ABSTRACT:
Method and apparatus are disclosed for cyclically metering charges of a granulated wax-like or resinous material from a bulk supply and feeding such metered charges into a heated, pressurized reservoir. Each charge of the granulated material is fluidized with a stream of air under pressure to insure flow of the granules. The stream of air also serves to pressurize the reservoir and prevent the escape of hot air therefrom. Cooling of the reservoir inlet to prevent agglutination of the granules also is contemplated.
