Method of laying panels
InactiveUS6546691B2Increase displacementAvoid the needRoof covering using tiles/slatesWallsEngineeringMutual position
The present invention provides a method of laying and mechanically joining panels, especially floor panels. In a first step a first panel is already located in a first row. A second panel is positioned in a second row in a first position in relation to the first panel. A third panel is now brought into the second row and into the first position in relation to the first panel. In this position, there is a mutual distance between the adjacent edges of the second and third panel. In a second step the second and third panel are angled into the third mutual position in relation to the first panel. Thereby, the second and third panel each achieve the possibility of easy displacement in the third direction in relation to the first panel. In a third step one or both of the second and third panel are moved in relation to the first panel. By this displacement the second and third panel get in a second position in relation to each other. An additional intermediate step may be employed between the first and the second step. In this intermediate step the second and third panel are angled down into the second mutual position in relation to the first panel.
