Abstract
Systems, including method and apparatus, for processing workpieces driven automatically along a linear path to a plurality of positions disposed substantially along the linear path. In some embodiments, a workpiece may be processed at one or more of the positions using two or more processing stations, such as a first processing station that cuts the workpiece into segments and a second processing station that performs another processing operation on the workpiece.
