ABSTRACT:
Thermoplastic yarn ends are spliced by overlapping side-by-side and spinning with an air jet circumferentially around a longitudinal axis of a cylindrical cavity with sufficient initial slack to insure engagement with the wall of said cavity. Heat is generated by the spinning action and concentrated in high twist nodal points giving rise to plasticization of the yarn and bonding of adjacent fibers. The spinning device has gripping elements for securing the yarn ends and introducing the necessary predetermined slack.
