Machine for the production of tissue paper |
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. |
