Zusammenfassung:	An absorbent sheet made by a process that includes the steps of forming a nascent web from an aqueous papermaking furnish, and creping the nascent web on a multilayer belt that includes (i) a first layer made from a polymeric material having a plurality of overlapping openings, and (ii) a second layer attached to the first layer, with the nascent web being deposited onto a surface of the first layer. The absorbent sheet includes a plurality of hollow domed regions projecting from a side of the absorbent sheet. Una hoja absorbente elaborada mediante un proceso que incluye los pasos de formar una red naciente a partir de una fibra acuosa de elaboración de papel y crepar la red naciente en una correa multicapas que incluye (I) una primera capa elaborada de un material polimérico con una pluralidad de aberturas superpuestas y (II) una segunda capa unida a la primera capa y la red naciente depositada en una superficie de la primera capa. La hoja absorbente incluye una pluralidad de regiones en domo huecas que se proyectan desde un lado de la hoja absorbente.
