Abstract: A hot melt system is configured to generate liquid adhesive from solid adhesive pellets. The liquid adhesive is applied to components, such as box tops, to fix components together. A melter is configured to melt the adhesive pellets into the liquid adhesive. Adhesive pellets are periodically fed from a hopper to the melter to maintain a constant supply of liquid adhesive. An adjustable flow restrictor is disposed upstream of a feeder that displaces the adhesive pellets from the hopper to the melter. The adjustable flow restrictor is adjustable to change a flow of the compressed gas flow to the feeder. Adjusting the flow of the compressed gas flow adjusts the feed rate of the adhesive pellets from the hopper to the melter.
