Abstract (en)

[origin: WO9853138A1] A papermaking through-air drying belt (10) 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 (10) comprises a resinous framework (20) having a web side surface (21) defining an X-Y plane, a backside surface (22) opposite the web-side surface, a Z-direction perpendicular to the X-Y plane, and a plurality of discrete deflection conduits (30) extending between the web-side surface and the backside surface. Each of the discrete conduits (30) has an axis (33) and walls (35). The axes (33) of at least some of the discrete conduits (30) and the Z-direction from acute angles (Q) therebetween. Preferably, the belt also comprises an air-permeable reinforcing structure (50) joined to the resinous framework (20). 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 from an acute angle therebetween.
