ABSTRACT:
A method for depositing flock wherein flock fibers are fed at a controlled rate from a storage hopper through a screen into a propelling air stream. The air stream carries the fibers in a rotationally stabilized flow whereby turbulence is prevented, to an applicator gun where they may be electrostatically charged, and they are propelled by the air stream and deposited on the adhesively coated surface to be coated.
