Abstract

There is described a packaging machine (1) for producing packages (2) comprising a conveying device (5) for advancing a web of packaging material (4), an isolation housing (12) having a main chamber (14) and an auxiliary chamber (15), a tube forming and sealing device (16) at least partially arranged within the main chamber (14) and being configured to form and longitudinally seal the tube (3), in use, within the main chamber (14), the tube (3) having a longitudinal seal portion (18), a filling device (17) for filling the tube (3) with the pourable product, a pressure control device (22) configured to control a first pressure (pl) within the main chamber (14) and a second pressure (p2) within the auxiliary chamber (15), a pressure measuring device (23) configured to measure a pressure difference (?p) between the first pressure (p1) and the second pressure (p2) and an analysis unit (24) configured to monitor a time-dependent course of the pressure difference (?p) and to determine a collapse of the longitudinal seal portion (18).
