The invention is a new machine for the coupling of webs, to be used for the production of not woven fabrics. The edge of a belt travels orthogonally to the motion of the collection belt, in such a way as to lay more layers of webs onto the first layer. The travel of the webs to be laid down is such as to guarantee a product with constant characteristics.
