- the beam direction of the headbox 58 associated with the additional gap former 54 corresponds to the running direction of the fibrous web to be formed, i.e. in the present case the running direction LA of the first layer A formed by the wire forming 34.
- the fourdrinier wire 36 starting from the headbox of the fourdrinier wire former 34, is both over the first rubber zone provided in the region of the deflecting roller 28 of the gap former 10 and over the rubber zone 30 in which the layers B and C with their sides higher fines content are littered with each other, and at least substantially horizontally across the additional rubber zone 56.
