Abstract:
A method for inserting twist into a moving strand, comprising the steps of:(a) providing first and second discs, each of which include: (i) an orifice extending therethrough for permitting passage of a moving yarn; (ii) an air channel extending therethrough and communicating with said 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; (b) inverting said first disk relative to said second disk and placing said first body in overlying mating alignment with said second disk; (c) passing a strand of yarn through an orifice in said first disk and an aligned orifice in said second disk; (d) directing a cyclonic air circulation pattern into an orifice in the first disk in a first predetermined direction for inserting a corresponding first direction of twist into the yarn; (e) directing a cyclonic air circulation pattern into an orifice in the second disk in a second predetermined direction for inserting a corresponding second direction of twist into the yarn.
