Abstract:
A method for making a tubular member having a continuous and uninterrupted cured elastomeric resin coating on one of two opposed surfaces of the tubular member comprising:forming a continuous vertically extending uninterrupted tubular layer of uncured elastomeric resin; drawing the layer of resin against one of said surfaces of the tubular member to be coated by applying suction below atmospheric pressure between the resin layer and the said one surface of the tubular member to which the resin layer is to be applied while continuously moving the tubular member relative to the continuously formed resin layer with the tubular member generally vertically oriented and in generally coaxial relationship with the tubular layer of the elastomeric resin until said one surface is coated with said uncured resin layer and said layer of uncured resin is adhered to said one surface; and continuously heating and curing said elastomeric resin while it is adhered to the one surface of the tubular member.
