ABSTRACT:
A system for supplying melted thermoplastic material to a dispenser comprises a hopper for storing solid thermoplastic material. The hopper has interior side walls and an outlet. A reservoir block is located below the hopper. The reservoir block includes a reservoir into which melted material may flow from the hopper. A manifold and pump assembly is connected to the reservoir block for receiving material from the reservoir and pumping the material to a dispenser. A heating grid at the outlet of the hopper heats and melts the solid thermoplastic material in the hopper. The grid comprises a block which is spaced from the interior sidewalls of the hopper. The grid is thus thermally isolated from the exterior of the system resulting in more efficient heating of the material.
