摘要

The panel has a tongue on one side and a groove (3) on the other, whereby several panels can be fitted together. The tongue and groove in cross section are circular, and the width (B) of the groove mouth is smaller than the thickness of the tongue so that the tongue is accommodated in the groove with no play. A slot (5) is formed in the base of the groove and runs at an angle towards the upper or lower side of the panel.
