ABSTRACT:
Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with different flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.
