ABSTRACT OF THE DISCLOSURE A method is provided for producing a machine- glazed, cellulosic sheet which includes the steps of wet-creping a cellulosic web, and compressing and drying the creped, wet web against the smooth, heated surface of a thermal-drying means. A high degree of smoothness is thereby imparted to the web. The average surface rugosity of the smooth and rugose sides of the sheet is an average surface center line deviation of not more than about 0.25 and 0.35 mill respectively. The compression step is preferably conducted at a pressure of at least about 300 pli (53.7 kg/lineal cm).
