Abstract (en)
[origin: WO2016020851A1] A method for producing a sound-deadening and/or thermally insulating insert (1) that can be installed in a vehicle; the method comprises the steps of providing a forming casing (5) having at least one outer perforated wall (8) and comprising an inner seat (7) shaped according to the shape of the insert (1) to be produced; providing, on the outside of said forming casing (5), punching needles (13) structured to pass through a skein of fibres; arranging a given amount of fibres (F) inside the seat (7); making said punching needles (13) penetrate into the casing (5) through said perforated wall (8) to cause localized displacements on the fibres (F) inside the seat (7) in order to interweave/twist the fibres (F) together and join/compact them.
