1. 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.
