Abstract
Apparatus for melting and applying meltable adhesive in which a separate melting insert including a melting wall is interposed between the melting chamber and the application device. The melting wall is formed with projections or cones, and channels for passing molten adhesive to the nozzle body of the application device. A piston in the melting chamber presses a unit of adhesive against the melting wall. The melting wall is independently heated by a heater and controlling temperature sensor. The nozzle body and melting insert/melting wall are formed of different metallic materials, the latter being made of light metal alloy for better thermal conducting response. The melting insert forming the melting wall is removable to facilitate the cleaning and maintenance.
