<p>An aluminum alloy sheet of the AA 6000 series is subjected to a continuous tension leveling procedure. The sheet is passed through a set of pull rollers and a set of brake rollers and subjected to a longitudinal tension between the two roller sets (18a, 18b). Also while travelling under longitudinal tension between the two sets of rollers (18a, 18b), the sheet is subjected to bending and reverse bending over a series of small rollers at a wrap angle in the range of about 0 to 12°.</p> |
