Abstract: The invention specifies an in particular horizontal tubular-bag machine (5) in which objects (2) which are provided for packaging are conveyed along a conveying direction (6) by means of a conveying apparatus (51). The tubular-bag machine (5) has an apparatus (50, 43) for producing from a packaging sheet material (12) a packaging tube (13) extending in the conveying direction (6), and also has a longitudinal-connection device (53, 54) and a transverse-connection device (44) for producing longitudinal and transverse connections in the packaging tube (13). Also provided is a gas-adjusting device (8) with an introduction head (80) for engaging in the packaging tube (13) in a direction transverse to the conveying direction, wherein the introduction head (80) has a first gas-passage opening (802, 804, 805, 807, 808) and at least one second gas-passage opening (802, 804, 805, 807, 808) by way of which a gas is fed into the packaging tube (13) or removed therefrom.
