摘要： A technique for forming single or multi-layer sheets of fibrous material having a controllable fiber distribution is described. A pair of spraying rollers each having a system of circumferentially spaced radial vanes on its surface are supported within the upper portion of a working zone defined between a pair of continually advancing, downwardly converging sieves that are disposed symmetrical to a longitudinal axis. The rollers are rotated in respectively opposite directions to intercept at least one fibrous suspension downwardly directed into the working zone, and to thereafter propel the intercepted liquid outwardly and downwardly toward the sides of the working zone in symmetrical fashion. The fibrous layers thus built up on the advancing sieves converge into the final sheet in the lower portion of the working zone. Separate facilities are associated with the upper and lower portions of the working zone for drawing liquid from the formed layers outwardly through the sieves.
