Abstract
The invention discloses a middle triangular part of a computerized flat knitting machine, which comprises a third track and a fourth track, wherein the third track and the fourth track are used for hanging meshes and connecting stitches, form a splayed shape and are two one-way needle penetrating tracks. A fourth left chute, a middle groove, a third right chute and a third right chute form a one-way needle penetrating track c, and symmetrical portions form a one-way needle penetrating track d. A step is arranged at the lower portion in the fourth left chute to enable a space of the upper portion in the fourth left chute to be used for needle butts of combined needles to slip out right, and the height of the step is smaller than the depth of the fourth left chute. The step and the wide inlet position of the fourth left chute form slope transition. By means of the tracks of the middle triangular part, needle bumping or stitch missing phenomenon is avoided effectively. When stitch-connecting weaving is performed, the slipping-off of the needle butts is limited so as to facilitate slipping-out, slipping-into of the needle butts is facilitated, and accordingly running of the computerized flat knitting machine is stable.
