Abstract
A hot melt body for an applicator or dispenser of thermoplastic adhesive first received in solid form, either as a progressively fed rod or in another mode, is provided having especial advantage in a light-weight hand-type device. The main melt chamber and its auxiliary channels as well as their interconnecting passageways are of configuration and spacing to effect maximum efficiency in transfering melting heat from a heating means to the adhesive being liquefied. To this end, also, complemental portions of the body include passageways designed to provide minimum, substantially uniform resistance to advance of the solid adhesive along the length of the melt body.
