A method and apparatus for moving workstations to perform work on a workpiece, includes moving workstations through a first path generally parallel to the workpiece and performing work on the workpiece. The workstation then returns along a second return path spaced further from the workpiece than the first path. The spacing between the plurality of workstations may be controlled such that sequential workstations work on the workpiece at predetermined intervals. Several embodiments of conveyors meeting the above-described broad features may be used.
