<p>A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base support structure which includes coated elements having a coating of a first polymeric resin material. The base support structure itself may be woven or braided from yarns among which are included coated yarns. The base support structure may also be a spirally wound fabric strip having a number of non-overlapping, abutting turns joined along a continuous seam. Further, the base support structure may be a laminated structure having more than one layer, each of the layers being either a woven, braided or spirally wound structure and each including coated yarns having a coating of a first polymeric resin material. The base support structure is in the form of an endless loop, at least one of the inner and outer surfaces of which is coated with a second polymeric resin material. The second polymeric resin materials impregnates the structure of the base support structure, rendering it impermeable to oil and water. The first and second polymeric resin materials have an affinity for one another, so that the coating of second polymeric resin material on the base support structure as a whole establishes a chemical, as well as a mechanical, interlock with the coated yarns having the coating of first polymeric resin material. <IMAGE></p> |
