    摘要： Several embodiments of an improved absorbent insert or core are disclosed. According to one embodiment, the insert comprises a fluff layer physically integrated to at least one layer of laminate consisting of at least one tissue layer and polymer powder secured to it and supported on it. The fluff layer and the laminate are embossed between rollers that physically integrate the two layers and produce transfer sites through which liquid is rapidly transferred into the fluff layer, away from a wearer. In another embodiment, an absorbent insert is produced by embossing a laminate between a smooth roller and a patterned roller and trimming and folding the embossed laminate to produce an insert with a central region with an exposed pattern of embossed depressions and, on each side of the central region, lateral regions with an exposed, smooth surface. According to another embodiment, an absorbent insert is produced by depositing super absorbent polymer powder on a portion of a layer of fluff, covering the powder with at least one tissue layer, and embossing the assembly to produce an integrated absorbent insert. According to another embodiment, an absorbent insert is produced by depositing super absorbent polymer powder on a portion of a layer of fluff, covering at least a portion of the fluff with polymer deposited thereon with at least one laminate layer, and embossing the assembly to produce an integrated absorbent insert.

    摘要： A method and apparatus for producing fibrous web pieces by die cutting the pieces from a continuous web. In the method, a fibrous web is provided having adjacent corrugations usually filled with a powder, and the powder-filled web is passed through a matched cutting die set intermittently which cuts and punches out the individual web pieces. Following the web cut out step, the web pieces are transferred downwardly onto a shuttle conveyor, and the pieces moved forward and simultaneously spread apart to permit subsequent convenient placement of the pieces. The cutting die apparatus includes matched punch and body die units which closely interfit with less than about 0.001 inch total clearance, so as to cut and punch out the fibrous web pieces from the continuous web.
