A method, with its producing device, for welding the front edges of superimposed layers of thermoplastic material, in particular for closing the open ends of flexible tube sections of synthetic material used for the manufacture of sacks or bags, characterized in that the heat of welding is made to act on the front edges in the direction of the plane of the layers of material, and that is why the front edges melt forming a weld bead by fusion.
