Abstract
A system and associated method for preparing a composite sheet material is provided. The system includes a nonwoven fabric source; a collection surface onto which a nonwoven fabric is deposited; a carding device disposed downstream of the nonwoven fabric source overlying the collection surface, the carding device including a main cylinder, an air source configured to provide a stream of air; an air manifold having an air inlet in communication with the air source, an air outlet, a fiber inlet, an interior channel, and a fiber outlet. The air outlet is positioned to direct an air stream against a surface the cylinder to dislodge fibers from the surface of the cylinder. The dislodged fibers enter the fiber inlet and flow to the fiber outlet at which point the fibers are deposited onto a surface of the nonwoven fabric. The fabrics are then bonded to form a coherent sheet material.
