  • Patent number: 8015999
    Abstract: A weaving machine for weaving a three-dimensional distance woven fabric including two outer fabrics and inter-yarns connected with the outer fabrics is provided. The weaving machine includes a warp let-off mechanism, heald frames, a picking mechanism, a beating-up mechanism, a yarn raising mechanism, and a take-up mechanism. The warp let-off mechanism includes at least two warp beams for providing and transferring warps. A plurality of vertically arranged heald wires are supported by each of the heald frames, wherein each of the heald wires has a heald eye for the warps passing through. The warps are driven and divided into two warp layers by the heald frames such that a shed is formed between the two warp layers. The picking mechanism transfers wefts to pass through the shed. The yarn raising mechanism is suitable for passing through the shed and raising parts of the warps functioning as the inter-yarns.
