Abstract
A method and apparatus for splicing thermoplastic monofilament material by high frequency vibratory energy use a support having both forming means and an adjoining flash receiving cavity. Monofilaments to be spliced are disposed in the forming means in overlapping relationship. High frequency vibratory energy is applied to the overlap region softening the monofilaments while the excess thermoplastic material created during the splicing is extruded into the adjoining flash receiving cavity. The vibratory energy is removed and the softened material remaining in the forming means solidifies into a continuous monofilament having a predetermined cross sectional area.
