Abstract
In order to be able to realize complicated jaw movements in a device for welding of a foil tube, comprising two welding jaws, which can be moved opposingly and clamp the foil tube between one another, whereby a linear motor is provided as the jaw drive, it is suggested that the gearing houses a cam plate connected to a movable part of the linear drive, that the cam plate has two separate curves, and that each one cam connected to a jaw carrier is guided along a curve.
