ABSTRACT:
A metering unit (12) is attached to the robot (10) for providing two polymeric materials to a dispenser/mixer module (14) attached to the end of the robot arm (16). The metering unit includes piston (44) located concentrically about the shaft (42) of a dual actuating piston assembly (36) for providing the two polymeric materials in a fixed ratio. A variable rate dispenser (62) is provided for compensating for changes in robot velocity and/or viscosity changes.
