ABSTRACT:
The present invention relates to an apparatus for forming fibrous paper or board web on a double wire section of a paper machine. The double wire section includes a first wire loop and a second wire loop. In a first dewatering zone of the double wire section where the paths of both wire loops are substantially linear, the web direction is adjustably deviated towards the second wire loop. In a second dewatering zone located after the first dewatering zone, the web is curved towards the first wire loop to form a curved dewatering zone. In the linear dewatering zone, the second wire loop is loaded towards the first wire loop with wire support members. In the curved dewatering zone, the compression between the wires is effected by adjustably tightening the wires.
