Abstract

In treating a fibre web between the forming section and the drying section of a paper machine, utilizing so-called closed conduction, there are three press nips N1, N2 and N3. A transfer felt 30 is detached from the web W after the second press nip N2 and conducted to a felt conditioning means 33. The fibre web W is transferred on the surface of a smooth central roll 61, to the third press nip N3 between the roll 61 and a recessed-surface roll 71. The transfer felt 30 is conducted from the felt conditioning means 33 to said third press nip N3 and then detached from the web W and conducted through a second felt conditioner 34a/34b back to be adjacent to a return roll 25 within a forming fabric loop 20. There are only two press felt fabrics 30 and 40, whereof the felt fabric 40 encloses a recessed surface press roll 41 and serves as a water- deceiving felt in the first press nip N1 and has a felt conditioning means 43. <IMAGE>
