Abstract： To address the issues of high labor intensity and low forming eficiency caused by manual weft insertion in narrow channels during the forming processes of soft-hard blended preforms，an automated weft insertion system was developed based on an S-shaped trajectory of continuous carbon fiber tow.The formation mechanism of the S-shaped trajectory was analyzed to establish the synergistic relationship between carbon fiber bundle positioning and coordinated multi-mechanism motions.A system architecture was designed，with the weft delivery mechanisms， electronic weft insertion mechanisms and post-insertion control mechanisms as the core components. Prototype experiments demonstrate that the system achieves continuous and stable weft insertion in narrow channels at a rate of 12.5 picks per minute.
