  • Roller folding head
    Patent number: 7152292
    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.

  • Roller folding head and method for folding a flange
    Publication number: 20050015955
    Abstract: 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°. One pair of rollers is provided for each step, at least two thereof being arranged on a roller folding head.
