Method of making a floorboard and method of making a floor with the floorboard

A method for making a floor of mechanically locked floorboards, each of said two different types of floorboards along their four edge portions having pairs of opposing connectors for locking adjoining first type and second type floorboards in both a vertical and a horizontal direction,

• the connectors of the first type and second type floorboards designed to allow locking-together in a first direction in a plane of the floorboards by at least snapping-in and locking-together in a second direction in the plane of the floorboards by inward angling and/or snapping-in, and
• the first type floorboard differing from the second type floorboard because the connector of the first type floorboard along one pair of opposite edge portions is arranged in a mirror-inverted manner relative to a corresponding connector along the same pair of opposite edge portions of the second type floorboard,
• the method comprising:
• (a) locking together a short side of a first floorboard with a long side of a second floorboard, the first floorboard being of the first type floorboard and the second floorboard of the second type floorboard;
• (b) locking together a first edge portion of a third floorboard with a long side of one of the previously connected first floorboard and second floorboard and displacing said first edge portion of the third floorboard along the same to locking-together by snapping in a second edge portion of the third floorboard with a long side of the other of the previously connected floorboards;
• and
• (c) repeating step (b) to add further floorboards.
