ABSTRACT:
In a device for filling bags made from foil or similar material, the edges of each bag which form an opening are fed in so that each edge is held between a semi-rigid plate and a conveyor belt which is held against the plate to frictionally grip the respective edge of the bag. There are two semi-rigid plates which are hinged together at their ends, and to open the bag, one hinged end moves towards the other to cause the plates to bow out together with the surrounding conveyor belts. The bag can be filled through the opening between the plates.
