ABSTRACT:
An apparatus for melting and dispensing thermoplastic material comprising a hopper, a grid melter, a reservoir and a pump. The novel grid melter comprises a plurality of upwardly extending frustoconical melting elements formed on the bottom wall of the melter. The pump is also novel and comprises a unique infeed system for forcibly moving molten material into the pump inlet. The apparatus lends itself to a modular building block concept in which differing manifold blocks, pumps and drive motors, as well as applicators may be utilized in combination with the grid melter and/or reservoir to create differing operating characteristic dispensing systems.
