    • A coating apparatus wherein the coating is made by a coater while a support is carried in a non-contacting manner by a gas jetted from a gas jetting device towards the support. The gas jetting device has a hollow housing into which the gas is introduced from a gas source, the wall of the housing adjacent to the support being provided with a plurality of gas jetting nozzle ports through which the gas is jetted towards the support, each gas jetting nozzle port having a throat portion presenting a minimum cross-sectional area inwardly spaced from the outer surface of the wall of the housing and an enlarged outlet portion presenting a comparatively large diameter and opening in surface of the wall. The ratio of port area is adjusted in such a manner that the rate of jetting of the gas from unit area of the outer surface of the gas jetting device becomes smaller as the width of the support is increased.
    • 一种涂覆装置,其中涂层由涂覆机制成,而支撑体以非接触方式通过从气体喷射装置向支撑件喷射的气体运送。 气体喷射装置具有中空壳体,气体从气体源引入到其中,与支撑件相邻的壳体的壁设置有多个气体喷射喷嘴端口,气体朝向支撑件喷射,每个气体 具有喉部的喷射喷嘴端口具有与壳体的壁的外表面向内间隔开的最小横截面面积,以及具有相对较大的直径并且在壁的开口表面的扩大的出口部分。 端口面积的比率被调节为使得气体从气体喷射装置的外表面的单位面积喷射的速率随着支撑件的宽度增加而变小。
