Abstract
A paint curtain machine for coating a substrate with paint has a fix mounted guide plate at either edge of the curtain for guiding and determining the edges of the falling paint curtain that otherwise tends to draw together and pour or at least to wrinkle and produce uneven paint coatings. The inner edges of the guide plates to which the paint curtain edges cling by capillarity are sloped inwardly toward the bottom of the curtain. Excess paint falling outside the left and right edges of the paint curtain fall about straight down the faces of the guide plates leaving a region of those faces dry adjacent the paint curtain. A highly uniform thickness of the paint curtain is realized permitting the attainment of thinner paint curtains having a high resistance to tearing. This system and method are especially advantageous in making thin ceramic dielectric layers in the production of monolithic ceramic capacitors.
