Abstract
An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.
