Abstract: A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

Abstract: 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.
