Abstract
A thread cabling machine is provided with an improved regulator device (or cabling head) in which each work station consists of a DT unit similar to a double-twist unwinding spindle which enables two elementary threads to be united by twisting. One of the threads forms a balloon which surrounds the bowl inside which the spool of the second thread is disposed. The two threads are joined on a cabling head consisting of a unit comprising two pulleys mounted on a support driven rotationally by the balloon of the thread. The invention is characterized in that the eye carrier plate, disposed under the rotary pulleys and enabling the threads to be brought to the pulleys, is provided with a frustoconical part enabling the thread forming the external balloon to wind around a reserve groove forming a radius 'r' relative to the axis X--X of the unit.
