A vertical bag-making/filling machine (1) comprises: a film-feeding unit (8) which intermittently feeds a film (F) formed into a tubular shape downward; a nozzle (10) supplying contents (X) into the film; a sealing-off unit (17) arranged below a lower end of the nozzle and forming a bag body (Fg) by heat-sealing the film in a transverse direction; a lower shaping unit (30) regulating swelling of the film on the lower side of the sealing-off unit; an upper shaping unit (40) regulating the swelling of the film on the upper side of the sealing-off unit; and a separating unit (25) for separating the bag body (G) fully filled with the contents by cutting the transverse seal (Y1, Y2) formed by the sealing-off unit.

There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises an isolation chamber (10) separating an inner environment (11) containing a sterile gas from an outer environment (12). The packaging apparatus further comprises a delimiting element (48) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (49) and a second space (50). The packaging apparatus (1) also comprises a pressurizing device (47) for pressurizing the second space (50) by means of a pressurized sterile gas. The delimiting element (48) is arranged within the isolation chamber (10).

In a method for forming a lateral sealed portion, a liquid packing material can be filled without biting bubbles, granulates and so on included in the liquid packing material into the lateral sealed portion. In a method for forming a lateral sealed portion with a pair of lateral sealing rolls after a packaging film fed and run is folded at its central portion and a vertical sealing is performed at their side edge parts to shape into a cylindrical form and a liquid packing material is filled into an inside of the cylindrically formed packaging film, at least a folded side part of the cylindrically formed packaging film is pushed with a pushing means arranged between heat sealing bars located at equal intervals in a circumferential direction of the lateral sealing roll and the lateral sealed portion is formed at a pushed position with the pair of lateral sealing bars.

The invention relates to a tubular bag machine and to a method for operating a tubular bag machine (01) for the continuous production of tubular bags (20), which are filled with a mixture of liquid and solid filling components (29, 30). A formatting device (18), by means of which the bag shape of the tubular bag (20) open at the top seal is formatted, is disposed below the wiper device (16), the formatting device (18) comprising at least two formatting elements (19), which are contacted on the outer side of the film tube (34) and are displaced between an open position and a formatting position. The horizontal distance between the formatting elements (19) is larger in the open position than in the formatting position. The formatting elements (19) are moved to the open position before and/or while filling the tubular bag (20) with filling material (29, 30). The formatting elements (19) are moved to the formatting position while and/or after filling the tubular bag (20) with filling material (29, 30) and before producing the top seam to remove air from the air bubble (32) in the top area of the tubular bag (20) via filling material components (29, 30).
