ABSTRACT Fibre material is defibrated and dispersed in an air flow and introduced through an inlet into a forming head. In the forming head the inlet transforms to a single-curved convex surface, which leads all the way to an accept outlet. A screen is located at adjustable distance from the curved surface for dividing ingoing fibre/air flow into accept and reject. An outlet for the reject is located behind the screen. At a distance of 10-150 mm from the accept outlet a running air-pervious support is located, on which the web precipitates.
