Abstract
An apparatus for joining together a plurality of sets of ends of yarn includes a housing having a plurality of splicing bores communicating with at least one passageway which selectively communicates with a pressurized fluid source. A set, preferably a pair, of yarns are placed in each splicing bore. A cutting member is utilized to cut the yams while within the bore so there are two yarn ends to be joined within the bore. The pressurized fluid source is then placed into communication with the bore and the splicing process begins. The yarns may be moved relative to the axis of the bore during the splicing process with a wiping bar. The pressurized fluid source may then be selectively removed from communication with the splicing bore to complete the splicing process. The sets of yarn will then preferably be represented as continuous strands of yarn entangled, intertwined, and/or twisted at the splice joints.
