摘要

A sheet blank (10) can be moved through between a first and a second bending roll (24, 25). Arranged behind the bending rolls (24, 25) in the direction (12) of motion of the blank is a deflector (28), at which the sheet blank (10) can be deflected away from the first bending roll (24) out of its original direction (12) of motion and around the second bending roll (25). To intercept the forward edge of the sheet blank (10) in the original direction (12) of motion, an intersecting strip (29) is arranged at that side of the second bending roll (25) which faces away from the first bending roll (24), at least approximately in the common plane of the axes of the two bending rolls (24, 25). The intersecting strip (29) is part of a guide rail (30), along which the rounded sheet blank (10) is guided with the longitudinal edges close together during an axial onward movement. The guide rail (30) extends at least approximately over the entire length of the two bending rolls (24, 25) and is arranged in such a way that the sheet blank (10) surrounds it during the bending of the latter. …IMAGE…
