Abstract: 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).

Abstract: In order to allow stacks (137) of groups of items (123) placed one on top of the other, in particular comprising coffee pods, to be packed in tubular bags (16) by means of a vertical tubular bag machine (1), it is proposed either to adapt a filling pipe (6) to the horizontal dimensions of the groups of items (23) or to provide it with an insert (125) in order to stabilize the stack during its falling movement in the filling pipe (6). The insert (125) is similarly adapted to the geometry of the items in order to stabilize them during their fall in the filling pipe (6).

A separate longitudinal welding device for welding of an area adjacent to the edge of the tube is provided. It is thus possible to produce directly side-by-side a longitudinal seam and a welded edge. A bag-opening aid or a reclosing aid can be integrated into the longitudinal seam or the edge.
