Beschreibung
Zusammenfassung:	The fourdrinier section (10) of a papermaking machine, for the prodn. of a multi-layer fibre web, has a double fourdrinier section (20) to form the second layer which is before the point (42) where the two layers are brought together, in the direction (14) of blanket (12) travel. The second layer on the first fourdrinier (22) is brought into the junction section (42) at an angle (44) against the blanket (12) ≤ 90 degrees . Also claimed is an operation where the second layer is formed in a zone in front of the layer junction point (42). The second layer is brought by the first fourdrinier (22) to the layer junction point (42) at an angle (44) ≤ 90 degrees to the blanket (12).
