ABSTRACT:
An apparatus for use in a process of continuously coating a metal substrate with an organic polymer composition by providing a polymer stratum including a melt bonding composition in contacting relation with said metal substrate, heating said substrate by means of electromagnetic radiation capable of heating said substrate, and subsequently cooling said metal substrate so as to form a strong interbonding connection between said melt bonding composition and said metal substrate, wherein said apparatus comprises a first means for generating electromagnetic radiation having a frequency in the radio frequency range and a second means for emitting said radiation and in operative connection with said first means. The second means comprises an inductor loop for directing said radiation through said polymer stratum onto said metal substrate, and said inductor loop is shaped to substantially conform with a linear extension of said metal substrate.
