ABSTRACT:
An apparatus for tying a knot in the ends of a pair of filaments or yarns comprising a hollow element having an open end and an opening adjacent to the open end, the opening and the open end being connected by a slot. A second element movable relative to the first element is provided with a projection for engaging the ends of the pair of filaments or yarns and wrapping these ends around the hollow element in such a manner that a first wrap lies over the slot and a second wrap lies over the opening. A first hook movably mounted on the second element is provided for engaging the second wrap lying across the opening and pulling it out through the open end of the first element to form a knot in the filaments, while a second hook is provided for engaging that portion of the yarn extending across the slot and moving it to a position adjacent to a filament clamp holding the filaments. The first hook is adapted to clamp the ends of the filaments and apply tension, when manually moved, to tighten the knot on the second hook.
