Abstract
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.
Claims6
A machine for tying knots onto a linear base material, said machine having initialization end and a completion end, the improvement comprising:
- a cutter system, said cutter system being proximate the center of said machine and having a knife and a looper, said looper moving to a receiving position to receive threads of yarn from a needle and to a rest position to await a subsequent thread of yarn, and said knife moving to cut said yarn positioned on said looper;
- a yarn needle, said yarn needle being on a first side of said machine and moving from said first side to said center of said machine, said yarn needle carrying yarn to said looper;
- a roller assembly, said roller assembly having a bristle roller and a grooved worm, said bristle roller being in contact with said grooved worm, said grooved worm receiving yarn from said yarn needle and moving said yarn toward said completion end;
- a picker assembly, said picker assembly extending from said completion end of said machine and pulling a predetermined number of yarn strands together;
- a knot tying needle assembly said knot tying needle assembly being affixed at one end of a first side of said machine and having a movable needle with an open eye, said movable needle being extendable to a knot tying area proximate said roller assembly, a knot tightener, said knot tightener being positioned to interact with said movable needle and a rotating gear, said rotating gear rotating said movable needle in clockwise and counterclockwise directions;
- a filler hook assembly, said filler hook assembly being movably affixed to said second side of said machine and moving to grab and lift said cut yarn from said roller assembly;
- a needle rod, said needle rod contacting said movable needle and prevent said yarn from moving along said moveable needle while said knot is being tied;
- a rake assembly, said rake assembly having a rake, said rake rotating around a wheel and being positioned come in contact with said tied knots and move said tied knots toward said completion end;
- wherein said cutter assembly, said yarn needle, said roller assembly, said picker assembly, said knot tying needle assembly, said filler hook assembly, said needle rod and said rake assembly are synchronized with one another to tie fringe knots.
