Abstract: A creping blade for creping a cellulosic web from a rotatable cylinder in a creping process includes first and second side faces. The first side face is at least substantially opposite to the second side file. The blade also includes an upper surface adjacent to the first and second side faces. A plurality of notches is provided along the upper surface. Each of the notches has a bottom portion and an open end defined by at least a portion of the upper surface. The notches are configured to increase the caliper of the cellulosic web when the creping blade crepes the cellulosic web from an outer surface of the rotatable cylinder. Creped paper and improved methods of manufacturing paper are also provided.

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.

Abstract translation: 本发明是一种在压榨压区中从吸收性纤维网中最大限度地除水的方法。 本发明使用具有空隙体积的毯子的挤压单元，并且具有最大限度地提高造纸机的压榨部分或扬克烘缸中的除水量的压力分布。 根据本发明的按压单元的压力分布在压力分布曲线的出口处和/或之后具有非常陡峭的压降，以便通过最小化纤维网的再润湿来最大限度地减少水分。 根据本发明的改进的压力分布导致增加的除水和/或改善的线速度。 空隙体积进一步增加除水量和/或提高线速度。
