摘要

Parts of a vehicle body such as the body sills are coated whilst the body is being conveyed along a production line by directing an unatomised jet (18a), (18b) of paint towards the boundary of the region (9) to be painted, to define a rectilinear boundary line, spray guns (8a), (8b) being used to paint the remainder of the region and compressed air from an air nozzle (20) being used to give a vertical paint edge at the end of the region to be painted. Sensors (5), (7), (14) are provided to automatically detect the present of a body, and/or the width of a body and/or particular features on the body which are used as reference features for control purposes.
