Abstract
A device and a method for on-line control of the fibre direction of a fire web (), being manufactured from stock delivered from a headbox () through a discharge opening () defined by movable lips (), while using a fibre direction meter () located downstream and actuating members (), which are allonged long the lips for regulation of the discharge opening as a response to individual control signals, each being a function of measured fibre direction values; wherein a control unit () receives the measured fibre direction values, calculates the control signals, and transmits these to the actuating members. According to the invention, the control unit identifies an array of fibre direction values, originating from positions in the cross direction of the fibre web which correspond to the positions of the actuating members. The control unit then compares the array of fibre direction values with an array of desired fibre direction values.
