Abstract: A composite of sheet metal parts on or for a vehicle comprises a first sheet metal part forming a first outer shell region and comprising a first joining region which projects from the first outer shell region via a bent transition towards an inner side of the composite. The composite further comprises a second sheet metal part forming a second outer shell region and comprising a second joining region which projects from the second outer shell region towards the inner side of the composite, the second joining region facing the first joining region. The composite also comprises a welding or soldering seam along which the sheet metal parts are connected, wherein the seam runs along or alongside a flange edge formed in the first joining region at a distance from the first outer shell region, a flange deviating from the first joining region along the flange edge.

Abstract: A flanging device for roll-flanging a rim of a component includes a flanging head, a first flanging roller which is mounted by the flanging head and can be rolled off on the rim during roll-flanging, and a second flanging roller which is mounted by the flanging head and forms a counter pressure roller for the first flanging roller, the flanging device including a stable protective structure which is or can be fastened to the component and forms a rolling surface for one of the flanging rollers or supports a rolling surface.

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: 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.
