Abstract: An adhesive dispensing gun for translating solid slugs of thermoplastic feedstock from the solid state to a molten state. The gun is pneumatically cooled to control solid/melt feedstock interface within the gun's barrel and is pneumatically powered to discharge the molten feedstock in response to operation of a trigger. The gun barrel includes a forming die adapter or sleeve located partially upstream of the solid/melt feedstock interface. The upstream end of the adapter or sleeve is flared inwardly so as to form a section internally of the barrel for reforming or reshaping varying sized slugs as they enter the forming die adapter and while the entering section of the slug is still in a solid state. The forming die adapter thus enables the adhesive gun to accept varying sizes of slugs while preventing meltback along the exterior of slugs which are nominally substantially smaller in diameter than the inside diameter of the barrel.
