Tissue machine

The present invention relates to a crescent former for producing tissue paper, the former comprising a forming section (A), a press section (B) and a drying section (C), wherein the crescent former further comprises a felt fabric () for carrying the stock from the forming nip () of the forming section (A) to the press nip () of the press section (B), and the felt fabric () being configured to carry the stock to the press nip () where the stock is transferred to the drying section (C), wherein further the felt fabric () is configured to be returned from the press nip () to the forming nip () in a return section (D) such that the felt fabric () forms an endless loop, wherein the return section (D) comprises a cleaning station (), of which at least a part is arranged in a negative machine direction (&#x2212;MD) in relation to a center line (R) of the forming roll ().

Crescent former for producing tissue paper

A device for spraying a coating chemical onto a moving surface () of a papermaking machine includes a machine-wide box body () extending in a cross machine direction and defines an internal space configured to enclose part of a spraying equipment () and also defines an elongate opening () facing said moving surface (). The spraying equipment () includes a plurality of spray nozzle members () for spraying coating chemical through said opening () onto the moving surface (), a coating chemical supplying tube () is connected to the nozzle members (), and a plurality of valves () are mounted on the coating chemical supplying tube (), one for each nozzle member (). To make it possible to change a nozzle member () without requiring that the coating chemical supplying tube () has to be pulled out of the box body (), and where the nozzle change can be carried out with less risk for the operator to any danger, the coating chemical supplying tube () with said valves () is located outside of the box body (), and the nozzle members () extend through a wall portion () of the box body () and are mounted to be individually movable axially to permit removal of anyone of them independently of the other ones.
