▎ 摘  要

NOVELTY - The Manufacturing method involves providing (100) a backsheet layer, a cover strip layer, and an absorbent core layer. An opening is cut (101) into the backsheet. The cover strip is placed (102) between the layers. The cutting is speed-synchronized with respect to the provision of the layer in such a manner that the opening is placed at the same position for every article in a sequence of articles. The ink has the graphene, graphite, nano-carbon-tubes, polyacetylene, polypyrrole, polyaniline, poly(pyrrole) (PPY), polyanilines (PANI), poly(thiophene) (PT), poly(p-phenylene sulfide) (PPS), poly(p-phenylene) (PPP), Poly(acetylene)s (PAC), Poly(p-phenylene vinylene) (PPV), poly(3,4-ethylenedioxythiophene) (PEDOT), and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. USE - Method for manufacturing an absorbent article (claimed). ADVANTAGE - The method ensures that undesired shift against a predefined target position especially in machine direction of a production line can efficiently and accurately be corrected. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the Manufacturing method. Providing a backsheet layer, a cover strip layer, and an absorbent core layer (100) Cutting an opening into the backsheet layer (101) Placing the cover strip layer between the backsheet layer and the absorbent core layer (102)
