ABSTRACT:
A papermaking through-air drying belt and a method of making the same, as well as a paper web produced on the belt and the process of making the web are disclosed. The belt comprises a resinous framework having a web-side surface defining an X-Y plane, a backside surface opposite the web-side surface, a Z-direction perpendicular to the X-Y plane, and a plurality of discrete deflection conduits extending between the web-side surface and the backside surface. Each of the discrete conduits has an axis and walls. The axes of at least some of the discrete conduits and the Z-direction form acute angles therebetween. Preferably, the belt also comprises an air-permeable reinforcing structure joined to the resinous framework. The paper web produced on the belt has at least two regions disposed in a non-random and repeating pattern: macroscopically monoplanar, patterned, and essentially continuous network region, and a domes region comprising discrete domes extending from the network region in at least one direction such that this at least one direction and the Z-direction form an acute angle therebetween.
