Scope and content
The interior Weyerhaeuser's bleached Kraft mill at Longview, Washington, showing paper coming from the air dryer where the sheet of paper is carried around cylindrical driers containing high-pressure steam and the remaining water is driven off in the form of vapor in the air. From the driers the sheet passes through two calendar stacks, each consisting of several steel rolls, riding one on top of the other. The paper passes between them for the purpose of imparting a smooth finish. Further chemical treatment of the surface may also be added on one of these calendar stacks. Ordered by Drew Engineering Company, Portland, Oregon, manufacturers of industrial air systems. (Weyerhaeuser Magazine, November 1952)
