Abstract: A method of and apparatus for controlling spinning machines comprising circulating a working machine having a detector along a rail for monitoring the running conditions of the spinning machines in which a transmitter provided in the working machine transmits a first information signal indicating the nature of possible abnormal conditions of each spinning machine to a remote station having a receiver and a computer. In the receiver, a second information signal is generated and successively stored in registers depending on the nature of the abnormal conditions in accordance with the first information signal received. The computer reads the contents of the registers only when an interrupt signal is generated which indicates that an abnormal condition has occurred in a particular spinning machine. The computer memory tabulates these data and updates the data each time the working machine circulates around the spinning machines.
