A stitch distribution control system for a tufting machine for controlling placement of yarns being fed to the needles of the tufting machine by yarn feed mechanisms to form a desired pattern. A backing material is fed through the tufting machine at an increased stitch rate as the needles are shifted according to calculated pattern steps. A series of loopers or hooks engage and pick loops of yarns from the needles. The yarn feed mechanisms further can be controlled so that selected loops of yarns can be back-robbed so as to be hidden from view in the finished patterned tufted article.

一种用于簇绒机的针迹分配控制系统用来控制由纱线馈送机构馈送给簇绒机的针的纱线的放置以形成预期图案。当针根据计算的图案步进移位时，按照增大的织距馈送衬底材料以使其经过簇绒机。一系列套口机或钩接合针并从针拾取纱线的毛圈。还能够控制纱线馈送机构从而使得选择的纱线的毛圈能够被去除以便被隐藏在完工图案簇绒制品中。
