摘要： An improved nozzle of the type which directs a flow of fluid against a moving substrate to obtain a uniform surface coating on the substrate. The nozzle consists of two rigid body halves mounted on a fluid feed pipe. One body half is fixed, and the other body half is rotatably mounted on the feed pipe for adjusting the size of the nozzle discharge opening. One or more closure loading assemblies are mounted on the nozzle for adjusting the size of the discharge opening and for maintaining the nozzle opening in an adjusted position. Each closure loading assembly has a fluid-actuated cylinder which forces the body halves toward a closed position opposing the internal fluid pressure in the nozzle body in combination with an adjustable differential screw. The adjustable screw is mounted on one of the body halves and engages a stop on the other body half to set the size of the nozzle discharge opening. The closure-loading assemblies will maintain the adjusted nozzle opening even after opening and closing of the nozzle for cleaning and will permit adjustment of the discharge opening during operation of the nozzle. The feed pipe is connected to a source of fluid and distributes the coating control fluid throughout the length of the nozzle through a plurality of spaced holes formed in the feed pipe and nozzle body halves. Each closure loading assembly and stop screw effectively acts in a common plane perpendicular to the transversely extending fluid feed pipe.

摘要： A mechanism for cleaning the discharge opening lips of a coating control nozzle by controlled movement of a plurality of brushes transversely along the nozzle lips. A carriage is mounted on a support frame and is moved along the frame by a rodless cylinder. A plurality of brushes rotated by air motors are mounted on the carriage and are moved along the nozzle lips for cleaning by the carriage. The brushes are mounted on one end of a bellcrank which is attached to the carriage and are pivotally moved into and out of engagement with the nozzle lips by a fluid actuated cylinder mounted on the carriage. One of the brushes engages and cleans the inside surfaces of both nozzle lips simultaneously with two pairs of brushes which clean the outside surfaces of both lips as the carriage moves the brushes transversely along the nozzle opening. A stop is engaged by the bellcrank to limit the pivotal movement of the bellcrank to position the brushes with respect to the nozzle lips. The brushes may be replaced with scraper blades mounted on the end of the bellcrank.
摘要翻译： 一种用于通过沿喷嘴嘴横向地多个电刷的受控运动来清洁涂布控制喷嘴的排出口的机构。 滑架安装在支撑框架上，并通过无杆气缸沿框架移动。 通过气动马达旋转的多个电刷被安装在滑架上并且沿着喷嘴嘴移动以便通过托架清洁。 电刷安装在一个曲拐的一端，该曲拐通过安装在滑架上的流体驱动的圆柱体安装在滑架上并与枢轴运动进入和离开与喷嘴嘴接合。 其中一个刷子与两对刷子同时清洁两个喷嘴嘴唇的内表面，两对刷子随着滑架沿着喷嘴开口横向移动刷子，从而清洁两个嘴唇的外表面。 由曲拐接合止挡件以限制曲拐的枢转运动，以使刷子相对于喷嘴嘴定位。 刷子可以用安装在曲拐末端的刮刀代替。

摘要： A fluid nozzle for use in coating a traveling web has an elongated nozzle body formed by a first rigid boxlike section having a pair of converging walls and a second less rigid section pivotally mounted on the first section. A pair of lips are mounted on the nozzle body sections and define a nozzle opening through which fluid is discharged from a fluid chamber formed within the first body section and directed against the web. One of the lips is mounted on one of the converging body walls and the other lip is mounted on a support plate forming part of the second body section for adjusting the size of the fluid discharge opening. The support plate and attached nozzle lip of the second section are pivotally moved with respect to the first section by a plurality of levers which are moved in unison by pressure actuated cylinders or by two continuous pressure actuated tubes mounted between the support plate and nozzle body. The cylinders or tubes move the pivotally mounted lip away from the other lip to increase the size of the discharge opening for cleaning the nozzle lips and return the lips to the coating position without requiring any change to the lip settings. One or more spaced adjustment wedges also may be slidably mounted between the nozzle body wall and slide plate for adjusting the size of the discharge opening while the nozzle is "on line". The pair of nozzle body sections are provided with mating surfaces which are clampingly engaged when in the coating position.
摘要翻译： 用于涂布行进幅材的流体喷嘴具有细长的喷嘴体，其由具有一对会聚壁的第一刚性盒状部分和可枢转地安装在第一部分上的第二较小刚性部分形成。 一对嘴唇安装在喷嘴主体部分上并且限定一个喷嘴开口，流体从形成在第一主体部分内的流体室排出并且被引导到纸幅。 其中一个唇缘安装在一个会聚体壁上，另一个唇缘安装在形成第二体部分的支撑板上，用于调节流体排出口的尺寸。 第二部分的支撑板和附接的喷嘴唇缘通过多个杠杆枢转地相对于第一部分移动，多个杠杆通过压力驱动的缸体或由安装在支撑板和喷嘴体之间的两个连续的压力致动的管道一起移动。 气缸或管将可枢转地安装的唇缘从另一个唇缘移开，以增加排出口的尺寸，以清洁喷嘴嘴唇，并使嘴唇返回到涂覆位置，而不需要改变唇部设置。 一个或多个间隔开的调节楔也可以可滑动地安装在喷嘴主体壁和滑板之间，用于在喷嘴“在线”时调节排出口的尺寸。 一对喷嘴主体部分设置有当处于涂覆位置时夹紧接合的配合表面。

摘要： Coating apparatus for applying a coating liquid to a moving roll. The apparatus has a trough-like pan, longer than the width of the roll surface to be coated, for holding a supply of the coating liquid. A pair of weirs is mounted on the pan which holds the coating liquid partially impounded therebetween. The weirs are spaced closer than the ends of the roll and the width of the roll surface to be coated. The weirs each are formed with a curved concave central portion having a radius the same or slightly larger than the radius of the roll, and with at least one overflow end portion to serve as a spillway. Coating liquid is supplied continuously to the central portion of the pan between the weirs and is drained continuously from the weir overflow end portions. The level of the coating liquid between the weirs is maintained at a higher level than coating liquid outside the weirs. The roll may serve as a backup roll for a strip passing around it or as a transfer roll to transfer the coating liquid from the pan to a strip in contact with the upper portion of the roll.A method of applying a coating liquid to one side of a strip of material by providing a body of coating liquid between a pair of spaced weirs which are mounted on a trough-like container. The material to be coated extends laterally beyond the weirs and is passed through the body of coating liquid in a curved path beneath a backup roll which is partially submerged in the coating liquid. The weirs each have a curved portion and at least one end overflow portion communciating with collecting compartments beyond the weirs. The coating liquid level in the collecting compartments is maintained below the lowest level of the curved weir portions whereby the excess coating liquid from the liquid body flows over the weir overflow portions, into the collecting compartments.
