ABSTRACT:
Deflection members for threads, particularly for a hollow spindle machine. The members are movable in translation by a displacement device, from a first position, during normal functioning of the machine, in which each thread (2) is no longer in contact with the corresponding deflection member, and thus with the corresponding twisting device (3), to a second position during the phases of acceleration, deceleration and stoppage of the machine, in which each thread (2) is then applied by the deflection member (1) with which it is in contact, against the corresponding twisting device (3). The thread thus receives during only these three phases, the false tension necessary to impart to it at that time constant tension and winding independent of the speed of thread travel.
