A liquid coating nozzle is provided with a first block which has an inner liquid reserving section that extends in the longitudinal direction and an inner discharge section which includes a plurality of small holes formed in the longitudinal direction at a bottom portion of the liquid reserving section. The nozzle is also provided with a second block which has an inner space defining a gas reserving section that extends in the longitudinal direction outside the first block and an outer discharge section formed in the longitudinal direction at a bottom portion of the inner space. The outer discharge section includes a plurality of small holes and produces a gas flow that externally surrounds a linear or curtain-shaped liquid flow that flows downward from the small holes. This results in the formation of a thin coating film in a short time and reduces the consumption of liquid and coating nonuniformities.

The present invention aims to form a thin coating film of even thickness within a short processing time under a curtailed consumption of coating liquid; where, a gas is spouted from nozzle 4 disposed facing to protection glass 2 of cathode ray tube, and a liquid containing fluorescent material is made to spout accompanied by the spouting gas, to be applied on protection glass 2 by shifting the positioning of protection glass 2 relative to nozzle 4 while spouting the liquid containing fluorescent material.

A coating apparatus includes: a block-shaped die main body; upper and lower nozzle parts projecting from the die main body to form a nozzle, forward end portions of the upper and lower nozzle parts being substantially cylindrical and each of the portions having a constant curvature, the forward end portion of the upper nozzle part serving as a guide, a discharge opening having a slit-shaped sectional configuration being provided in the guide, a bottom surface of which is lower than a surface of the guide; a coating material reservoir, provided in the die main body, communicating with the discharge opening; a groove formed between the upper and lower nozzle parts, through which the discharge opening communicates with the reservoir; a partitioning plate mounted widthwise substantially entirely on one of the forward end portions of the upper and lower nozzle parts so that the partitioning plate is movable through the nozzle to open the groove; a rotary block pivotably supporting the die main body for rotation through a specified angle; and a solvent reservoir, provided below the lower nozzle, for receiving the forward end portions of the nozzle which has moved downward by pivotal motion of the die main body with the rotary block.

Coating apparatus

A coater has a die member for discharging a coating material, and a pad member for supporting a web to be fed at a predetermined position and for controlling the gap sensitively to manufacture a coating film. The coater can flow a debris to downstream by moving the pad member away from the web.
