Abstract
An arrangement for treating a fiber web, in particular for sizing paper and board web (W), using a sizer (10) which has sizing equipment (3, 4) located on both sides of the web (W) and size press rolls (5, 6) located on both sides of the web (W) in between of which a size nip is formed. The web (W) when approaching the sizer (10) is first guided past the size nip of the sizer (10) in a process direction (D) and then is turned into an opposite direction (OD) in relation to the process direction (D) by at least one turning guide roll (15) such that the top side (TS) of the web (W) is sized by sizing equipment (4) located below the web (W).
