Zusammenfassung:A board machine comprises a forming section where a lower wire loop (11) forms a fourdrinier-wire section (Tl) at the beginning of which is located a forming board (200) which consists of at least one stationary, non-pulsating forming shoe (210). In the forming shoe (210), there is a cover (211) provided with thorough holes (212), setting against the inner surface of the lower wire loop (11). A first headbox (100), which is a multi-layer headbox, feeds a pulp suspension jet onto the forming shoe (210). The board machine further comprises a press section (Pl) where a surface (Wa) of the web (W) having been against the lower wire loop (11) is pressed against a smooth surface, a dryer section (Dl) where the web (W) is dried with at least one cylinder-dryer group and a coating section (400) where at least the surface (Wa) of the web (W) having been against the lower wire (11) is coated.
