(54) Hot-melt guns


(57) Hot-melt gun especially for adhesives with trigger-operated feeding means using at least one contin­uous feed-belt or-chain to engage a glue-stick so as to feed it to the melt-chamber of the hot-melt gun. Pre­ferably the feed-belt is driven by an electric motor and may be provided with outward-facing hooks adapted to engage a glue-stick. A twin-belt arrangement feeding the glue-stick between the belts is described. The second belt may be positively driven or may function as an idler. A computer logic device may be incorporated.
