Abstract
Systems, feeder devices and methods for moving particulate hot melt adhesive from an adhesive supply to an adhesive melter. A feeder device includes a body having an inlet and an outlet, and an interior communicating with the inlet and the outlet. The inlet is configured to receive particulate hot melt adhesive from an outlet of the adhesive supply, and the outlet is configured to provide particulate hot melt adhesive to an inlet of the adhesive melter. The feeder device further includes a mechanical agitator positioned in the interior for urging the particulate hot melt adhesive in a flow direction toward the outlet.
