Abstract

The invention concerns an arrangement in a paper machine for controlling the lead strip threading R of web W. The arrangement is placed in the area between an intermediate roll 12 in the press section and a separate press nip N4 of the paper machine press section. The separate press nip N4 is formed between an upper roll 25 with flat surface and a lower roll 26 with concave surface. Around the lower roll 26 is a lower felt 17 for the separate press, which lower felt runs from a suction transfer roll 16', 16a on a straight course to the separate press nip N4. Over the said straight course of the felt 17 in question, one or more transverse blow pipes 20 are installed above same, from which pipe(s) blows F1 are directed in a direction opposite to the run direction of the felt 17 and web W. These blows F1 will reduce the induction of air into the cavity K between the said felt's 17 straight course and the wall 21 above it, at the same time encouraging the lead strip R to be held on the surface of felt 17 on its said straight course leading up to the separate press nip N4. <IMAGE>
