Abstract

The device has a bending tool (5) with bending cheek (12), pressure pad (13), and first roller (17). Instead of the pressure pad, a second roller (60) can be moved into active position opposite to the bending cheek. In this position, the roller rotates about an axis parallel to the pivot axis (18) of the bending cheek. A third roller (26) rotates about an axis parallel to the pivot axis, on the side of the conveyor track (3) away from the second roller. This roller is moved at right angles to that track, from an original position below the track into a lockable working position above it.
