Abstract
A method and apparatus for applying fibers to a foraminous mold or surface using strands of binder and glass fibers is disclosed. A strand of binder fiber is chopped and entrained into a chute. The chute has a longitudinal airstream directed therethrough toward the foraminous surface. The binder fiber is separated into filaments by the airstream. The glass fiber strand is chopped and entrained into the chute downstream of the filaments. The chopped glass and the binder filaments mix within the chute and are then directed by the airstream onto the foraminous mold or surface. The mixture may be fanned out from the chute to provide more even coverage of large sized molds or surfaces.
