ABSTRACT:
The invention pertains to apparatus for thermally insulating selected portions of a cylindrical dryer drum, usually adjacent the drum ends, for the purpose of obtaining a substantially uniform drum shell temperature throughout its length to obtain a uniform moisture profile throughout the width of the web being dried. A plurality of cylindrical segments are bolted together within the drum interior to define a circumferential assembly biased against the drum inner surface. The segments each include a thermal insulation material engaging the drum shell preventing direct access of that engaged portion of the shell with the steam within the drum thereby reducing the exterior temperature of the drum shell at the location of the thermally insulated segment. The segments may be bolted together, widthwise, to increase the axial dimension of the temperature controlling segment assembly.
