摘要: A uniform film of coating is delivered onto a substrate at high speed by a film applicator, such as a coater apparatus for a papermaking machine, which has a static converging wedge, an adjustable converging wedge, and an extraction channel located between the two wedges. As a unit, the film applicator minimizes the hydrodynamic flow instabilities, as well as reduces flow variations associated with a nonuniform feed and a dynamic contact line. The film applicator also removes entrained air and excess coating from the application zone in order to improve the flow stability and machine runnability.

摘要: A doctor blade structural support has the form of a hollow structural member of roughly triangular cross-section, one side of the triangular cross-section being substantially tangent to the surface of the dryer roll. A quantity of water is disposed within the hollow structural member and resides on the inside surface of the structural member adjacent to the heated dryer roll surface. The interior of the doctor support structure is sealed from the atmosphere and is evacuated so that the interior of the structure contains only water and water vapor. Heat radiating from the dryer roll surface to the doctor support structure causes water disposed on the inside surface adjacent to the dryer roll to evaporate, thus raising the internal vapor pressure in the sealed interior of the doctor support structure. The water vapor continuously condenses on the inside surfaces of the support structure which are not exposed to radiant heating from the dryer roll. This evaporation and condensation of water within the interior hollow support structure maintains relative temperature uniformity from top to bottom of the support structure. The temperature uniformity in turn leads to a minimizing of thermal distortion caused by the heat transfer between the doctor support structure and the dryer roll.
摘要翻译: 刮刀结构支撑件具有大致三角形横截面的中空结构构件的形式,三角形横截面的一侧基本上与干燥器辊的表面相切。 一定量的水被设置在中空结构件内并且位于与加热的干燥辊表面相邻的结构件的内表面上。 医生支撑结构的内部与大气密封并被排空,使得结构的内部仅包含水和水蒸气。 从干燥辊表面散发到刮刀支撑结构的热量使得设置在与干燥器辊相邻的内表面上的水蒸发,从而提高了医生支撑结构的密封内部的内部蒸气压。 水蒸气在支撑结构的内表面上连续地冷凝,该表面不受干燥辊的辐射加热。 内部空心支撑结构内的水的蒸发和冷凝保持了从支撑结构的顶部到底部的相对温度均匀性。 温度均匀性又导致由刮刀支撑结构和干燥器辊之间的热传递引起的热变形的最小化。

摘要: A press mechanism and method for removing liquid from a traveling fibrous web such as in a paper making machine including first and second elongate extended press nips including an endless looped traveling belt passing over spaced guide rolls with first and second opposed press rolls pressed into the belt to form the extended nips between the press rolls and belt and opposed shoes within the belt pressing outwardly against the press rolls to form the extended nips with the shoes urged against the belt by opposed pistons having a liquid pressure chamber therebetween so that the reaction forces of the fluid on the pistons are cancelled with the web being carried through the nips on felts and following the belt between the nips.

摘要: A press structure for performing a dewatering operation in the steps of formation of a traveling fibrous web such as in a paper making machine wherein the wet web is carried on one or more water absorbing felts through a press formed of a pair of extremely tough liquid impervious belts with the belts backed throughout a pressing zone by a series of fluid pressure chambers applying hydraulic pressures to the back of the belt. The chambers are arranged so that a first fluid pressure is applied at a first portion of the pressing zone, and subsequently a second higher pressure is applied to the belts at a second portion of the pressing zone and thereafter a third pressure is applied at a third portion. Each successive pressure is higher than the previous one so that the hydraulic resistance pressure of the moisture leaving the web does not build up at such a rate so as to disrupt the web fibers.

摘要: A short dwell coater apparatus is disclosed for applying coating material to a web supported by a backing member. The apparatus includes a housing which defines an application zone having an upstream and a downstream end. The application zone extends in a cross-machine direction across the web and is connected to a source of the coating material such that the coating material is applied to the web during movement of the web past the application zone. An elongate pipe is disposed within the application zone and extends in a cross-machine direction across the application zone. The pipe defines at least one orifice for the passage therethrough of the coating material. The pipe is connected to the source of coating material such that the coating material flows through the pipe and through the orifice for supplying coating material to the application zone. A vane is rigidly secured to the pipe and extends in a machine direction away from the pipe towards the web such that coating material supplied through the orifice generates a hydrodynamic wedge between the vane and the web for reducing entrained air vortices within the application zone. A metering blade is disposed adjacent to the downstream end of the application zone for metering excess coating from the web.

摘要: A method and apparatus for dry forming a paper, or other nonwoven web, from fibers or fiber flocs. The flocs or bundles are exposed to an oscillating electrostatic field, the resultant mechanical agitation shakes individual fibers loose, which then fall through a screening wire onto a moving forming wire. At a station downstream from the forming section a binder is applied. After appropriate conditioning, the newly formed web is picked off for further processing.
