Abstract: A downwardly acting air-outlet nozzle (8) is provided in a device (1) for packaging between a funnel (2) and a fill pipe (5) for the purpose of producing an air stream and to thus enable filler to fall quicker through the fill pipe (5). In order to be able to determine and regulate the pressure (P) in the lower area of the foil tube, the pressure P is determined by means of a measuring device (26) and a measured-value indicator (27). The measuring device (26) can include a hollow pipe (29), which guides the pressure (P) to a measuring device (28). Tubular bags with a specific interior pressure can be manufactured with the device (1).
