The apparatus also has a rotor with a monofilament guide hole wherein the rotor is revolvable or rotatable about the frame. An anchoring-warp-yarn heddle is disposed above the core cords and a foundation-warp-yarn heddle is disposed below the core cords. A hook lever is vertically movable and disposed before the foundation-weft-yarn carrier bar for pushing the outer core cords downward.
