A method for making bags of synthetic material in which a tubular foil web of synthetic material is advanced in steps corresponding to the length of one bag. A continuously heated pair (11) of welding jaws grips the tubular foil web (3) of synthetic material prior to cutting and fixes the web in position. The tubular foil web (3) is then cut by means of the transverse cutting knife (10) before the heat of the pair (11) of welding jaws is completely transferred to the tubular foil web (3) of synthetic material. Then the heat is completely transferred to weld the bottom seam of the bag.
