Abstract: First this paper introduced the fine-gauge Textronic lace machine. Then, by discussing the working principles of the fall-plate, weft insertion knitting and trimming and based production practice, it introduced in detail the key points in manufacturing process such as the process design of trimming end, trimming length control and the arrangement of guide bars. Finally, it analyzed the selection of lace materials and the pickup and trimming operations. The results in this paper are helpful to improving the research and production of this kind of lace fabric.
