Single carriage double system. This series is the computer flat knitting machine with take down comb. Advanced scissors, clips and take down comb are added on the basis of the double system series. The machine includes two scissors and four clips which are controlled by the six motors separately. The program instruction can be executed simultaneously or separately to increase the production efficiency and reduce the waste of yarn. The take down comb adopts closed U type compound needle to hold and knocks over the yarn reliably.
