in such a way that it can be automatically deactivated at vertical rows rails of winding heads without threads on the basis of presence monitoring by the thread tension sensors or the thread monitors it is always known by means of the thread tension sensors or the thread monitors which winding heads are not loaded as indicated in fig7 the lower brake disks of the individual thread brakes could however each also be rotated by an individual drive motor 40 u2032 in such a case each motor 40 u2032 is deactivated when the thread brake is not guiding any thread in addition to this a visual signal element 26 and an acknowledgment switch are also allocated to each winding head which serves as a bobbin placement aid and which therefore facilitates the fitting of the bobbin creel the signal element serves to place the different bobbin characters or bobbin types without errors in accordance with the specified repeats this also allows for the individual thread tension specified values to be allocated automatically to the corresponding thread types each vertical row rail is provided with an electronic node 29 29 u2032 which can process different signals by means of a serial line system 28 each side of the creel is provided with its own main processor 30 30 u2032 the activities of which can be co ordinated by means of a transfer processor 31 this also allows for one side of the creel to be controlled individually the thread tension specified values can be input per thread per thread group or rail by rail on a display unit the specified values which are input are passed on by the transfer processor to the main processors 30 and 30 u2032.
