PURPOSE: Many motors interlocks while maintaining different rotational frequencies to sustain the setup rotation rate automatically regardless of changes of surroundings when producing certain products. CONSTITUTION: Install the revolution detecting sensors (61,62,63,64,65) which output pulses proportioned to rotational frequency in the main drum (11) and other many sub drums (3,5,7,9) interlocking with the main drum. And set up the rotation rate of the sub motors (22, 23, 24, 25) for the main motor (21) in the microprocessor of the interlocking control parts (70). The microprocessor compares and analyzes the data from the rotation detecting sensors with the setup values and increases or decreases the current supply to motor to maintain an even rotation rate.
