Abstract
The yarn folding mechanism includes a pair of wires extended across a plurality of strands of yarn between two opposing surfaces, the wires being connected at each end to a rotationally movable member capable of moving the wires along separate, concentric, orbital paths. The orbital movement at the ends of the wires is translated into linear movement where the wires engage and fold the yarn by a cam surface that engages and guides the wires along their separate linear paths. The wires are connected at their ends to a coil spring so that the length of the wire between the members can vary, all the time maintaining a minimum tension in the wires. Each member is rotated by a reversible stepping motor that is programmed to move its wire along a predetermined orbital path.
