The invention relates to a vertical bagging machine (), equipped with a first linear motor () for displacing a transversal seal unit () in a first direction, preferably vertically (), and a second linear motor () for executing a displacement in a second direction, preferably horizontally (), in order to displace a heat-sealing jaw () in the latter direction or to cause two heat-sealing jaws () to be displaced against one another by means of a gear (). The linear motors () are interconnected () by means of a cross formation. Each linear motor () consists of a primary part () and a secondary part (). The cross formation () forms a stable connection for the linear motors () that act in displacement directions running perpendicularly to one another

Vertical bagging machine comprising two linear motors

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.
