Abstract
Abstract A thick-walled, integrally woven, three-dimensionally shaped fabric which is produced on a circular type weaving machine is comprised of a plurality of yarn systems each of which defines a plurality of yarn planes with the yarn planes of each yarn system being distinct and traversing selected yarn planes of the other yarn systems. The fabric is woven upon the surface of a mandrel with the resulting shape being determined by the action of Jacquard means on the yarn systems and by the three-dimensional shape of the mandrel. The resulting fabric may be woven in the shape of a cylinder, a truncated cone, or as irregular shapes, such as, an airplane wing, a boat hull or the like.
