Abstract: The shedding movement and the characteristics of the shedding mechanism of traditional loom are analyzed in this paper. According to the special requirements to shedding mechanism for weaving three-dimensional fabric, a new electronic shedding system is developed to form the clear multi-shed with multi-layer warp which is controlled by PLC and driven by servo motor. This method has simplified the shedding mechanism and improved the flexibility and reliability of the shedding mechanism. It is introduced that the general design of three-dimensional loom’s shedding system, including the driving system’s hardware configure and its software’s controlling principle. The new shedding system developed has been applied in a three-dimensional loom prototype successfully.
