Abstract
In a device for melting a body of solid thermoplastic adhesive material, a melting chamber is located within the housing and the adhesive material is fed into the melting chamber by a feed apparatus. A rubber-like elastic gasket is located at the inlet end of the chamber providing a seal around the adhesive material entering the chamber for preventing leakage of molten material back into the housing. An insulator ring formed of a thermostable, poor heat conducting material is located between the melting chamber inlet and the gasket to limit the passage of heat to the gasket. Preferably, the insulator ring is formed of TEFLON.
