Method for producing a fibrous mat for the acoustic and/or thermal insulation of a component of a motor vehicle

Abstract

Method for producing a fibrous mat, which can be installed in a component of a vehicle provided with an internal combustion engine for acoustically and thermally insulating the component. The method comprises the steps of: providing a fibrous core consisting of at least one fibrous bundle that extends along a direction that is approximately parallel to a longitudinal axis; wrapping the outer surface of the fibrous core by means of a fibrous bundle that extends along a direction that is approximately transverse to the bundle of the fibrous core, thus providing at least one outer tubular fibrous containment sleeve that extends, in turn, along the longitudinal axis and covers the outer surface of the fibrous core to trap the fibrous core therein.
