Yankee Dryer

Категория: не задано

A variation of the multiple-cylinder drying section of a papermaking machine consisting a single large, highly-polished, heated metal cylinder used for producing a machine-glazed finish. The wet paper is pressed against the smooth surface of the cylinder and as it dries it takes on a very smooth, glazed surface. Tissue and crepe papers are produced in a similar manner, followed by a further process that imparts softness and creping.
