Still taking the lower needle 20 as an example, when knitting is started, no yarn 27 is in the crochet hooks of all the lower needles 20 and idle rotation is carried out without participating in knitting, the servo motor can drive the lower needle cylinder 12 to rotate forward through forward rotation, at this time, the upper needle selector 28 can control the lower needles 20 to carry out needle withdrawing according to jacquard motions, the lower needles 20 controlled to carry out needle withdrawing move up and down along the needle withdrawing part 142 of the lower jacquard triangle 14 and the needle moving track of the needle pressing triangle 41 to hook the yarn 27 for knitting, while the lower needles 20 not subjected to needle withdrawing continue idle rotation and do not participate in knitting, so as to form a first path of yarn, when the last lower needle 20 involved in knitting passes through the lower needle selector 28, the servo motor can change the direction to drive the lower needle cylinder 12 to rotate reversely, if the next needle selector 28 does not increase the needle withdrawing number of the lower needles 20 at this time, the lower needles 20 previously involved in knitting return according to the same height of original path, so as to knit a second path of yarn with the same width as the first, the cloth formed by the back and forth knitting is stripe cloth, and the width of the stripe cloth is determined by the number of the lower needles 20 participating in the knitting; after the first path of yarn is formed, the next path of needle selector 28 increases the needle output number of the lower needle 20 and participates in knitting, the needle output action of the second path of increased lower needle 20 is the same as that of the first path of increased lower needle 20, the needle output number of the lower needle 20 is gradually increased in such a way of reciprocating, the cloth formed by combining the final looping knitting is a strip can cloth, and in the process, the needle selector 28 is equivalent to a lower needle 20 needle output number control system, so that the limitation that the traditional jacquard mechanism 2 can only be used as jacquard is distinguished, the lower needle 20 automatically falls back along with the forward and reverse rotation of the lower needle cylinder 12 after needle output, the vamp machine has the needle receiving and releasing functions, the width of the cloth knitted by the lower needle 20 can be controlled only by inputting a program similar to knitting into a knitting system, the strip cloth, the tube cloth knitting or the mixed knitting of the strip can be realized, and the defect that the traditional circular knitting machine can only knit the tube cloth is solved, taking the vest knitted in fig. 13 as an example, the vest comprises four shoulder straps 51 and a garment body 50, assuming that 50 lower needles 20 are required for knitting one shoulder strap 51 and 500 lower needles 20 are required for knitting the garment body 50, during the knitting process, the lower needle cylinder 12 rotates forward and backward along with a servo motor, the four needle selectors 28 are firstly used for controlling 50 lower needles 20 of the corresponding lower needle cylinder 12 to go out, and the rest lower needles 20 do not go out, so that the four shoulder straps 51 are knitted first, because the width of the connecting part of the shoulder straps 51 and the garment body 50 is gradually increased, the required lower needles 20 for knitting are increased, at this time, the knitting of the vest can be completed only by using the two adjacent needle selectors 28 to control the number of the outgoing needles 20 to gradually increase, and after the knitting is completed, the yarn 27 is cut by the automatic yarn cutting mechanism 15, the lower needles 20 continue to be knitted into the vest to complete the needle insertion, and automatically drop from the center of the lower needle cylinder 12, at this time, the crochet needles of all the lower needles 20 have no yarn 27 and are positioned at the height which does not participate in knitting initially, so that preparation is made for knitting the next vest, and the knitted vest only needs to sew four shoulder straps 51 in pairs; the vest woven by the method saves the step of cutting cloth after the traditional vest is woven, effectively improves the production efficiency of the strip tube cloth similar to the vest, and the upper needles 18 and the lower needles 20 can be simultaneously woven according to the principle, so that the strip tube cloth and the strip tube cloth have the characteristics of double-faced fabric.

In addition, after the jacquard sheet 29 drives the lower needle 20 to go out of the needle, the falling height of the lower needle 20 is controlled by the needle pressing triangle 41, meanwhile, the yarn feeding height of the lower needle 20 during falling back determines the diameter of the big end and the small end of the fabric, and the needle pressing triangle 41 is driven by the stepping motor 44 to move up and down, so that the falling height of the lower needle 20 can be artificially controlled, the two ends of the fabric are reduced, and the weaving of the tubular fabric or the stocking shoes with gradually changed diameters is smoothly completed.
