Abstract (en)
In a method for formation of a mat containing different fibre types, a mixture of different fibre types is deposited by an air flow to form a mat. Fibres are fed at two or more successive feeding points (A, B) to the same air flow (F). Turbulence is generated in the air flow for mixing the fibres together uniformly, and the air flow (F) is conveyed to a mat formation point (D). <IMAGE>
