Title
(EN) Stitch distribution control system for tufting machines
Abstract
(EN)

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.
