摘要： 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.

摘要： 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.
摘要翻译：从纤维配料制造片材的改进方法包括：将配料沉积在多孔载体上; 紧密地脱水配料以形成新生网; 在加热的圆筒上干燥网; 从其起皱并通过将幅材干燥成成品。控制幅材的微观结构以促进干燥。当通过薄片的气流的特征在于小于约1的雷诺数时，该产品具有4至10的特征通过干燥系数。本发明的新产品的特征在于湿回弹比，水力直径和内部粘合强度参数。

摘要： 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. The stepped creping blade used in carrying out the process of the present invention includes an elongated body adapted to be engagable against, and span the width of, the moving surface, the elongated body having a cross section including a relief surface generally facing toward the moving surface, a back surface substantially parallel to the relief surface and generally facing away from the moving surface, a top surface adjacent both the relief surface and a recessed surface with the recessed surface being adjacent both the top surface and the back surface and forming a contact edge with the top surface such that the contact edge engages against the moving surface for creping the cellulosic web from the moving surface. The top surface and the recessed surface form a back step edge while the recessed surface and the back surface form a trailing edge. When utilizing such a blade configuration, the process further includes the steps of first contacting the cellulosic web conveyed by the moving surface with the contact edge, then optionally contacting the cellulosic web creped by the contact edge with the back step edge and subsequently contacting the cellulosic web creped by the contact edge with the trailing edge.
摘要翻译：提出了一种用于生产起皱片材以及由这种刀片形成的起皱刀片和起皱纸制品的方法，该方法包括以下步骤：将纤维素纤维网粘附到移动表面，提供设置成绉纤维素的阶梯式起皱刀片来自活动表面的纤维网和从移动表面起皱纤维素网形成具有比预先制备的起皱纸产品更大的本体和吸收性的起皱纸产品。在实施本发明的方法中使用的阶梯式起皱刀片包括适于可接合并跨越移动表面的宽度的细长主体，细长主体具有横截面，该横截面包括通常面向移动表面，大致平行于所述浮雕表面并且大体上背离所述移动表面的后表面，邻近所述浮雕表面和凹入表面的顶表面，所述凹表面与所述顶表面和所述后表面相邻并且形成触点边缘与顶部表面接触，使得接触边缘抵靠移动表面接合，以使纤维素网从移动表面起皱。顶表面和凹面形成后台阶边缘，而凹面和后表面形成后缘。当使用这种刀片构造时，该方法还包括以下步骤：首先使由移动表面传送的纤维素纤维网与接触边缘接触，然后任选地使由接触边缘起绉的纤维素纤维网与后台阶边缘接触，随后使纤维素纤维网通过与后缘的接触边缘起皱。
