ABSTRACT:
This invention relates to a feeder 10 for glass fibers useful in feeding glass fibers to a wet-mat process. Previous fiber feeders were unreliable and caused process disruptions primarily due to fiber conveying belt breakage. Belt breakage in the present fiber feeder is substantially eliminated by providing a belt pulley comprising an open-ended cylindrical drum 52 having a plurality of staggered waste fiber intake openings 54 longitudinally and circumferentially distributed over the drum. The intake openings 54 are staggered and sized to eliminate interference with the motion of slats 60 which comprise the fiber conveying belt 50, to ensure sufficient flow of waste fiber 36' out of the drum 52 and to eliminate any potential accumulation of waste fiber 36' between the belt 50 and the belt pulley 48.
