DEVICE AND METHOD FOR APPLYING APPLICATION LIQUID

摘要

A device for applying an application liquid to the upper surface of a glass plate having an irregular shape provided with a concave center portion. The device has a nozzle height adjusting means (30) for adjusting the heights of application nozzles (2), a nozzle position adjusting means (10) for adjusting the horizontal positions of the application nozzles (2), and a controller for supplying the application liquid by opening the application nozzles (2). The constitution enables even and uniform application of the liquid. In a device for applying an application liquid to the upper surface of a rectangular glass plate, the distance between band-shaped application surfaces to which the application liquid is ejected from application nozzles (11) is set in the range from a/4 to a/30 (where a is the width of a band-shaped application surface). The construction can make the film thickness uniform by leveling performed after a predetermined time is elapsed.
