Abstract: A shed-forming device and a method for using it are provided for creating a shed of warp yarns in a weaving machine. The shed-forming device includes a plurality of yarn separating elements operably disposed to one another within the weaving machine. The yarn separating elements individually separate the warp yarns into operational zones between the yarn separating element. A fluid supply apparatus supplies fluid to the yarn separating elements in the shed-forming device. The yarn separating elements direct the fluid to contact the warp yarns, forcing the warp yarns to form changeable sheds to allow proper weaving.

Abstract: A computer aided system suitable for use in the design of woven portions of fabric, which system has a computer programmed to display weaving patterns defined by different user-defined selections of each of a plurality of weaving pattern variables. Signals from the computer are received by a weaving apparatus which selects and controls the individual movement of weft yarns from a group of warp and weft yarns in the apparatus.
