Abstract

The invention relates to a method to, in connection with the preparation of a web which to an essential part consists of cellulosic fibres, improve the formation of the web material in a one or plural wire machine by, to an essential part, dispersing existing flocks in the stock which is led from an inlet box out onto at least one wire, and to counteract the reformation of flocks in the stock on the wire. The distinguishing feature is that ultrasound energy is furnished to the stock in at least one wire section. The invention also relates to a device for performance of the method.
