A clothing for structuring a wet fibre web (') in a press section of a tissue papermaking machine is described which has a three-dimensional woven structure forming elevations () and depressions (), said elevations, like the depressions, are repeated and distributed to form a pattern of polygonal, geometrically similar smallest unitary surfaces (), each of said unitary surfaces having an area a and covering a plurality of depressions with the mean depth d. According to the invention, the area a and the mean depth d of each unitary surface () are adapted in relation to each other in such a way that, calculated by the length unit mm, their ratio is equal to or greater than 30 mm, wherein a is selected within the range of 1.0-3.0 mmand d is selected within the range of 0.03-0.09 mm. The invention also relates to a method for manufacturing a creped tissue paper web by using said structuring clothing.

A soft crepe paper machine comprises a wet section with a press section having a press defined by first and second press elements forming a press nip through which a press felt runs with a paper web. A suction roll is arranged in the loop of the press felt before the press nip at a distance from the second press element, and the felt with the web thereon runs around the suction roll with a large wrap angle. A drying cylinder forms the second press element. The first press element is either a solid press roll, a suction press roll, or a variable crown press roll.
