SYNCHRONIZING SYSTEM

摘要

A system for and a method of synchronizing the movement of serially connected drive and driven fluid motors employed to move electrostatic coating devices across articles to be coated. The electrostatic devices coat the articles with a protective and/or decorative coating material. Valve means is connected to a source of fluid under pressure and to a fluid input port of the drive fluid motor to control the direction of movement of the fluid motors and hence control movement of the electrostatic devices cooperatively associated with the fluid motors. Means, cooperatively associated with the fluid motors, which reacts to an imbalance in the movement of the fluid motors so as to cause balanced movement of the fluid motors so that the movement of the driven fluid motor is substantially synchronized with the movement of the drive fluid motor.
