REGARDING THE PERIOD OF WELDING OF FRAMEWORK PROFILES (1) AND OF THE BOARDS (2) THE INTERNAL CONTOUR OF THE BOARD FORMED BY THE SHUTTER SKIRT AND THE FASTENING FOOT OF THE BOARD (2) IS COVERED IN THE AREA OF SESGO AND TOGETHER THROUGH AT LEAST ONE PROFILE PIECE ACCORDING TO THE CONTOUR AND ALMOST ACCORDING TO THE CONTOUR AND, AFTER THE JOINT BY WELDING, THE PROFILE PIECE MOVES OUTSIDE THE BOARD AREA (2). IF DURING THE UNION BY WELDING OF FRAME PROFILES AND OF THE JOINTS A PROFILEED PIECE IS USED TO COVER THE INTERNAL CONTOUR OF THE BOARD WHICH IS IN THE AREA OF SESGO, THE CORDON OF WELDING IN THE INTERNAL AREA WILL BE AVOIDED OF THE BOARD, WHAT WOULD HARM THE ELASTICITY OF THE BOARD IN THIS AREA.
