Abstract
A packing and filling machine produces a container by forming web-shaped packing material into a tube, filling the tube with liquid food up to a liquid level, and laterally sealing the tube with a seal jaw and a counter jaw under the liquid level. The machine includes a diagnostic device having a pressure flange above the position of the lateral sealing under the liquid level and including sterilized gas to detect a vibration propagated when the packing material is clamped by the seal jaw and counter jaw and to diagnose the residual quantity of sterilized gas from the vibration thus detected. The packing and filling machine operating at high speed does not damage the external surface or the longitudinal sealing portion of a packing container, and even the forming/lateral sealing pressing from the opposite sides at high speed does not have a tendency to vary or oscillate the liquid level.
