ABSTRACT:
Apparatus for dispensing a hot melt thermoplastic consists of a hopper containing granular thermoplastic, an extruder for melting the molten thermoplastic and delivering it to a manifold and then to an applicator for dispensing the molten thermoplastic. Optionally an accumulator can be attached to allow the molten thermoplastic to accumulate during off-periods of the applicator. Operation of the applicator controls operation of the extruder and the accumulator.
