The invention relates to a method and to a device for producing a nonwoven. A starting mixture (4) consisting of particles (3) having different sizes is thrown onto a spill plate (15) by an upper strand (13) of a drag belt (14) in a dosed manner. The spill plate (15) oscillates (28) together with sieve elements (18, 19, 20). Every sieve element lets through a fraction mixture (22, 23, 24) that falls through the lower strand (26) of the drag belt (14) onto a pertaining homogenization device (35, 36, 37), where the fraction mixture is mixed and homogenized. The homogenized fraction mixture is divided up into partial flows (45, 46, 47) by groups of rolls (42, 43, 44) of the homogenization devices, said partial flows being strewn one after the other onto the forming nonwoven (2). |
