(85) In one embodiment, the method includes the step (Y1) when the steps (T1) and (U1) are used in the method: (Y1) positioning the first carrying material atop a second carrying material, wherein the second carrying material includes a plastic which is present in a woven or nonwoven, such that the compressing step changes the second carrying material into a second carrying layer which a glue layer bonds to the first carrying layer.

(86) In a further embodiment, the method includes the step (Y2) when the steps (T2) and (U2) are used in the method: (Y2) positioning the first carrying material beneath a second carrying material, wherein the second carrying material includes a plastic which is present in a woven or nonwoven, such that the compressing step changes the second carrying material into a second carrying layer which a glue layer bonds to the first carrying layer.

(87) In a further embodiment, the free surface of the second carrying layer may be further processed. A plastic may preferably be applied to this surface in a known manner, preferably by in situ spraying. This plastic is preferably selected from acrylic-butadiene-styrene copolymers, styrene-acrylonitrile copolymers, acrylate-styrene-acrylonitrile copolymers or two or more thereof. The second carrying layer may prevent the ingress of this plastic into the first carrying layer or even into the decorative layer.
