Abstract: A material pressure feeding apparatus 10 includes a sack 11 containing material M having predetermined viscosity, a container 12 for holding the sack 11, a press member 13 disposed within the container 12 and positioned on the sack 11, a pressure feeder 15 having a suction port 37A for sucking the material M for lowering the press member 13 to pressurize the sack 11 containing the material M. The press member 13 includes a plate 21 having a plane-shape substantially identical to the opening 19 of the container 12, and a tubular member 22 along the inner peripheral side surface of the container 12, hanging vertically from the outer periphery of the plate 21 and forms a reception space 23. The press member 13 descends to reduce the volume of sack 11 forming wrinkled portion S and the wrinkled portion S is settled in the reception space 23.

Abstract: 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.
