摘要： This invention relates to a machine for the production of a tissue paper web with a forming section in which the tissue paper web is formed from a pulp suspension on a skin and with a nip which is formed between the cylindrical surface of a drying cylinder, in particular a Yankee drying cylinder, and a mating surface and through which the tissue paper web can be conveyed together with the skin. The configuration of the machine is variable such that, depending on the quality of the tissue paper to be produced, for example its absorbency or tear resistance, the skin is either a three-dimensionally structured skin, a structured mesh, a non-structured skin, or a felt, whereby the mating surface is formed by the cylindrical surface of a press roller which includes a suction zone and in which provision is made for bores communicating with the suction zone.

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 relates to an improved process for producing chemical cellulose pulp wherein biopolymers are added immediately before, during or after a bleaching step, depending on pulp characteristics and on process conditions used. The biopolymers according to the present invention are starch by an etherification reaction. This treatment results in a differentiated pulp having improved physical, chemical and mechanical properties when compared with cellulose pulps obtained by traditional processes. The use of said biopolymer alters the relations between important pulp properties rendering their application in papermaking process advantageous. This differentiation increases the possibilities of use and also of new applications, including for the substitution of pulps produced from other cellulose sources. Thus, the present invention also relates to a process for the preparation of paper, such as printing, writing, decorative, special or tissue-type papers, through the use of the cellulose pulps modified by the above process.
