COATING NOZZLE FOR HIGH-VISCOSITY PAINT

摘要

A coating nozzle (10) for a high-viscosity paint is equipped with an introduction passage (17), an inner space (16), and a nozzle slit (15), which communicate with one another, and sprays a coating body with the high- viscosity paint from the nozzle slit (15) in a radial direction. The nozzle slit (15) is constructed in a sectional shape having predetermined angle in a plan view. When the nozzle slit (15) is regarded as having the sectional shape, an arc of the sectional shaped nozzle slit (15) serves as a nozzle slit outlet (15E). The nozzle slit outlet (15E) has a nozzle slit outlet width (W) equal to or large than 35 mm and a flattening (F) equal to or smaller than 0.01 where a slit height (D) represents a clearance of the nozzle slit outlet (15E), the nozzle slit outlet width (W) represents a chord of the arc, and the flattening (F) represents a ratio of the slit height (D) to the nozzle slit outlet width (W).
