ABSTRACT:
In order to avoid in a tubular bagging machine the disadvantages resulting from the state of the art through a cam-plate control of cross-welding jaws, it is suggested according to the invention, that the control of the movement of the cross-welding jaws occurs in dependency on the contact pressure, the temperature and the needed sealing time, with the drive being able to occur mechanically by means of a toggle-lever drive mechanism.
