ABSTRACT:
A tufting machine having multi-color selection capability for each tufting cycle which utilizes pneumatic pressure either positive or negative, or a combination of the two, to transfer the yarn or other tufting material to tufting elements, the yarn being severed before, during, or after threading, for subsequent placement into tufting relationship with a backing layer. The system comprises yarn guide passageways having abutting sections which are relatively movable to create an opening through which a yarn-severing means severs the yarn into selectively-sized bits. The relative positions of the yarn-severing means and the abutting sections of the passageways are adjustable to provide yarn bits of selected varying lengths. Clamping means may be used to clamp the yarn at the tufting needles until tufting occurs. After tufting the tufted yarn is moved away from the needle position to avoid entanglement by the succeeding motions of the tufting.
