ABSTRACT:
A process for producing a yarn with alternate twist, which is obtained by intermittently varying the distance which the twist extends back upstream of a false twister. The variation in the distance is produced without braking the yarn and is achieved by means of a blocking device acting intermittently at a point located close to the false twister. The duration of action of the blocking device approximately corresponds to the time taken by a given point on the yarn to cover the distance from a delivery member to the false twister.
