Abstract

A papermaking belt and paper made thereon. The papermaking belt comprises a patterned framework and a reinforcing element. The papermaking belt may be used as a through air drying belt, a forming wire, a backing wire, a conventional press felt, etc., The papermaking belt has a reinforcing element and a framework extending from the reinforcing element. Intermediate various portions of the framework are deflection conduits. The framework is interrupted and subdivided by synclines. The framework, synclines and deflection conduits respectively impart first, second and third values of intensive properties to regions of the paper made on these portions of the belt. The value of the intensive property of the regions of the paper corresponding to the synclines is intermediate the value of the regions of the paper corresponding to the framework and deflection conduits. For example, if the papermaking belt according to the present invention is used as a through air drying belt, the density of the regions of the paper corresponding to the synclines will be less than the density of the regions of the paper corresponding to the framework but greater than the density of the regions corresponding to the deflection conduits. Conversely, if the papermaking belt according to the present invention is used as a forming wire, the basis weight of the regions of the paper corresponding to the synclines will be greater than the basis weight of the regions corresponding to the framework but less than the basis weight of the regions corresponding to the deflection conduits.
