Single head double system type, the roller device has a single roller and threading plate optional. Adopting the newest appearance design, the direct selecting needle triangle system controlled by the whole motor, together with the optimized system's functions of rapid reversing of the head, zero waiting of the shaking table, and continuous weaving without shear clamps, the head stroke and row number are effectively reduced, and the stability and efficiency of the machine are greatly improved. One row can support 256 variable regions, without disassembling rows, increasing the variety of pattern design, and realizing the weaving of different tissues and different densities in the same row; The function of fine-tuning on both sides can effectively solve the problem of different length of the cloth sheet and increase the flatness of the cloth sheet.
