Abstract A cut pile tufting machine which includes mechanism for feeding yarns at a higher or at a lower speed to selected needles under pattern control, oscillating tufting hooks each of which has spaced upper and lower bills which face in the direction opposite to the direction of travel of backing cloth through the machine, the upper bill only entering the loop just formed by a needle upon oscillation of the hook towards the needle, the upper bill being hook shaped and having a lower surface adjacent the tip of the hook along which the loops travel as the backing cloth travels through the machine towards a slot between the two bills, the loops being pulled through the slot, when under tension, to be caught in the bight of the hook to produce low pile and the loops, when not under tension, moving past the slot on to the lower bill to produce high pile, and knives which coact with the hooks to sever loops on both bills of the hooks.
