ABSTRACT:
An apparatus and method for dispensing controlled precise amounts of a hot-melt adhesive. A positive displacement dispenser which is mounted on a programmable motion system is connected to a hot-melt cartridge feed assembly by an inlet block. The dispenser, feed assembly, and inlet block contain electric heaters and thermocouples for maintaining the adhesive at a desired elevated temperature. A computer control system regulates the temperature in the dispenser, feed assembly, and inlet block and controls a dispensing motor in the dispenser. A preheater heats an adhesive cartridge prior to placement in the feed assembly.
