Abstract
The invention relates to textile machine control. The run of spinning units is controlled by two busses, a two-way bus, and a reserve one-way bus, the latter being activated, as a rule, by a central electronic system, and possibly, though less often, by the operator. A suitable arrangement of the circuits on the criterion of whether they belong to the two-way bus or to the one-way one, facilitates troubleshooting and permits shorter repair time on vast systems comprising a plurality of work stations of the textile machine. The invention can be used on various types of spinning machines where a predetermined length of wound yarn is required.
