<p>A hot melt adhesive material flow control system comprises an input manifold for receiving a supply of adhesive material, a plurality of flow control valves from which the adhesive material is discharged, an output manifold for heating the adhesive material and conducting the hot melt adhesive material to the flow control valves, a pair of multiple outlet pumps for supplying the adhesive material to the flow control valves, and a recirculation pump for recirculating adhesive material back from the flow control valves to the pair of multiple outlet pumps. A distribution plate and a recirculation plate are interposed between the input and output manifolds and have separate and independent fluid circuits or flow paths defined upon opposite surfaces thereof. In this manner, the number of plates required to define the flow paths is significantly reduced. In addition, the output manifold, the flow control valves, the recirculation pump, and the multiple outlet pumps are independently mounted upon the input manifold so as to simply disassembly and reassembly of the components in connection with maintenance, cleaning, replacement, or repair operations. <IMAGE></p> |
