US Patent 3,719,210 (granted March 6, 1973; Emerson et al., assigned to Monsanto) describes a circular weaving machine and the process for making thick-walled, integrally woven, three-dimensionally shaped fabrics on a mandrel. Several Jacquard heads form warp sheds around a vertical axis while filling yarn inserters travel around the mandrel and the mandrel is raised at the rate of weaving. The fabric can be a cylinder, a cone, or an irregular shape such as an airplane wing or boat hull. The patent has 27 sheets of drawings (77 figures) covering mechanical assemblies, mandrel shapes, hydraulic and electrical control circuits, and diagrams of warp and filling yarn arrangements, followed by the specification and 69 claims.
