The Servo-Ribbon Applicator (SRA) is a new concept in dispense-valve applicator tools. It combines an AC Servo-Motor and fluid-dispense valve to robotically position the valve's tip at the correct angle to deliver a precise ribbon-shaped material pattern. While following the bead path, the SRA valve turns the dispense tip without turning the fluid-dispense valve. This unique dispensing action significantly improves the valve's reach, material-flow rate, tip-speed, and cycle time while increasing the service life of moving parts such as robot wrists, hoses, and cables. The SRA valve is ideal for fixed, automated or robotic fluid-dispensing applications with shaped-orifice fluid nozzles such as a slotted ribbon tip, fan-spray tip or a side-outlet extruded-bead tip.
