<p>The invention relates to a sound-insulating floor covering, in particular for motor vehicles, comprising a carpet layer ( 2 ) which on the underside comprises a base substrate ( 3 ), and a sub-layer ( 8, 9 ) which is bonded to the underside of the carpet layer by means of a hot-melt adhesive ( 5, 6 ) which is applied in multiple stages. In order to economically produce such a floor covering which is light in weight, has good sound-insulating qualities and adequate rigidity, it is proposed that directly to the base substrate of the carpet layer ( 2 ) a hot-melt adhesive ( 5 ) is applied which has an average mass flow rate of the melt ranging from 190 to 210 g/10 min and has a lower melting point than a hot-melt adhesive ( 6 ) which is applied in a subsequent stage and has an average mass flow rate of the melt ranging from 140 to 160 g/10 min. Furthermore, the second hot-melt adhesive ( 6 ) can preferably comprise hollow mineral microbodies ( 7 ). Moreover, a method for the production of such a floor covering is described.</p> |
