Abstract

Process and apparatus for producing a folded seam connection along a joint between cups made of sheet metal having flanges of folded seam connection and forming a workpiece, in particular a vibration damper, wherein at least one folding tool and the workpiece with the folding flanges, which are pressed on each other, are moved relative to one another. The workpiece is rotated around a rotating axis traversing the workpiece in an essentially perpendicular manner with respect to the plane of the joint. The folded seam connection is produced by rolling over the folding flanges once or several times by at least one folding roller. In the plane of the joint, the folding roller can be swung around relative to the workpiece and/or pressed against the latter. The process and the seaming machine offer the option to simply pass over interruptions of the folded seam connections by providing a correspondingly configured guide surface for the folding roller.
