FIELD: construction. ^ SUBSTANCE: system to connect panels as boards has two long and two short edges with retaining shapes arranged on edges, which in the joined condition form a geometric closure. Retaining shapes on long edges and/or short edges have at least one surface, which interacts with the coupled surface, when retaining shapes are joined with each other, and besides at least a surface or a coupled surface has a layer with a higher friction coefficient that increases friction. The layer that increases friction is formed as a layer produced by flocking, and includes the main layer and short fibres, which with a closed end are fixed in the main layer, and with a free end they go out from the main layer, at the same time short fibres have an angle of inclination to the insert direction. ^ EFFECT: higher joint reliability. ^ 16 cl, 7 dwg |
