A device (1) for producing bags from tubular bag bodies (10) comprises a transport device (2) which transports the bag bodies in a flat manner transversely to the longitudinal extent (L) thereof in a transporting direction (T) at a transport rate (V). While being transported, the bag bodies pass through processing stations (30, 40, 50, 60, 70, 80) by way of which at least one end region (13) of each bag body is formed into a cross bottom and optionally a cover sheet (19) is applied to the cross bottom. A transfer device (4) moves the bag bodies (10) to be transported by the transport device at a transfer rate (U), with respect to bag bodies conveyed at a transport rate (V), by a feeding distance ([Delta]y) in the transporting direction (T) and then transfers them to the transport device (2). The feeding distance ([Delta]y) is selected such that successive bag bodies overlap one another, wherein the overlapping width preferably corresponds to once or twice the height (h) of the triangular corner fold (14) whic
