ABSTRACT:
A press belt in the form of an endless loop includes crosswise and lengthwise reinforcing fibers. The crosswise reinforcing fibers are positioned adjacent to the outside surface of the belt and the lengthwise reinforcing fibers are positioned adjacent to the inside surface of the belt. The fibers are laid inside a casting cylinder and an elastomeric material is cast onto the fibers while the casting cylinder is rotating. The crosswise fibers are laid into the casting cylinder first so that they are adjacent to the outer surface of the belt and then the lengthwise fibers are laid over the crosswise fibers.
