发明名称 Former and process for producing a tissue web
摘要 A former for producing a tissue web and a process of making a tissue web using the former. The former includes a forming element, an inner dewatering belt, and an outer dewatering belt. The inner and outer belts converge to form a stock inlet nip. The inner and outer belts are guided over the forming element and thereafter separating from one another in the area of a separation point. At least one suction element is positioned adjacent the inner belt on a side which is opposite the outer belt. Alternatively, a conditioning device is positioned adjacent the outer belt. The process includes forming the tissue web in the area of the forming element, guiding the inner and outer belts around the forming element, and separating the inner and outer belts in the area of the separation point. Alternatively, the process includes conditioning the outer belt.
