ABSTRACT:
A roller folding head is disclosed. Roller folding heads are used, for instance, when fixing the frame of a sliding roof in an opening in the roof of a vehicle. In order to do this quickly and automatically, the roller folding head is provided with at least two pairs of rollers, each pair of rollers consisting of a pressure roller and a counter-roller which interact in order to bend a flange along a folding line at a specific angle. The folding process is carried out in several stages, one flange being crimped around another flange in a series of partial steps at an angle of 180°. One pair of rollers is provided for each step, at least two thereof being arranged on a roller folding head.
