发明名称 STRUCTURING BELT, PRESS SECTION AND TISSUE PAPERMAKING MACHINE FOR MANUFACTURING A HIGH BULK CREPED TISSUE PAPER WEB AND METHOD THEREFOR
摘要 <p>A structuring layer (60) of a structuring belt (14) for structuring a wet fibrous web (1') in a press section (3) of a tissue papermaking machine for manufacturing high bulk tissue paper (1), said structuring layer having a web-carrying side with a surface (61) for cooperating with the fibrous web, said surface having depressions (63) forming a three-dimensional structure of the surface. According to the invention, the depressions are distributed over the web-carrying side and constitute altogether 20-80 % of the surface (61), said surface including a flat, continuous top surface area (70) between the depressions (63), said top surface area delimiting the depressions, and each depression has a dimension 1 of 0.25-2.5 mm in a first direction in the plane of the top surface area (70), a dimension b of 0.25-2.0 mm in a second direction in the plane of the top surface area (70), said directions being at right angles to each other, a mean depth d of 0.05-0.6 mm and an area a as measured in the plane of the top surface area (70) of 0.3-4.0 mm2. The invention also relates to a structuring belt with such a layer, a press section with such a structuring layer, a tissue papermaking machine with such a press section, a method of manufacturing a structured high bulk tissue paper web in such a tissue papermaking machine, and use of the said belt, as well as a tissue paper web produced in the machine.</p>
