摘要： A testing device for determining the amount of liquid having been doctored through the Fourdrinier fabric or wire at the wet end of a Fourdrinier-type paper machine. Included is a pick-up for insertion beneath the foil blades of the paper machine, having an opening for insertion into the stream of the liquid being doctored from the pulp. A container is connected in liquid communication with the pick-up. A weir is positioned within the container to divide the container into a collection well upstream from the weir and a discharge well downstream from the weir. The container includes a still well positioned in liquid communication with the collection well. A proximity sensor is provided, and positioned with respect to the still well to sense the level of liquid in the still well. A microprocessor controlled display is provided for receiving a signal from the proximity sensor and displaying a flow rate based on the level of the liquid in the still well. The size and shape of the weir opening, and of the pick-up opening, are adjustable to bring the flow rate through the device into a suitable range for purposes of the display.
摘要翻译：一种用于确定在长网造纸机的湿端通过长网织物或线材处理的液体量的测试装置。包括用于插入造纸机的箔片叶片下面的拾取器，其具有用于插入从纸浆中取出的液体流中的开口。容器与拾取器液体连通。堰被定位在容器内，以将容器分成井堰上游的井道和堰下游的排放井。容器包括仍然良好地定位成与收集井液体连通。提供接近传感器并且相对于静止孔定位以感测静止井中的液体的水平。提供微处理器控制的显示器，用于接收来自接近传感器的信号，并且基于静止液体中液体的液面显示流量。堰口和捡拾开口的尺寸和形状是可调节的，以使得流过装置的流量达到用于显示器的适当范围。

摘要： A Fourdrinier-type paper machine having a wet end with a headbox for storing a mixture of pulp and water, this pulp mixture being jetted onto a fabric having two side edges, this fabric forming an endless belt the upper surface of which is caused to continuously move away from the headbox, including an apparatus for continually supporting and curling the edge of the fabric so as to prevent loss of pulp mixture off the sides of the fabric and so as to prevent edge wave formation which would require substantial trimmage and waste. The apparatus includes a pair of bars having a wedge-shaped cross-section, one edge of each inserted under one side of the fabric, to cause the edge of the fabric to curl upward. Apparatus is provided to adjust the amount of curl. Several of these curl adjusting apparatuses are placed along the length of the bars so that the amount of curl can be different at different points along the bars. For instance, the curl might be greatest at the point where the pulp hits the fabric, and it may be slowly tapered to zero over the length of the bars. The upper surface of the fabric is also caused to continuously move from side to side, and an end block is provided at the leading edge of each bar to prevent the fabric from running off the edge of the bar during the course of any lateral movement of the fabric.
摘要翻译：一种具有湿端的长网造纸机，其具有用于储存纸浆和水的混合物的流浆箱，该纸浆混合物被喷射到具有两个侧边缘的织物上，该织物形成环状带，其上表面连续地连续远离流浆箱，包括用于连续支撑和卷曲织物边缘的装置，以防止纸浆混合物离开织物侧面的损失，从而防止需要大量修剪和浪费的边缘波形成。该装置包括具有楔形横截面的一对杆，每个条插入织物一侧的一个边缘，以使织物的边缘向上卷曲。提供设备以调节卷曲量。这些卷曲调节装置中的几个沿着条的长度放置，使得沿着条的不同点的卷曲量可以不同。例如，在纸浆撞击织物的地方，卷曲可能是最大的，并且其可以在条的长度上缓慢地变成零。织物的上表面也从一侧到另一侧连续移动，并且端块设置在每个杆的前缘处，以防止织物在任何横向运动过程中从杆的边缘流出面料。

摘要： A composite is provided for forming a sealing strip for use in a suction roll of a papermaking machine that has extended usability and wear. The composite is a blend of a nitrile rubber, graphite, carbon black, and polytetrafluoroethylene, optionally with a phenolic resin. The sealing strip has polytetrafluoroethylene evenly distributed over the contact surface and when installed into a suction roll provides a reduced frictional surface.
