Abstract
A tufting machine with a pair of closely spaced apart needle bars which reciprocate together but the needles carried by one bar may be controlled selectively to be either in a position to form pile or be retracted to a position where they do not form pile when the needle bars are driven toward the backing material selectively. A control system is provided to control the selection of the needles of the one needle bar and also the feeding of yarn to the needles of the one needle bar so that yarn from needles which are not tufting is drawn tight on the backing. The needles may be mounted in modules and selected needle modules may be independently controllable by pneumatic cylinders so that various overtufted patterns may be made by the controlled needles in a background formed by the needles in the other bar that tuft on every stitch.
