Abstract
A machine and a method for manufacturing a sanitary product with an hourglass shaped absorbent core, such as a panty liner or a light-inco diaper. The machine and the method allow virtually scrap-free shaping of the core into an hourglass shape.
Claims6
A method for manufacturing sanitary products, comprising:
- providing a first core material comprising a first web material,
- providing a second core material comprising a second web material,
- providing a carrier material comprising a third web material,
- feeding each of the first core material, the second core material and the carrier material in a machine direction,
- cutting the first core material into a first pattern comprising first pairs of oppositely tapering figures, each first pair of oppositely tapering figures comprising a first tapering figure and a second tapering figure adjacent and aligned in the machine direction,
- spacing the first tapering figure from the second tapering figure in the machine direction,
- spacing the first tapering figure from the second tapering figure in a cross direction transverse to the machine direction,
- laying the first tapering figure and the second tapering figure spaced in the machine direction and in the cross direction onto the carrier material,
- cutting the second core material into a second pattern comprising second pairs of oppositely tapering figures, each second pair of oppositely tapering figures comprising a third tapering figure and a fourth tapering figure adjacent and aligned in the machine direction, the third tapering figure and the fourth tapering figure having a reverse tapering with respect to the first tapering figure and the second tapering figure, respectively,
- spacing the third tapering figure from the fourth tapering figure in the machine direction,
- spacing the third tapering figure from the fourth tapering figure in the cross direction,
- laying the third tapering figure and the fourth tapering figure spaced in the machine direction and in the cross direction onto the carrier material to overlap a portion of the third tapering figure with a portion of the first tapering figure into a first hourglass shape, and a portion of the fourth tapering figure with a portion of the second tapering figure into a second hourglass shape.
