Abstract:
1. Method for checking the adjustment of a flattener under traction which is to flatten a metal strip, of the type comprising a frame ( 1 ), frame uprights ( 8 ) and two stacked cassettes ( 2 , 3 ) each supporting a plurality of rollers ( 4 ) between which the metal strip ( 5 ) passes, characterised in that a quantity representing the angular position of the cassettes ( 2 , 3 ) relative to the direction of movement of the strip ( 5 ) is measured and, when necessary, the angular position of the cassettes is corrected in order to cause it to comply with a predefined angular position, wherein said quantity representing the angular position of the cassettes ( 2 , 3 ) relative to the direction of movement of the strip ( 5 ) is constituted by the lateral forces, generated by the rotation of the rollers ( 4 ), on the cassettes ( 2 , 3 ).
