<p>A floorboard (10), such as e.g. a parquet element, has a first edge provided with a tongue (24) and an opposite, second edge provided with a groove (18), the tongue (24) and groove (18) fitting into corresponding grooves and tongues of further similar floorboards. The groove (18) has a stepped profile, which is configured so that the back end of the groove (18) is narrower than its entrance. The tongue (24) has a stepped profile substantially matching that of the groove (18). <IMAGE></p> |
