Abstract:
A Yankee Dryer used in drying a web of paper or like materials in which all structural components are fabricated of weldments of steel plate and forgings and in which the outer shell is formed of a weldment of steel plates expanded to roundness and machined to final dimensions. All primary welds are subject to X-ray inspection. The dryer is of lighter weight than the usual cast iron Yankee Dryers, yet designed to withstand substantially higher steam pressure within the shell.
