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.

Abstract: A clamping device for a motor vehicle production line has, on both sides of a transport apparatus for rough car bodies, ways on a common base frame leading underneath the transport apparatus for one side carriage each which can run separately on one side of the transport apparatus. The side carriage bears only the side members of one side of the transport apparatus. Clamping means serve to connect the side carriages with the base frame whenever the side carriages are in the working position.
