    Patents

    Apparatuses and Methods for Making Absorbent Articles:

    U.S. Patent No. 9,763,836

    11.10.17
    Paul Anthony Kawka, Kelso Township, IN; Uwe Schneider, Cincinnati, OH; and Gary Dean LaVon, Liberty Township, OH.
    Assigned to The Procter & Gamble Company, Cincinnati, OH.

    Filed: 3/2/15
    Issued: 9/19/17

    A method for assembling disposable pant diapers, each pant diaper comprising a chassis having a first end region and an opposing second end region separated from each other by a central region, and having a longitudinal axis and a lateral axis, the chassis comprising: a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the method comprising the steps of: advancing a first continuous substrate in a first machine direction at a first speed, the first continuous substrate defining a width in a first cross direction, wherein the first continuous substrate includes first registration features arranged along the first machine direction; advancing a second continuous substrate in a second machine direction at a second speed, the second continuous substrate defining a width in a second cross direction, wherein the second continuous substrate includes second registration features arranged along the second machine direction; cutting the second continuous substrate into discrete chassis, wherein each chassis advances such that the longitudinal axis is parallel with the second machine direction; turning each chassis such that the lateral axis is parallel with the first machine direction; bonding the first end regions of each chassis with the first continuous substrate; detecting positions of first and second registration features relative to each other along the first machine direction and along the first cross direction; changing placement of first and second registration features relative to each other along the first machine direction for each chassis subsequently bonded to the first continuous substrate based on detections of first and second registration features relative to each other on chassis previously bonded to the first continuous substrate by at least one of: adjusting the first speed of the first continuous substrate and shifting the second continuous substrate in the second cross direction; and changing the placement of first and second registration features relative to each other along the first cross direction for each chassis subsequently bonded to the first continuous substrate based on detections of first and second registration features relative to each other on chassis previously bonded to the first continuous substrate by at least one of: shifting the first continuous substrate in the first cross direction and adjusting the second speed of the second continuous substrate in the second machine direction.
