Abstract
A moving part has material initially applied to it a predetermined distance from its leading edge. Whenever a sensor senses a notch in a flange of the moving part, application of material to the moving part is stopped for a predetermined distance prior to the start of the notch to a predetermined distance beyond the notch. Application of material to the moving part is finally stopped a predetermined distance prior to its trailing edge. Two separate sensors are used to control each of three spray guns for applying the material in the selected areas.
