Abstract
The invention relates to a method of draining a fiber pulp suspension, where the fiber pulp suspension is applied to a convergent dewatering space arranged between two wires travelling in the same direction. In the dewatering space, water and powdery substance are removed from the fiber pulp suspension through the wires. Pressure pulses are generated in the fiber pulp suspension along the length of the dewatering space with pressure pulse elements that are on opposite sides of the wires relative to the fiber pulp suspension and in contact with or at a distance from the wires. The invention also relates to an apparatus according to the method.
