Abstract (en)
[origin: WO2022003646A1] A correction apparatus for correcting the planarity of a metal strip (1 ) advancing into a coating system for coating said metal strip with a layer of molten metal, said apparatus comprising - a bridle roll (2), which modifies the feeding direction of the metal strip (1) exiting an annealing furnace (10); - only one sink roll (3), arranged downstream of said bridle roll (2) and inside a tank (11) adapted to contain a bath (12) of said molten metal; - a correction device (4) for correcting the planarity of the metal strip arranged between said bridle roll (2) and said sink roll (3); wherein said correction device (4) comprises at least two motorized rolls (5, 6); wherein a first motorized roll (5) of said at least two motorized rolls is distal from said bridle roll (2) in a fixed position with respect to a feeding path of the metal strip (1), said first motorized roll (5) being arranged on a first side of said feeding path; wherein said bridle roll (2) is also arranged on said first side; and wherein a second motorized roll (6) of said at least two motorized rolls is proximal to said bridle roll (2) and movable along the direction of the strip thickness, said second motorized roll (6) being arranged on a second side, opposite to the first side, of said feeding path.
