Title: Apparatus for one side coating of a continuous strip

Abstract: Improved apparatus for the continuous coating of one side only of a metal strip with molten coating metal, more particularly, one side galvanizing of a ferrous metal strip. Characteristics of the invention are (1) an atmosphere controlled entry chute through which said metal strip passes into the molten coating metal, (2) a deflector roll which guides said strip into and out of said molten coating metal, where the width of said deflector roll is less than the width of said strip and said strip is only slightly immersed below the surface of said molten coating metal, (3) movable guide means adapted to shift laterally with corresponding movement of said strip, and (4) gas jets secured to said guide means and directed towards edges of the uncoated surface of said strip projecting beyond said deflector roll to prevent molten metal from contacting said uncoated surface.
