The present invention is directed to an apparatus and method for dispensing hot melt adhesives in controlled precise amounts. The quantitative displacement dispenser mounted to the programmable moving system is connected to the hot melt cartridge feed assembly by an inlet block. The distributor, feed assembly, and inlet block include an electric heater and thermocouple to maintain the adhesive at the desired temperature. The computer control system regulates the temperature in the dispenser, the feed assembly, and the inlet block, and controls the dispense motor in the dispenser. The preheat heater heats the adhesive cartridge before it is placed in the feed assembly. |
