PURPOSE:To readily obtain a web having a uniform thickness by blowing the second air stream on pulp fibers blown out with the first air stream to collide with each other and disperse the pulp fibers, and accumulating the dispersed pulp fibers on a net. CONSTITUTION:Pulp fibers are blown out with the first air stream flowing in one direction, and the second air stream is blown on the blown pulp fibers to collide with the first air stream, thereby accumulating the dispersed pulp fibers on a net to form a web having a uniform thickness. The coverage of the upper part of the side wall 11a with a pyramid-shaped lid 11b in a dispersing section 10 allows the smooth flow of air in the dispersing section 10 and to provide a web having a uniform thickness. |
