<p>A bag manufacturing plant has three processing areas (4-6). Both foils (1, 2) lie on each other in the first processing area (4), are separately guided in the second processing area (5) and lie on each other again in the third processing area (6). In the second processing area (5), a tapping device, for example a small tube, is placed on the foils, and in the third processing area (6) the tapping device is welded to the foils. In the first processing area, the foils may be for example preformed or pre-cut. By dividing the path followed by the foils into three processing areas, it becomes possible to pre-process simultaneously both superimposed foils before the tapping device is added, while much space remains nevertheless available for placing the tapping device.</p> |
