Abstract (en)
[origin: WO03024641A1] The invention relates to a roller folding head. 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 (8, 10; 9, 11 or 20, 22; 21, 23), each pair of rollers (8, 10; 9, 11 or 20, 22; 21, 23) consisting of a pressing roller and a counter roller which interact in order to bend a flange (32) 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 DEG . One pair of rollers is provided for each step, at least two thereof being arranged on a roller folding head.
