At the position where the pattern needs to be weaved, the first yarn mouth brings the ground yarn 11 into the needle hook of the second knitting needle and the second knitting needle sinks a distance without forming a loop, specifically, it can sink half of the needle position to form a hook and half-sunken state. The second yarn mouth carries the pattern yarn 23 and moves horizontally. At the position where the floating line segment 22 needs to be weaved, the pattern yarn 23 bypasses the corresponding first knitting needle to form a floating line. At the position where the pattern needs to be weaved, the second yarn mouth brings the pattern yarn 23 into the second knitting needle, and the second knitting needle carries the pattern yarn 23 and the ground yarn 11 to weave in a loop at the same time. The ground yarn 11 is first brought into the first knitting needle and enters a half-sunken state. The pattern yarn 23 enters the first knitting needle later. The ground yarn 11 and the pattern yarn 23 are woven at the first knitting needle at the same time to form an upper and lower coil.
