S/Z cabling machine for laying fibers around a grooved pull-reliever

A cabling machine for laying optofibers, cables or other elongate elements into oscillating, waveshape grooves extruded around a pull-reliever to produce a finished article comprising a pull-reliever reeling-off device for reeling-off a pull-reliever in a first direction, a braking capstan located downstream of the pull-reliever reeling-off device in the first direction, a fiber reeling-off device located downstream of the braking capstan in the first direction for reeling-off fibers, an S/Z-bench located downstream of the fiber reeling-off device in the first direction for laying the fibers around the pull-reliever, a yarn spinner located downstream of the S/Z bench in the first direction for fixating the fibers on the pull-reliever, and a wheel capstan and a taking-up device located downstream of the spinner in the first direction for forwardly pulling and taking-up the finished article respectively, said S/Z bench including a laying-on tube provided with a laying-on head so that the fibers pass over the laying-on tube up to and through holes in the laying-on head, where the fibers are laid on the pull-reliever and fixated with yarn taken from the yarn spinner located immediately downstream of the laying-on head, the pull-reliever reeling-off device and the braking capstan being rotatably mounted;

• the laying-on tube being freely rotatable and being guided by way of the fibers being laid into the grooves in the pull-reliever;
• the laying-on tube being connected to a transmission;
• and a sensor connected to the transmission for detecting rotation of the laying-on tube caused by the oscillating, waveshape of the grooves in the pull-reliever and for causing the reeling-off device and the braking capstan to rotate and perform a correcting function which counteracts excessive rotation or twisting of the laying-on tube such that the grooves in the pull-reliever in a vicinity of the laying-on head will extend substantially rectilinearly and such that the fibers will extend substantially parallel with the laying-on tube in the absence of friction thereagainst.
