  • Method and apparatus for splicing yarns and tow
    Patent number: 4397140
    Abstract: A method and apparatus for interentangling ends of multi-filament yarn and tow which involves subjecting the overlapped ends to jets of gaseous fluid to interentangle the ends. The method involves employing a plurality of jets, one of which tends to rotate at least one of the filaments, and the other of which tends to move the filaments transversely. The jets act on the filaments when they are in motion from a previous jet. The apparatus provides a chamber for containing the overlapped ends and for defining the jets.
