The calculated values of the angular velocities of the layout and the winding are entered as a code into the permanent memory of the program control unit 2 and, during operation, the devices are used as program values.

In order to maintain the specified angular velocities of the pickup and winding in the process of device operation, pulses from sensors 5 and 6 at a certain time interval specified by software are sent to the counting inputs of programmable timer 9 of synchronizer 5, and from the output of synchronizer 5 to the input of software control unit 2 the codes are received corresponding to the number of pulses read.

and to the other input of the software control unit 2, pulses are sent only from the sensor 4. In the software control unit 2, the codes are processed and the current values of the winding and pickup speeds are calculated.

In case of deviation of the current values of the angular speeds of winding and pickup from the calculated values indicated in the ROM of the program control unit 2, the program control unit 2 corrects the code of the pickup speed by the value + P.

This value ± Pr code corrections from the ROM of the software control unit 2 through the code outputs is fed to the inputs of the digital-to-analog converter 13 of the synchronizer 15, which generates a speed increase signal. This signal is fed to the input of the operational amplifier 14 and through the diode optocoupler 15 is fed to the second input of the electric drive 3 of the pickup. The motor of the electric drive 3 of the layout processes the error signal and sets the speed of the layout, which is required for a given time, in accordance with formula (1). During the subsequent reading of the current values of the signals from sensors 4 and 6 at each coil unit, the program control unit 2 continuously adjusts the rate of pickup, thereby not complying with the current value of the winding speed in accordance with formula (1) or (2).

The laws of motion of the handler are formed as follows.

In the reverse mode, the pickup drive changes the direction of speed from + (x) nc, to - beg. The command for reversing the drive of the pickup is generated with the software control unit 2 at an angle dp until the end of the last turn. The magnitude of the angle oip is a function of wire diameter, pickup speed and drive characteristics and is determined by the expression

The command for the wire transition mode from section to section is generated by software control unit 2 at an angle d until the end of the last turn in the section.
