Abstract
An improved apparatus providing for uniformity of web thickness is disclosed. In one aspect, the apparatus includes a plurality of gap-controlling, thermal energy sources, and in heat-exchange communication with the thermal energy sources, an assembly for compensating for temperature variation proximate to the thermal energy sources and across the apparatus width. The thermal compensating assembly includes a heat exchange jacket, and in combination therewith, a heat-exchanging, working fluid that undergoes a phase change in performing its heat exchange function.
