  • Patent number: 5494622
    Abstract: The present invention provides an apparatus and method for forming a composite web having selected discrete pocket regions which are distributed on a carrier layer and contain high-absorbency material. The invention includes a pattern chamber having opposed side walls, an entrance end wall and an exit end wall. A particulate supplying mechanism provides particles of high-absorbency material into the pattern chamber, and a web supplying mechanism provides a gas permeable carrier layer. A foraminous forming mechanism moves the carrier layer through the pattern chamber, and the forming mechanism includes a pattern of openings which are formed therethrough and are arranged to provide for a selected pattern of the discrete pocket regions. A vacuum supplying mechanism provides a selected level of relatively low gas pressure at an underside region of the forming mechanism to produce a selected gas-flow through the carrier layer and the foraminous forming mechanism to form the pocket regions.
