communication line 23 in another embodiment provision can be made for a communication tie link 23 u2032 directly between the machine control 20 and the evaluation unit 24 the communication line 23 is however to be preferred since this relieves the central machine control 20 of nothing more than simple data passage from the bus 25 to the said evaluation unit 24 further the evaluation unit 24 can be installed spatially independently of the machine control 20 in addition on the machine bus 25 and connected by communication line 27 is a service cart 26 with a start up aggregate for the spinning machine 10 additionally although not shown here startup robots are likewise connected by communication line to the machine bus 25 the spinning stations 41 a d are combined groupwise in a section 30 a d whereby in fig1 only the spinning stations 41 a d and the section 30 a are shown in detail each section includes a section controller 31 a d whereby each section controller 31 a d is connected respectively by communication line 32 a d to the machine bus 25 each section controller 31 a d also exercises a router function for the data exchange between a section bus 40 and the machine bus 25 in this way the section bus 40 is controlled from the section controller 31 a a section electronic device 42 as well as a thread cleaner 43 is assigned to each spinning station 41 a d each spinning station 41 a d is connected by a communication line 62 a d to the section bus 40 to each section electronic device 42 for example.
