Production of flexible walled bags, formed from a film of flexible material and having two flexible strips (2a, 2b) bordering the bag opening, involves fixing the strips in a parallel manner with each strip near an edge of the sheet, guiding the strips together while closing the bag and connecting the strips via their ends. An independent claim is included for a corresponding installation, with devices for fixing each strip (2a, 2b) near an edge of the film, two slides (11a, 11b) to guide the strips together while closing the bag and devices for connecting the strips. |
