Abstract

La présente invention concerne un procédé de fabrication de feutre pour des fabricants de papier, comprenant les étapes qui consistent à diriger de l'énergie ultrasonique sur le matelas de fibres de sorte que les fibres, au moins partiellement fondues, se trouvent sur une surface du feutre. On imprime ensuite un motif sur le matelas alors que les fibres sont encore à l'état fondu.
