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.
Claims7
A method for producing a sound-insulating floor covering having a multilayer insulation device, wherein the insulation device extends along a longitudinal direction, a width direction and a thickness direction, and the insulation device has different acoustic, mechanical or physical properties in at least one of said directions, said method comprising the steps of:
- (a) providing an insulation device comprising a coupling layer having a floor contacting layer in a form of a flocked fiber layer thereon;
- (b) transporting the insulation device with the flocked fiber layer from step (al into a steam/vacuum tool and applying steam from an underside of the insulation device;
- and
- (c) cooling, cutting and positioning the insulation device from step (b) to fit in a motor vehicle.
