Abstract
A tissue paper making machine, a tissue paper product, and a method for producing such a tissue paper product. According to the invention, a dewatering and sheet-forming wire (13;14) is deposited in the pulp flow area by a texturing wire (16;17) that is provided with a texture comprised of closed wire zones. This results in the production of a tissue paper product having improved optical and haptic properties.
Claims14
A tissue paper machine comprising a head box section, a dewatering and sheet-forming section, and a drying section;
- wherein an outer and inner dewatering and sheet-forming wire in the head box section or in the sheet-forming section is backed by a texturizing wire having dewatering wire zones and closed wire zones.
A method of producing a tissue paper product, comprising the following steps:
- depositing a fiber stock suspension on a dewatering and sheet-forming wire backed by a texturing wire having dewatering wire zones and closed wire zones;
- inhibiting or strongly restricting dewatering by the dewatering and sheet-forming wire in the Z direction via the closed wire zones;
- and
- boosting the concentration of fibers in the dewatering wire zones of unrestricted dewatering.
