Abstract
Method and apparatus for spreading pulp of a consistency of 6 - 15 % to a web. Pulp discharged from the feed chamber of a head box through a space between a rotating roll (22) and a wall of the feed chamber (21) is supplied onto a web forming device (20) whereby a high energy content fluidizes the pulp in a space (23) and the pulp is evenly distributed to a web onto the web forming device (20).
