1. A method for manufacturing a disposable fluid-handling article, the disposable fluid-handling article comprising at least two primary components made continuously from bulk starting materials, the method comprising the steps of:

  • a) feeding a first polymeric bulk starting material into at least one first polymeric extrusion apparatus disposed adjacent to a first collecting surface moving at a first velocity in relation to the first polymeric extrusion apparatus;

    b) extruding a first molten stream of a first polymeric material from the first polymeric extrusion apparatus;

    c) continuously forming a first primary component of the disposable fluid-handling article from the first molten stream;

    d) feeding a second polymeric bulk starting material into at least one second polymeric extrusion apparatus disposed adjacent to a second collecting surface moving at a second velocity in relation to the second polymeric extrusion apparatus;

    e) extruding a second molten stream of a second polymeric material from the second polymeric extrusion apparatus;

    f) continuously forming a second primary component of the disposable fluid-handling article from the second molten stream;

    g) joining the first and second primary components into a composite web, wherein the first primary component overlaps at least partially with the second primary component; and

    h) severing the composite web in a direction generally perpendicular to a machine direction so as to form the disposable fluid-handling article.
