A METHOD AND A SYSTEM FOR PRODUCING A MAT OF FIBROUS MATERIAL

摘要

A method and a system for producing a mat (30) of fibrous material, whereby at least one fibre supply unit (10) supplies a fibre (8,9) to a moving surface (19) located underneath the fibre supply unit (10). The fibre supply unit (10) makes a reciprocating rotating movement around an axis (22). The distance between the center of gravity of the fibre supply unit (10) and said axis (22) is less than half the distance between the fibre supply unit (10) and the moving surface (19).
