It is only important that the connecting device are relatively and the workpieces to be joined relative to each other.
  • the connecting device operates in a direction perpendicular to the workpiece surface and / or in the plane of the workpiece surface. In this way, the connecting device can engage from all sides to the workpieces to be joined, ie laterally and / or from above or below. A combined engagement of the connecting device to the workpieces to be joined is also conceivable.
