摘要： A process and apparatus for improving paper formation on an open surface paper making machine is described. By the use of both a path for the forming fabric which introduces a controlled level of agitation into the stock, and a low level of vacuum in a suction box extending continuously for the forming section, improvements both in paper quality, such as improved wire mark, and in machine operation, such as an improved first pass retention, are obtained.

摘要： A pin seam for use in woven papermaking fabrics, wherein more than 50 % of the warp strands from each of the fabric ends are used to form the pintle retaining loops. The loops formed at one of the opposing fabric ends have an "S" orientation, while the loops formed at the second opposing end have a "Z" orientation, thereby allowing the two sets of pintle retaining loops to interdigitate easily. The resulting seam is strong, easily installed on the papermaking machine and has a reduced propensity to mark the paper web. The invention is particularly applicable to fabrics woven using 3-shed weave patterns or integral multiples thereof.
摘要翻译：用于编织造纸织物的针接缝，其中来自每个织物端部的超过50％的经线被用于形成枢轴保持环。在相对的织物端部中的一个上形成的环具有“S”取向，而在第二相对端形成的环具有“Z”取向，从而允许两组枢轴保持环相互交叉。所得到的接缝牢固，易于安装在造纸机上，并且具有降低标记纸幅的倾向。本发明特别适用于使用3棚编织图案编织的织物或其整数倍。

摘要： A method and apparatus are disclosed whereby the rate of drainage of the stock on a paper making machine can be controlled for the full length of an open surface forming section. A continuous sealed drainage box is used from adjacent the head box slice to the end of the forming section, within which the air pressure can be controlled. In the area adjacent the head box slice drainage is hindered by the use of a positive (above ambient atmospheric) pressure, whilst further along the forming section the pressure is decreased to a negative value (below ambient atmospheric). Improved paper formation and first pass retention are obtained.

摘要： A paper machine dryer fabric includes hollow thermoplastic monofilaments to replace at least a portion of the wefts, also known as cross-machine direction strands. Fabrics including such monofilaments may be either a woven fabric, or a spiral fabric. The deformable nature of the hollow monofilaments decreases the air permeability of the fabric, and in the case of spiral fabrics, improves monofilament retention within the helical coils between the hinge yarns. The hollow monofilaments have a solidity in the range of from about 50 % to about 80 %. A suitable thermoplastic is polyethylene terephthalate. Hollow monofilaments do not have the disadvantages of other deformable yarns, such as spun yarns, multifilament yarns or plied monofilament yarns, each of which tend to hold and entrap within their structure both water and foreign matter.

摘要： An improved papermaker's forming fabric is described in which a 14 or 16 shaft weave design is used. This design uses a construction in which the larger cross direction yarns on the machine side of the fabric float under at least 10 machine direction yarns. The binding points for these large-diameter cross direction yarns lie directly under a four-yarn float of paper side cross direction yarns. Further, the machine direction yarns float over only two adjacent cross direction yarns, at a point substantially halfway between the machine side binding points. This construction permits the use of very large cross direction machine side strands, without compromising the drainage capabilities of the fabric and wire mark propensity. The invention is particulaly useful in fabric designs where extra cross direction floater yarns are included on the paper side of the fabric, in which case the machine side binding points are located under the larger of the paper side cross direction yarns.
摘要翻译：描述了一种改进的造纸织物，其中使用14或16轴编织设计。该设计使用这样的结构，其中在织物的机器侧上的较大的横向纱线在至少10个机器方向的纱线下浮动。这些大直径横向纱线的粘合点直接位于纸侧横向纱线的四纱浮子下面。此外，机器方向纱线在机器侧结合点之间的基本上一半的点上漂浮在仅两个相邻的横向纱线上。这种结构允许使用非常大的横向机器侧线，而不损害织物的排水能力和线标倾向。本发明特别适用于织物设计，其中额外的横向浮动纱线包括在织物的纸面上，在这种情况下，机器侧的结合点位于较大的纸张横向纱线的下方。

摘要： A paper machine dryer fabric in which at least a portion of the component yarns are monofilaments comprised of a copolymer of dimethylolcyclohexane, terephthalic acid, and isophthalic acid, and an effective amount of a hydrolysis stabiliser. The molar ratio of terephthalic acid to isophthalic acid used in preparing the copolymer is about 83:17, and the copolymer has an intrinsic viscosity which is greater than about 0.75 dL/g. The copolymer imparts to the monofilaments an increased resistance to hydrolytic degradation and improved knot properties, in comparison to other known polymers used in dryer fabrics. Low density polyethylene may optionally be added to the copolymer to increase the resistance of the monofilaments to surface contamination and soiling.
摘要翻译：一种造纸机干燥器织物，其中至少一部分纱线是由二羟甲基环己烷，对苯二甲酸和间苯二甲酸的共聚物构成的单丝和有效量的水解稳定剂。在制备共聚物中使用的对苯二甲酸与间苯二甲酸的摩尔比为约83:17，共聚物的特性粘度大于约0.75dL / g。与在干燥织物中使用的其它已知聚合物相比，共聚物赋予单丝增加的抗水解降解性和改善的结特性。可以任选地将低密度聚乙烯加入到共聚物中以增加单丝对表面污染和污染的抵抗力。

摘要翻译：造纸机干燥器织物包括中空热塑性单丝，以替代纬纱的至少一部分，也称为横机线方向线。包括这种单丝的织物可以是机织织物或螺旋织物。中空单丝的可变形性降低了织物的透气性，并且在螺旋织物的情况下，改善了铰链纱线之间的螺旋线圈内的单丝保持力。中空单丝具有在约50％至约80％范围内的坚固性。合适的热塑性塑料是聚对苯二甲酸乙二醇酯。空心单丝不具有其它可变形纱线的缺点，例如短纤纱，复丝纱线或合股单丝纱线，其各自倾向于在其结构内保持并捕获水和异物。

摘要： A dewatering fabric for the press section of a paper making machine is described having improved dewatering characteristics, improved resistance to compaction, and enhanced ability to bridge cavities, such as grooves or holes, in press section rolls. The fabric includes at least two distinct layers of flattened monofilament warp yarns at a high fill factor, and at least one layer of weft yarns. Advantageously, the fabric is constructed to provide long exposed floats of one of the distinct layers of warp yarns on the paper side of the fabric. The fabric may be used alone, with a paper side batt, or with a batt on both sides.
