The technical sector of the invention is that of the domain of bag-forming by packaging such as bags and especially sachets, made from flat webs folded and sealed to form bags which are then filled with liquid, pasty or pulverulent product, and closed. A bag-forming line according to the process of the present invention comprises a device for opening a sachet of rectangular shape made by two walls of supple material fast on three sides and constituting at least one bag, such that it comprises at least two suction cups disposed opposite so that they may be placed against each wall of said sachet and adapted to draw thereon, in order to open the walls at the level of the fourth side not fast with said bag; it comprises at least two pairs of said suction cups mounted at the end of arms mobile with respect to fixed guides and forming, between those disposed on the same side and dis-placeable simultaneously, a divergent angle whose aperture is oriented opposite that of the same aperture formed by the arms disposed on the other side.
