A machine for tying knots in a linear substrate that is woven simultaneously on the machine or prewoven and fed through the machine. A cutter system uses a knife and a looper independently operated by a series of clamp blocks and connecting links. A yarn needle carries the yarn to the looper for cross weaving. A roller assembly maintains the cut yarn in a taut position. An adjustable picker assembly having cams gathers a number of yarn strands together. A knot tying needle assembly has one end affixed to the machine with an open eyed movable needle for grasping the gathered strands. An adjustable knot tightener interacts with the movable needle to tighten the knot with the aid of an oscillating gear. A rake assembly moves the tied knots to the completion end of the machine.
