摘要:
A system and method for tufting sculptured and multiple pile height patterned articles, including controlling placement of yarns fed to the needles of the tufting machine by a yarn feed mechanism to form varying patterns includes a backing support over which the backing is fed, and which lifts/and biases the backing to a raised position. As the backing material is fed through the tufting machine, a series of loopers or hooks engage and pick loops of yarns from the needles. The yarn feed mechanism will be controlled to create a tension in selected loops of yarns, to cause the backing material to be pulled against the bias or spring force applied by the backing support toward the needle plate of the tufting machine to create tufts of different pile heights.
