Abstract
A floorboard (1), which along one long side has a female connecting means (2) and along its other long side has a male connecting member (4), is made of a raw board (18), which is substantially rectangular in cross-section. The raw board (18) has a carrier layer (14, 15) and, applied thereto, a wear layer (16). The raw board (18) is first subjected to limited profiling, which comprises the step of the surface layer (16) being provided with longitudinal edge bevels (17). After that, the surface layer (16) provided with edge bevels (17) is varnished. Finally the raw board (181) is subjected to final profiling intended for finishing of the connecting member (2, 4) and comprising the step of a downward and laterally open longitudinal recess (13) for receiving a connecting part (10) of the female connecting member (12) of another floorboard being formed under a connecting part (12) of the male connecting means (4).
