ABSTRACT:
Objects are packeted in bags (5) by means of a chain (1) of flat, flexible bags being conveyed, open at the top, through a filling station (12). Each bag in the chain has a rear main wall with a lip protruding from the opening, out past the edge of the front wall (51). In the station the lip is allowed to run along a support line which, seen in the general direction of feed of the chain of bags, diverges therefrom both horizontally and vertically so that the opening of the bag (5) can easily be opened by a jet of air without creasing the chain of bags.
