Abstract
A method for operating a textile machine producing cross-wound packages has a multiplicity of autonomous work stations that each have a spinning apparatus and a winding apparatus and are equipped with a suction nozzle, connected to the vacuum network of the textile machine, for receiving a thread from the surface of a cross-wound package, and also a storage nozzle, likewise connected to the vacuum network, for temporarily storing excess thread length, and which is operated at least by one service unit that exchanges full cross-wound packages for empty tubes as required. The invention provides for the actuation of a cross-wound package/empty tube exchange by one of the service units to be prevented during the operations of restarting of the work stations, thereby ensuring that, during the restarting of the autonomous work stations, the maximum number of work stations always starts up again at the same time.
