METHOD FOR THE MANUFACTURE OF A MULTILAYER WEB
The invention relates to a method for the manufacture of a multilayer paper or board web containing recycled fiber. The method comprises forming the multilayer web of at least two layers having stock compositions different from each other and diluting the pulp suspension in the formation of each layer with wire water into headbox consistency and feeding it by means of a headbox to a wire section, where the web is dewatered, and joining these layers to form a multilayer web. The method also comprises the step of passing the wire water removed from the wire section in the forming of each layer to be used in the dilution of a pulp suspension, to be fed, of another layer.
