ABSTRACT:
A description is given of a device for continuously rolling a sheet-metal strip into a profile with profile limbs of straight cross section, in particular for producing longitudinally welded rectangular tubes specifically with the aid of former rolls (13) which are arranged on both sides of a central plane (2) running in the longitudinal direction of the strip and are mounted in a separate frame (11, 12) in each case together with counter-rolls (14) which are aligned perpendicular to the central plane (2) and can be adjusted perpendicular to the central plane (2). In order to create advantageous design conditions, it is proposed that the frames (11, 12) are arranged on each side of the central plane (2) with the associated counter-rolls (14) respectively opposite the neighbouring frames (12, 11) on the opposite side of the central plane (2) in a fashion offset in the longitudinal direction of the strip.
