摘要： A forming section for a twin fabric papermaking machine, wherein after stock impingement, the two fabrics carry and sandwich the stock. A plurality of spaced apart drainage shoes, selectively provided to either or both of the fabrics, provides continuous support in the machine direction for the respective fabric in sliding contact, and each drainage shoe deflects the fabrics by a selected angle of wrap comprising an angular displacement between the leading edge and the trailing edge of the drainage shoe. At least one of the drainage shoes is secured to a drainage box and is provided with a plurality of drainage openings extending from the fabric contacting surface through to the machine side surface of the shoe. The arrangements of the invention provide improved drainage and formation of the paper web.

摘要： A valve ( 100 ) for a vacuum drainage system includes a valve body ( 112 ) having an interior chamber operatively connectable to a suction device and through an outlet ( 110 ) to a vacuum source. A movable member ( 105 ) having an aperture ( 107 ) is secured within the chamber and movable through points between closed and open positions to adjust the open area of the aperture and the fluid flow through the outlet. The aperture is configured such that during adjustment to increase the effective operational area of the aperture, a rate of change of th effective operational area increases non- linearly in relation to a linear increase in the distance of travel, while providing advantageous and more controllable linear adjustment of the applied vacuum. The aperture can have a trilateral shape including at least one curved side, or comprise a plurality of sub - apertures, and the movable member can comprise a rotary sleeve.
摘要翻译：用于真空排水系统的阀门（100）包括具有可操作地连接到抽吸装置并通过出口（110）到真空源的内部室的阀体（112）。具有孔径（107）的可移动部件（105）固定在腔室内并可在闭合位置和打开位置之间的点移动，以调节孔的开口面积和通过出口的流体流动。孔被配置为使得在调节期间增加孔径的有效操作面积时，有效操作面积的变化率相对于行进距离的线性增加而非线性增加，同时提供有利且更可控的线性调整应用真空度。孔可以具有包括至少一个弯曲侧的三边形状，或者包括多个子孔，并且可动构件可以包括旋转套筒。
