A method includes distributing a powder onto a first sheet, periodically closing a distribution port by a first opening-closing portion, and periodically closing the distribution port by a second opening-closing portion in the same cycle period as that of the first opening-closing portion and at a timing later than that of the first opening-closing portion. The method also includes moving the second opening-closing portion such that it extends from an upstream-side edge of the first opening-closing portion toward an upstream side of a movement direction, during a time period during which the upstream-side edge of the first opening-closing portion overlaps the distribution port. Further, the method includes setting a difference between timings at which the first and second opening-closing portion overlap the distribution port, respectively.

PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
