ABSTRACT:
This machine includes a feed device (13) through which a metal element (1) to be curved is advanced with a stepped feeding movement. A bending device is situated downstream and in the vicinity of the feed-device outlet. The bending device can be rotated about a first axis perpendicular to the feed direction and about a second axis parallel to the feed direction, and can also be reciprocated parallel to the first axis. Preferably the bending means thus rotate about the metal element (1), which is secured against rotation.
