Abstract
A tufting machine and a method of controlling the tufting machine to form a tufted article having varying pattern effects, such as forming cut and loop pile tufts of yarn in a graphics type pattern, defining a yarn feed effect pattern and a shifting needle bar effect pattern, and combining the two patterns. The yarn feed of the tufting machine is controlled to compensate for pattern shifts while a hook assembly having a series of hooks/loopers and a series of clips independently moveable between extended and retraced positions is selectively controlled to cause a transition from cut pile tufts to loop pile tufts and loop pile tufts to cut pile tufts according to the programmed pattern information.
