  • Patent number: 4288476
    Abstract: Improved method 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. The method includes moving a metal strip, supported by a deflector roll having a width less than that of the strip, in an arcuate path through a bath of molten coating metal with the side of the strip to be uncoated contacting the deflector roll. To prevent coating of the strip, a stream of gas is directed toward the edges of the side of the strip contacting the roll which project beyond the roll and against the surface of the bath.

  • Patent number: 4207831
    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.
