Abstract
The invention relates to a former-press section ( ) of a paper machine and to a method of transferring a web from a former to a press section. Between the former section ( ) and the press section ( ) there is a pre-press zone (PP) which removes water from the web (W) and through which the web (W) is passed as a closed draw from the former section ( ) to the press section ( ). The upper wet wire ( ) or the equivalent transfer wire ( A) of the former section ( ) is passed through the pre-press zone (PP), the web (W) being passed on the lower face of said wire into and through the pre-press zone (PP). Inside the loop of the upper wet wire ( ) or of the equivalent transfer wire ( A) and/or inside the loop of the lower wet wire ( ) there are transfer devices ( ) based on the use of a pressure difference. The transfer devices ( ) are arranged to operate in connection with threading or an operational malfunction such that the web (W) is separated from the upper wet wire ( ) or the equivalent transfer wire.
