Abstract (en)
[origin: EP2824252A1] The method of manufacture of metal roofing sheets is characterized by the fact that the unwound metal sheet is moulded from one edge making a system of capillary grooves and small run-off gutters, with a place for the sealing tape, and the extreme edges of the metal sheet are rolled on both sides, and then in the stamping die (5) the modules of transverse outlines of roof tiles are shaped, together with grooves symbolizing side edges of the points of contact of the tiles; and the method of manufacture is automatic with the use of an electronic control system, with the possibility of manual control; the shaped metal roofing sheet is cut off and piled. Flat metal roofing sheet with mouldings is characterized by the fact that it is flat with semicircular ending, with alternately placed outlines of the edges of the tiles with rows mutually shifted by a half of the width of the tile; and on its underside it has a place for a seal (sealing tape) close to the rolled part of the metal sheet.
