The invention discloses a pattern-stacking-knitting needle control method of a computerized flat knitting machine. The pattern-stacking-knitting needle control method includes the steps that 1, selected needles, spring needles and long needles of the computerized flat knitting machine synchronously enter needle traveling troughs; 2, machine heads swing left and right, bearded needles are in the knitting state; needle selecting devices do not work; 3, the selected needles enter a needle receiving, tucking and traveling trough through first needle pushing triangles; 4, a spring-needle traveling trough changes along with a selected-needle receiving, tucking and traveling trough; a stepping motor rotates, a left needle receiving pressing sheet and a right needle receiving pressing sheet slide downwards, a tucking pressing sheet slides upwards, and a spring-needle tucking and traveling trough is formed; the spring needles enter the spring-needle tucking and traveling trough from the lower ends of needle backing triangles, and a long-needle traveling trough changes along with the spring-needle tucking and traveling trough through the left needle receiving pressing sheet, the tucking pressing sheet and the right needle receiving pressing sheet accordingly; the spring needles push the long needles, the long needles enter the portion between a disc mountain and mesh guide blocks from the upper ends of the needle backing triangles accordingly, penetrate through two waists of the disc mountain and slide out in parallel, and a long-needle tucking and traveling trough is formed; the long needles slide in the needle tucking and traveling trough to push the bearded needles to achieve pattern-stacking-shaped knitting of the bearded needles.
