Abstract (en)

[origin: US2008047314A1] The invention relates to a device ( 1 ) for the continuous lengthening of a metal strip ( 2 ) by traction, said device comprising, in the strip transporting direction (R), at least three S-roll units ( 3, 4, 5, 6, 7 ) each provided with at least two rolls ( 8, 9 10, 11, 12, 13, 14, 15, 16, 17 ). According to the invention, the rolls ( 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 ) are positioned in such a way that the metal strip ( 2 ) is wound round them at a roll periphery angle (a) of more than 180°, and at least the second S-roll unit ( 4 ) in the strip transporting direction (R) comprises two rolls ( 10, 11 ) with different-sized diameters (D<SUB>10</SUB>, D<SUB>11</SUB>).
