摘要： A sheet manufacturing apparatus includes a web forming unit configured to form a web which includes fibers and resin, and a first pressurizing unit and a second pressurizing unit configured to pressurize the web. The first pressurizing unit has a separation layer, is positioned on an upstream side of the second pressurizing unit in a transfer direction of the web, and is configured to heat the web. The second pressurizing unit is positioned on a downstream side of the first pressurizing unit in the transfer direction of the web, does not have a separation layer, and is configured not to heat the web. The pressurizing force from the first pressurizing unit is smaller than the pressurizing force from the second pressurizing unit.

摘要： A method of producing a tissue paper web in a papermaking machine including the steps of forming the web on a skin, selecting a quality of the web, bypassing a dewatering apparatus, passing the skin and web through a nip and conveying the web to a drying cylinder from the skin. The web is formed in a forming section of the machine from a pulp suspension on the skin. In the selecting step a quality of the web is selected thereby defining a quality selection of absorbency or tear resistance. The bypassing step includes bypassing the dewatering apparatus with the web and selecting a type of the skin dependent upon the quality selection. The machine being configured to bypass the dewatering apparatus dependent upon the quality selection; when the quality selection is tear resistance then the skin is a non-structured skin or a felt and the dewatering apparatus is bypassed, when the quality selection is the absorbency then the skin is a three-dimensionally structured skin or a structured mesh and the dewatering apparatus is not bypassed. In the passing step the skin and the tissue paper web passes through a nip defined between a cylindrical surface of the drying cylinder and a mating surface of a press roller.

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.
