<p>What is described is an apparatus for welding the sealing joint (23) on a package (24) consisting at least partially of plastic-coated paper, with a welding tool having jaws (25, 28) and counterjaws, with a mounting and with a drive device (1) for generating the pressure force. …<??>So that two welding tools (25, 25a) are employed and actuated simultaneously and essentially identical pressure forces are available at the two work stations, according to the invention two welding jaws are each fastened on an outer hollow shaft (7, 9) so as to be rotatable on a common axis (2), each outer hollow shaft (7, 9) is connected (at 14; 16, 17) fixed in terms of rotation to a common torsion-bar spring (3) as part of the drive device (1), and the torsion-bar spring (3) is driven from outside (at 11, 12). …<IMAGE>… </p> |
