摘要： A method and apparatus for treating a layer of fibrous material with a liquid in operations such as the scouring of wool fibers, the fibers being arranged into a thin layer between porous conveyors and conveyed by them through a body of treating liquid, the layer being subjected to a series of nipping actions which cause liquid to flow along the layer of fibers, the flow of liquid through the layer in a direction normal to the plane of the layer being maintained. It is preferred that the nipping devices should be in the form of nipping members which have a surface arranged at an acute angle to the surface of one of the conveying members so as to define a wedge-shaped space, the arrangements of these members being such as to maintain a hydrodynamic pressure gradient across the layer of fibers thus promoting a uniform unidirectional flow of liquid through the fibers.
