An amendment to an abstract is also provided herein. The changes are minor in nature, and, as such, a replacement abstract with markings to show all changes relative to the immediate prior version, is attached hereto.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority under 35 U.S.C. §119 of German Patent Application No. 10 2004 011 531.1, filed on Mar. 8, 2004, the disclosure of which is expressly incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a wooden material board, in particular a flooring panel, having a tongue formed on at least one side edge and a groove formed on the opposite side edge, and a top side and an underside. [0004] 2. Discussion of Background Information [0005] Flooring panels having a wooden material supporting board are normally designated laminate panels and have been on the market for many years as a substitute for parquet. The desired pattern (parquet, wood grain, tiles and so on) is printed onto a paper web, which is then coated with resin and rolled up onto a roll. The decorative web prefabricated in this way is placed on the supporting boar...

AI Technical Summary

Benefits of technology

[0011] As a result of this configuration, first of all the paper layer is eliminated. Consequently, the pattern can change neither in length nor in width. The saw with which panels are later cut to size can be preset. By means of the elastic varnish layer which is applied directly to the pattern, footfalls are damped, so that the footfall characteristics are improved. The harder varnish layer applied to the elastic varnish layer prevents wear caused by abrasion or damage to the surface.

[0012] Corundum particles can be scattered in the second varnish layer, in order to increase the abrasion resistance of the flooring panel.

[0014] The varnishes of the varnish layers are preferably UV-curable, which means that the fabrication times are shortened.

[0017] If the tongue and the groove are provided with locking means which prevent displacement transversely with respect to the joining direction in the case of two panels joined to each other, the flooring can be laid in a floating manner without glue.

Problems solved by technology

Even if such jumps in the decoration only amount to a few millimeters, they stand out when viewed, which has a detrimental influence on the esthetic impression and therefore reduces the quality of the laid floor.

Manual setting is very complicated.

The soundproofing qualities of laminate panels are poorer as compared with parquet.

Secondly, applying the insulating layer to the underside of the supporting board requires a further operation and additional material, which increases the manufacturing costs.
