Abstract
Disclosed is a floor covering insulation for a motor vehicle with a multi-layer, preferably flocked, fibre insulation which, by a soft/smooth coupling layer to the wear surface, realises a sound insulation floor covering with improved acoustic and mechanical-physical properties, with a simultaneous reduction in weight if possible. Also disclosed is a method for manufacturing the sound insulation.

1-12. (canceled)
A method for producing a sound-insulating floor covering with a multilayer insulation device, wherein this insulation device extending along a longitudinal direction, a width direction and a thickness direction, and this insulation device having different acoustic and/or mechanical-physical properties in at least one of these directions, wherein this floor covering having a material structure which has at least one nonwoven element and at least one film element,
- wherein
- a fibre layer facing a motor vehicle floor in an installed state is flocked in a flocking device and at least this fibre layer is transported into a steam/vacuum tool and a binder present in the insulation device is activated by applying steam from an underside of the insulation device towards the wear layer, and furthermore the insulation device is cooled, cut and positioned in a motor vehicle.
