发明名称 Device for correcting the position of the cut in the manufacture of infusion bags
摘要 The device corrects the position of the cut in the manufacture of infusion bags from a heat-weldable synthetic film sheath (1) on which transverse welds (8) are made and in which perforations (9) are produced in the middle of the welds (8), for suspension of the infusion bags, the sheath (1) being then pulled in order to be cut transversely into sections, each corresponding to one bag. At the cutting station, means (19) are provided for detecting each perforation (9) of the sheath (1) and for moving it locally in its backwards direction. The perforation (9) and the corresponding weld (8) are thus brought into a predetermined position linked with that (L) of the cutting means. <IMAGE>
