    摘要: An apparatus for inserting twist into a moving strand, including a first body including an orifice extending therethrough for permitting passage of a moving yarn. An air channel extends therethrough and communicates with the orifice. The air channel communicates with the orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice. The first body is adapted for being inverted relative to, and placed in overlying registration with, a second like body whereby the air channel of the first body inserts one predetermined direction of twist into the yarn and the air channel of the second body inserts another predetermined direction of twist into the yarn.

    摘要: A process of producing an assembled yarn, including the steps of providing two or more yarns moving downstream from a supply to a take-up, inserting alternating-direction zones of twist into at least one of the yarns, the at least one yarn having an area of zero twist between said alternating direction zones of twist, combining the at least two yarns to form a single, integrated yarn strand, and intermittently exposing the yarn strand to an air blast to create a zone of intermingled yarns at spaced-apart points along the length of the yarn strand to prevent torsional movement of one yarn relative to the other yarn. According to one preferred embodiment of the invention, the step of exposing the yarn strand to an air blast includes the step of intermingling the yarns at the areas of zero twist.
