Abstract
In a hot melt glue dispensing gun, apparatus is constructed to feed a flexible rod of glue to a heated melt chamber. This apparatus includes two motor driven gears which engage the glue rod and feed the glue to the melt chamber. This feed mechanism is mounted on a sliding frame which is spring biased to retract when the appliance is idling, thereby partially withdrawing the glue rod from the melt chamber.
