ABSTRACT:
An apparatus for melting and dispensing thermoplastic material comprising a hopper, a grid melter, a reservoir and a pump. The novelty of this application resides in a novel method and apparatus for forcing molten material into the pump inlet. The infeed is accomplished by a pair of counter-rotating shafts to which the molten material is supplied and from which it is sheared by a pair of inclined surfaces. In the process of being sheared from the counter-rotating shafts the molten material is forced into the pump inlet.
