Abstract
A method of making a belt-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface moving at a transfer surface speed. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the transfer surface speed, and the web is creped from the transfer surface and redistributed on the creping belt to form a web. The web includes hollow domed regions, connecting regions, and transition areas. The web is dried to produce the belt-creped absorbent cellulosic sheet.
