Methods are known for conveying bags in the form of a continuous web such that they open at a suitable place during continuous conveyance and during maintenance of the open condition so they can be filled and sealed after closing. Prior art methods utilise complicated methods for retention. According to the invention, the bag web is suspended on horizontal studs mounted on carrier chains running in such a way that the bags open and a surrounding groove around the studs along the chains prevents the bags from falling off during passage of filling stations etc.
