ABSTRACT:
A machine for operating on a glass bottle. A carriage is displaceable by a servo motor having three lead lines. The rotation of the servo motor is stopped when power has been removed by shorting regenerative resistors to the three motor leads. The stopped servo motor is held at its stopped position by connecting a direct current power supply to two of the three servo motors.
