Abstract
A system for applying heat to wet coatings applied to selected areas on a front surface of a continuous substrate includes an energy emitter for applying energy to the substrate to heat the substrate, a metallic roll contacting a back surface of the substrate opposite the front surface being heated, a mechanism for advancing the continuous substrate over and around the metallic roll and a contact member having a surface engaging the surface of the substrate. The metallic roll conducts heat away from non-selected areas on the substrate while the substrate is heated to prevent overheating of the non-selected areas. The contact member engages a surface of the substrate so that the substrate is in contact with greater than 180.degree. of the metallic roll.
