Provided on a transfer table are guiderails that serve the linear guidance of the workpiece carrier in the “x” direction. Provided for each work station is a drive with a motor and a driving wheel that drives a double-sided toothed belt which in turn engages in a toothing of the workpiece carrier. A scale is arranged on the workpiece carrier and a stationary sensor form a position emitter whose signal enables the precise positioning of the workpiece carrier.
