摘要

A machine for bending or cambering a profile section (1), wherein the bending means include two bending rollers (6, 7) mounted on a tool holder carriage (10), and a supporting block (15) for supporting the tool holder carriage (10) pivotably mounted thereon about a rotational axis coaxial with one of the bending rollers (6), said supporting block being pivotably mounted relative to the frame (2) of the machine about a rotational axis coaxial with the other bending roller (7). Furthermore, said machine includes indexing means for rotationally interlocking the tool holder carriage (10) and the supporting block (15) or the supporting block (15) and the frame (2), and rotational drive means (31, 33) for pivoting the tool holder carriage (10)/ supporting block (15) assembly or said tool holder carriage.
