ABSTRACT:
An apparatus for producing liquid-filled bag packages including a tube former for shaping a tube from a strip of packaging material. To introduce amounts of liquid into the end of the tube, a filling tube extends into the tube former with its outlet end having a metering valve. To supply the liquid to the filling tube, the filling tube has, on its end located at the height of the inlet opening of the tube former, a crosswise extending supply fitting, the end face of which is closed with a flexible diaphragm. To actuate the valve, a rod extending in the filling tube is pivotably connected at the height of the supply fitting with a lever, which is pivotably connected to an adjusting cylinder. For pivoting of the lever, the lever has two crosswise arms, which are pivotably connected to connecting rods, the longitudinal axes of which intersect one another in the center of the diaphragm.
