摘要： A hot melt adhesive dispensing system that includes a hand held gun and a molten adhesive source, the gun and the source being selectively connectable one with the other in a novel manner to permit charging and recharging of the gun with molten adhesive from the molten adhesive source. The hand gun includes novel charge valve structure adapted to interconnect with novel feed valve structure mounted on the hot melt adhesive source so as to accomplish transfer of a hot melt adhesive charge in molten form, from the source to the gun storage chamber. The adhesive is pressurized within the gun's storage chamber by a novel pressure device at least partially incorporated within the storage chamber, thereby providing the motive force to cause discharge of molten adhesive from the gun's nozzle in response to manual activation of the gun's trigger.

摘要： The invention concerns apparatus, preferably a trigger-actuated portable gun, for dispensing adhesive comprising a housing containing a feed passage for receiving normally solid but heat-liquefiable adhesive block(s) having a flange for forming a fluid-tight yet yieldable seal with the feed passage, an outlet for liquefied adhesive, a coupling for connection to a source of pressurized fluid whereby in use fluid pressure is applied directly to the block(s) in the feed passage without the intermediation of a mechanical piston to advance the block(s) towards the outlet, and a heater for progressively liquefying the leading and of the block the remainder which serves as a piston for the liquefied portion thereof.

摘要： A hot melt gun for use with a cartridge of thermoplastic adhesive and in which a bead of melted adhesive is forced out of a gun nozzle by pneumatic action for efficient high volume bonding. The gun includes apparatus preventing blockage of the air supply line which can be caused by the backup of molten adhesive within the gun, while not detracting from overall gun performance.
