Date Mar. 14, 1996Method and apparatus of forming an air laid paper web. Superabsorbing powder is introduced at an intermediate stage between the initial supply of the fibers to the air laying unit and the final formation of the web. A first coarse distribution of the powder is effected in a compulsory manner, independently of the initial supply of fiber material while the final distribution of powder is effected by means of the same air flows which cause the final distribution of the fiber material for forming the even web layer. In this manner the powder is effectively mixed evenly into the fiber material.
