘要： A multilayer papermaking fabric having interwoven machine direction (MD) and cross-machine direction (CMD) yarns, the CMD yarns defining at least upper and lower CMD yarn subsets which are interwoven with the MD yarns in a repeat pattern such that the MD yarns have substantially more interweavings with the upper CMD yarn subset than with the lower CMD yarn subset. The lower subset CMD yarns define machine side floats under at least seven MD yarns and each MD yarn interweaves with only two lower subset CMD yarns in a given repeat.

摘要： A fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the equipment or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

摘要： A composite forming fabric for a papermaking machine woven according to a repeating fabric weave pattern is provided. The fabric includes a paper side (PS) layer having a PS surface, with the PS layer including PS warps and PS wefts interwoven in a first repeating pattern, and a machine side (MS) layer having a MS surface, with the MS layer including interwoven MS warps and MS wefts. A plurality of pairs of binder weft yarns each including first and second binder weft yarns that are interwoven with the PS warps and the MS warps to bind the PS and MS layers together in the composite forming fabric. In each pattern repeat of the fabric weave pattern at least three of the MS warps pass under each MS weft, where said at least three of the MS warps are co-located adjacent to one another with a further one of the MS warps separating a first of the at least three warps from the others of said at least three warps, and each of the MS warps interlaces with at least two non-adjacent ones of the MS wefts.

摘要： A seamless press felt is provided having inner and outer base fabric layers, which can be woven or non-woven, having an MD length and CD width, each including at least a first array of MD oriented yarns and being formed as a continuous unbroken tube structure. An elastic intermediate yarn assembly with parallel and regularly spaced CD yarns, each bonded to an elastic carrier material, is formed as a continuous unbroken tube structure, and is “socked” between the inner and outer base fabric layers. The elastic intermediate yarn assembly has an MD length that is from 1% to 10% less than the MD length of the press felt prior to assembly and is elastically stretched during assembly between the inner and outer base fabric layers. At least one batt layer needled through the inner and outer base fabric layers and the elastic intermediate yarn assembly to fornt he press felt.

摘要： A film for conveying in an industrial process, industrial fabrics made from the film, and methods of manufacture. The film has a plurality of protrusions separated by land areas. Each protrusion comprises a top member having opposing lateral edges and is supported by opposed compression resistant first and second end walls, which with at least one of the lateral edges define an aperture extending through the film to provide a flow path. The base edge of each end wall has a configuration selected from at least one of the base edge being convexly curved away from the protrusion body; and each end wall extending below at least a part of each of the first and second lateral edges and being connected to each of the first and second lateral edges. The film structure provides physical properties equivalent to a woven fabric, with improved strength, stability and compression resistance.
