<p>A board machine for manufacturing a multilayer cardboard web (1) with a printable surface layer (2), comprising a press section (5) with at least one double-felted press (45) and a wet section (4) with a first forming unit (7) for forming a first layer (2) and one or more further forming units (8) for forming one or more further layers (3). In accordance with the invention, the first forming unit (7) forms the printable surface layer (2) and, with its forming wire, transfers the web (1), which is couched by several layers (2, 3), to the upper press felt (49) with the surface layer (2) facing downwards in the press nip to contact the lower press felt (52), which exerts a greater adhesion force on the web than the upper press felt and which encompasses the lower press roll (48) by a pre-determined minimum sector angle. The invention also relates to a method for manufacturing a multilayer cardboard web by means of such a board machine.</p> |
