Abstract:
A paper machine for manufacturing a continuous paper web, comprising:a wet section;a press section including a double-felted press having a first press member and a second press member defining a nip therebetween, a first press felt arranged to travel in a loop through the press nip and around a first guide roll located downstream of the press nip, and a second press felt arranged to travel in a loop through the press nip and around a second guide roll located downstream of the press nip, the guide rolls being located in relation to each other such that the press felts normally diverge from each other after the press nip;a treatment unit located downstream of the double-felted press for increasing the dry solids content of the web, wherein the web during normal operation traverses an open draw downstream of the press nip and upstream of the treatment unit; anda web control system activatable upon a rupture of the web in said open draw so as to exert force on the web to prevent the web from adhering to and traveling with the first press felt beyond the first guide roll such that the web downstream of the first guide roll travels on the second press felt.
