Abstract
A dispenser of viscous fluid, in at least one embodiment a hot melt glue adhesive, has a heater element, an adhesive source, a main common passage, and a series of valves that all fluidly connect to the main passage. A sheet of receiving material, such as an envelope, has hot melt glue applied to its surface as it passes under the series of valves. A variable amount of valves can be activated by moving control rods inwardly or outwardly of the main common passage. The moving control rods have indicator markers, a securing screw and are housed in U-shaped beds which collectively make adjusting the dispensing pattern very easy.
