Abstract:
A method for producing a sound-deadening insert of a silencer of an exhaust-gas discharge system in an internal-combustion engine of a vehicle; the method comprises the steps of providing a mattress made up of continuous voluminized fibers of sound-deadening material, and needling the mattress so as to cause a compacting/interweaving of the fibers in order to obtain compacting lines.
