    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: A method of making linerboard with elevated CD strength includes: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fibers; b) applying the dewatered web having apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 15 to about 75 percent utilizing a patterned creping fabric. The creping step occurs under pressure in a fabric-creping nip defined between the transfer surface and the creping fabric, wherein the fabric is traveling at second speed slower than the speed of the transfer surface and the fabric pattern, nip parameters, velocity, delta and web consistency are selected such that the web is creped from the transfer surface and distributed on the creping fabric. The fabric-creped web has an elevated CD strength as compared with the web prior to fabric-creping. The process further includes: d) wet-pressing the web after fabric-creping; and e) drying the web.
