Abstract
A jet apparatus has a body member having a yarn passage with a semi-circular cross section cut in one face, a single air orifice of diameter less than the yarn passage entering the yarn passage from the body side at an angle of 80.degree. to 90.degree. to the yarn passage, a cover plate secured by two screws and pivotable about one for stringup, and guides holding two yarns separated as they contact the yarn passage entrance. The jet apparatus is strung up passing two ends of false-twist-textured yarn separately into the yarn passage of the jet with the cover plate swung open while holding both running ends in a waste jet at a relatively high tension to keep the yarns separated in the yarn passage and finally closing and securing the jet cover. Turning on pressurized air to the jet and transferring both yarns simultaneously from the waste jet to a windup where they are wound at lower tension allow the two ends to combine together in the jet.
