Abstract (en)
[origin: US5535610A] The cross bowing in metal strip, especially thin metal strip of a thickness less than 2 mm, is removed by providing downstream of the high tensioned section of the strip at which stretch leveling or stretch bend leveling is effected at least one correcting roller which has an adjustable depth of penetration into the path of the strip at a low tension section, the depth of penetration being controlled by measuring the cross bowing also in the low tension section.
