  • Publication number: 20080035289
    Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.

  • Publication number: 20070107863
    Abstract: An improved process for making sheet from a fibrous furnish includes: depositing the furnish on a foraminous support; compactively dewatering the furnish to form a nascent web; drying the web on a heated cylinder; creping the web therefrom and throughdrying the web to a finished product. The microstructure of the web is controlled so as to facilitate throughdrying. The product exhibits a characteristic throughdrying coefficient of from 4 to 10 when the airflow through the sheet is characterized by a Reynolds Number of less than about 1. The novel products of the invention are characterized by wet springback ratio, hydraulic diameter and an internal bond strength parameter.

  • Patent number: 6066234
    Abstract: A process for producing a creped sheet as well as a creping blade and creped paper product formed by such blade is set forth with the process including the steps of adhering a cellulosic web to a moving surface, providing a stepped creping blade disposed to crepe the cellulosic web from the moving surface and creping the cellulosic web from the moving surface forms a creped paper product having greater bulk and absorbency than previously prepared creped paper products.
