  • Method and apparatus for preparing and splicing yarn ends
    Patent number: 4497165
    Abstract: A system for preparing and splicing two yarn ends has preparation nozzles in a turbulence chamber adjacent the end faces of a casing. The preparation nozzles improve the quality of the splicing by thinning the yarn ends. Compressed air or a partial vacuum can operate the preparation nozzles. With preparation of the yarn ends in the turbulence chamber for the splicing, the expenditure for a preparation mechanism remote from the splicing casing is eliminated.
