<p>A glue melting gun construction which permits coordination with automated machine and/or is capable of performing long distance or continuous coating of glue avoiding manual feed control of existing guns, the gun comprising a glue melting tube (24) surrounded by a heater (25) for melting glue into liquid form, and a bolt (23) disposed in the glue melting tube and driven by a motor on actuation of a switch (221) whereby the bolt urges liquid glue from an outlet (243). The gun has a head (26) fitted to the end which provides a one way valve (261,262) acting on the outlet to stop flow of liquid glue when the motor stops driving the bolt</p> |
