Air spliced yarn and associated method and apparatus for forming the spliced yarn. The spliced yarn has the ends extending in a common direction laterally of the body of the yarn with the fiber components of the spliced ends of yarn being intimately entangled with each other and forming a commingled projection of entangled fiber components extending laterally from the body of the yarn. The spliced yarn is disclosed for connecting a running package of yarn to a reserve package of yarn as in a yarn creel feeding a bank of yarns to a carpet tufting machine. The apparatus comprises a hand held manually actuatable air valve for compressed air connected to a housing having a hollow wall. The housing has an open ended passageway therethrough for receiving side-by-side yarn ends facing in the same direction. A series of openings for entrance of compressed air into the passageway extend through the inner wall of the housing for effecting air entanglement of the ends of yarn positioned in the passageway.
A method of connecting packages of yarn to each other in a textile creel associated with a textile machine so that when one package of yarn is exhausted, another package of yarn can be used without stopping the textile machine, said method comprising providing alongside the creel hand carried manually actuatable air nozzle connected to a pressurized air hose and having a yarn air splicer mounted on and communicating with the air nozzle, the air splicer having a housing with an open ended passageway therethrough surrounded by an air chamber in the walls of the housing communicating with the passageway through a series of circularly arranged openings, air splicing the tail end of the running package of yarn to the leading end of a reserve package of yarn by simultaneously placing with one hand the tail and leading ends of the yarns extending from the packages of yarn into the passageway extending through the air splicer with the ends of the yarns being beside each other and facing in a common direction, and while with the other hand holding and manually actuating the air nozzle to direct pressurized air into the air splicer and through the series of circularly arranged openings therein and into the passageway extending therethrough for subjecting the ends of the yarns therein to air turbulences to effect an entanglement of the fiber components of the ends of the yarns with each other and to impart twist to the entangled ends of the yarns so as to form a twisted commingled projection of entangled fiber components extending laterally from the joined yarns.
A textile creel comprising a plurality of creel units spaced apart from each other and defining aisles therebetween, each creel unit having tiers of yarn packages thereon with the yarn packages arranged in cooperating pairs from which the yarn of one package of each pair is adapted to be directed to a textile machine, a source of pressurized air medially located in each aisle, a hose in each aisle having one end connected to a respective source of said pressurized air, a hand held valve having an inlet end and an outlet end, said inlet end being connected to the other end of each respective hose, an air operable yarn splicer connected to said outlet end of said valve, said yarn splicer comprising a housing having an open ended passageway therethrough, said passageway having an inlet and an exit end, the inlet end serving to receive ends of yarn to be spliced with the ends of yarn being positioned beside each other and facing in a common direction in the inlet end, the exit end serving for exhaust of the compressed air, said housing having inner and outer walls defining an air chamber therebetween, an opening in said outer wall connected to said outlet end of said valve, and a series of openings for compressed air extending through said inner wall and communicating with said air chamber and said passageway for effecting air entanglement of the ends of yarn positioned in the passageway.
