An apparatus for adjusting the gap between lips of a die for extruding a plastic sheet material. A pair of flat plates spaced from each other have a plurality of bolts for controlling the gap. The operational adjustment of each bolt is generated as an electric signal, and this electric signal is added with reference to all the bolts to distribute the gaps between the die lips. Each adjustment is changed so that the distribution of the gap between the die lips acquires a predetermined form to thereby determine the necessary amount of adjustment of each bolt.

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. Thus, by counting the data in the memory, the running conditions of the spinning machines can be effectively monitored. Furthermore, the number of inputs to the computer can be effectively reduced by limiting the input data to the computer to a minimum.
