Disclosed is an apparatus for applying a viscous liquid material and a method of controlling the discharge of the viscous liquid material. The apparatus has a movable nozzle having a port for discharging the viscous liquid material in a predetermined discharging direction. The nozzle is movably arranged to controllably trace a predetermined track. A shutter for controllably closing the port of the nozzle includes a shiftable member arranged on the port to move relative to the port between a first position and a second position along a plane which crosses the discharging direction of the nozzle so that the shiftable member release and covers the port of the nozzle. The present invention is suitable for application on a loop track or a closed path. In the method, it is preferred that the first position is located on the front side of the second position facing toward a direction in which the nozzle advances at termination of tracing with the viscous liquid material.
