ABSTRACT:
A hot melt adhesive dispensing system including a hot melt adhesive dispenser, a hot melt adhesive tank, and a hose for coupling hot melt adhesive from the tank to the dispenser. The dispenser, the tank and the hose are heated by electrical heaters to maintain the adhesive in a suitable molten condition for dispensing and for flowing from the tank to the dispenser. When the hot melt adhesive system is first energized, the hose and tank heaters are coupled to a source of electrical power and the temperature at either the tank or the hose is sensed. When the sensed temperature reaches a suitable preselected level, the dispenser heater is then energized by coupling the heater to a source of electrical power. In this way, as the adhesive in the dispenser is heated from a solid to a molten form, it is free to expand into the hose, with the adhesive in the hose adjacent the dispenser having already been heated to a molten state.
