An elongated substrate may be heated in a roll processing system. At least a portion of the elongated substrate is loaded into the roll processing system. A sufficient electrical current is caused to flow in the portion of the elongated substrate to heat the portion to a desired temperature. The heating may be either resistive or inductive. The roll processing system may be a roll-to-roll type where the substrate moves as a portion of it is heated. Alternatively, the substrate may be wound into a coiled substrate and the turns of the coil insulated against undesired electrical contact. The entire coiled substrate may then be heated either resistively or inductively.
