Abstract

Apparatus for and methods of forming, from a single column of fibers, an airlaid fibrous web having a multiplicity of components. The apparatus is of the type which includes a first laydown drum having a first foraminous forming element; a second laydown drum having a second foraminous forming element; a splitter chute apparatus for splitting a column of fibers into a multiplicity of fiber streams and for entraining each of the fiber streams in air so as to provide a multiplicity of streams of air-entrained fibers; a first deposition chute for directing a first stream of air-entrained fibers from the splitter chute to the first laydown drum; a second deposition chute for directing a second stream of air-entrained fibers from the splitter chute to the second laydown drum; a dusting layer deposition chute for directing a dusting layer stream of air-entrained fibers from the splitter chute to the first laydown drum; and a uniting apparatus for uniting a first web component that is formed on the first laydown drum with a second web component that is formed on the second laydown drum to form an airlaid fibrous web having a multiplicity of components.
