Abstract
A system for forming an air laid web of fibers and/or particles on a moving foraminous carrier. Fibers and/or particles are blended, and while supported in an air stream, introduced into a distributor unit. The distributor unit includes a rotatable cylinder formed with classification apertures of a predetermined shape, number, and size as specifically related to the types of fibers and/or particles utilized. A rotatable shaft with radially extending wire-like members agitates the fibers and/or particles and throws them outwardly through the apertures. Downwardly directed air flow transports the refined fibers and/or particles so as to form a homogeneous, still further refined, web on the surface of the carier. A variety of adjustments and alternations can be made to the system and its components to control the composition and thickness of the end product, and to attain maximum capacity for any combination of fibers and/or particles.
