CONTROLLED PROFILE DRYING HOOD

摘要

Apparatus is disclosed to control a Yankee hood profile along the cylinder wrap so as to provide a structurally stable hood having controlled impingement distances at operating temperatures. Radial support of the hot hood internals are located at or near the extremities of the hood wrap and the internal profile along the cylinder wrap is on an adjusted cold shape so that the profile is even when operating temperatures are reached. Thus, the hood is "deformed" (not prestrained) when cold but, when the operating temperature is reached, it assumes the desired configuration.
