Abstract (en)

[origin: WO2009024649A1] Method for compensating for uneven shrinkage in a paper web in the press and drying sections of a paper machine, in which there is at least one open draw. In the method, a flow guide/guides are used in the head box, by means of which the machine direction orientation tendency of the fibres is reduced in the edge areas of the web and the angle of detaching of the web from the centre roll is adjusted, by directing onto the web an air jet that is located in the cross direction and the pressure of which can be adjusted in the said direction.
