ABSTRACT:
A steam heated drying cylinder for machines for making paper comprising a cylindrical shell having inner surfaces thereon. The cylindrical shell includes a center region of substantially uniform thickness, end flanges extending radially inwardly of the center region, and transition regions between the center region and end flanges. The transition regions have inner surfaces that taper radially outwardly from the end flanges toward the center region. An insulation layer is disposed on the inner surfaces of the transition regions so as to provide substantially uniform drying along the width of the paper being made.
