Apparatus for coating surfaces

摘要

An apparatus for applying a coating composition to an article and drying the solvent from the so applied coating prior to introduction of the coated article into the ambient atmosphere, comprising a housing or chamber in a generally "J" shape in which the small upwardly turned portion of the "J" defines an inner compartment isolated from the ambient atmosphere by the "J" configuration when the chamber is filled with a volatile solvent vapor and the inner compartment vapors are at an elevated temperature with respect to the remainder of the vapors in the chamber. The apparatus is provided with condensing means at the ambient atmosphere entrance and exit, a source of solvent vapors which may be integral with the chamber, and a means to introduce heat to the vapors and articles when they are in the inner compartment. The apparatus also includes article handling and moving means for transporting articles to be coated into, through and out of the apparatus as well as spray or dip means to apply the coating to the article.
