The both side parts are overlapped with each other on the other side of the absorbent body. An overlapped part is bonded through a hot melt adhesive to form a connecting portion. A surface of the absorbent body on a side of the connecting portion is bonded to an internal surface of the wrapping sheet through hot melt adhesives, and the connecting portion of the wrapping sheet extends in a width direction to extend over both widthwise sides of a slit provided in the absorbent body.

  • Patent number: 10842690
    Abstract: An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is preferably attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The basis weight of the absorbent material in the central absorbent zone is higher than the basis weight of the absorbent material in each of the lateral absorbent zones for at least a first transversal section (S1). This relation is inverted along a second transversal section (S2) of the core.

    Abstract: A capacitive distance sensor includes a sensor element having an electrically conductive, elongated, flat sensor area which in turn contains a number of holes. The sensor area is completely surrounded by an electrically non-conductive insulating body, with the result that the insulating body completely covers the edge regions of the holes. The sensor element is produced, in particular, by first of all making the holes in the sensor area. In a subsequent step, the sensor area is completely encased by the insulating body which also completely fills the holes in the sensor area.
