ABSTRACT:
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.
