ABSTRACT:
A spray application system for applying material to a surface of a rotating body such as a beverage can includes a detector that detects the actual speed of rotation of the surface during a spraying operation. This allows a controller to adjust trigger signals for the application device to be adjusted based on speed of rotation to minimize overcoat. A laser sensor may be used as an example. The use of the speed detector also allows for partial wraps as well as full wraps of applying material to the rotating surface.
