ABSTRACT:
A woven papermaking belt having a paper contacting top surface plane and an opposed backside. The belt comprises a fabric having yarns disposed, in part, in the top surface plane to form knuckles. The belt further comprises reinforcing piles extending from a proximal end to a distal end. The distal ends of the reinforcing piles are disposed between the top surface plane of the papermaking belt and the backside of the papermaking belt. The reinforcing piles resist applied loads and may prevent deflection of the knuckles during the papermaking process. The applied loads may either be normal to the belt, as occurs during imprinting, within the plane of the belt, which causes sleaziness of the belt, or both. The belt according to the present invention may have piles with proximal ends disposed at two or more different elevations, as well as distal ends, which are disposed at two or more elevations. This arrangement provides a belt which imprint different densities onto paper during papermaking, according to the ability of the piles to resist compressive loads applied normal to the plane of the belt. In one alternative embodiment, the piles may be disposed between the first and second layers of a multi-layer papermaking belt. The belt according to the present invention is particularly suitable for woven papermaking fabrics having long, unsupported knuckles.
