Abstract
Surface treating apparatus employing at least two linear motors driving a multiple linkage system for positioning the outlet of treatment apparatus such as a radiation head or a sprayer for coating objects and especially large objects. A combination of different motions such as linear, rotational and a combination thereof are achieved through varying relative speeds and/or selective movements of the linear motors used to drive the multiple linkage system. Treatment of the entire surface area of the item being treated is accomplished through with the number of reduced number of components of simplified design. One dimensional and two dimensional linear motors may be employed in the system. A second embodiment has a plurality of spray assemblies. Each assembly has a single arm and linear motor which moves along two perpendicular axes.
