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.
