Abstract
In apparatus for producing bag packages and including a shaping mandrel presenting a shaping surface and a longitudinal seal forming device for forming a panel of sealable material into a tube and transverse sealing jaws and severing blades for dividing the tube into individual bags, the mandrel includes members defining two carriages mounted at diametrically opposite sides of the mandrel and forming at least in part the shaping surface of the mandrel, and there are further provided clamping members each mounted to face a respective carriage and to be moved toward the shaping mandrel to press the tube against the carriages and thus clamp the tube, and elements connecting the carriages and clamping members together for movement in unison in the longitudinal direction of the mandrel.
