SLIDING AIR NOZZLE APPARATUS

摘要

Disclosed is a sliding nozzle apparatus capable of uniformly drying and curing an object like a volatile coating agent which is thinly coated without the failure of a quality. The disclosed sliding nozzle apparatus includes: a lower air pocket which is arranged under the object to be cured, and is filled with air of a higher temperature than room temperature which is introduced from the outside; and a parallel discharge chamber which is fixed to the upper side of the lower air pocket, receives the high-temperature air from the lower air pocket, and discharges the air toward the object to be cured. The parallel discharge chamber includes a curved guide to guide the high-temperature air to be discharged through a discharge hole as the air moves along a curved path therein. An angle between an extension line in the direction where the high-temperature air is discharged, and an extension line in the direction where the object to be cured travels is 0 to 30 degrees in the discharge hole.
