ABSTRACT:
An apparatus is disclosed for increasing a transfer of thermal energy through an inner surface of a hollow cylindrical dryer of a papermaking machine to a peripheral outer surface of the dryer. The apparatus includes a plurality of bars of rectangular cross-sectional configuration, each of the bars extending axially within the dryer. The bars are disposed spaced and parallel relative to each other with each of the bars being urged outwardly against the inner surface of the dryer. Also, each of the bars defines an axially extending enclosure.
