ABSTRACT:
A method and apparatus are provided for automatically sewing an advancing workpiece. To facilitate subsequent sewing operations, the workpiece length is calculated as the workpiece moves along its predetermined path of travel. If the advancing workpiece length lies within a preselected range of sizes, the workpiece will continue to move along its predetermined path. Should the workpiece length be calculated to be outside the preselected range of sizes, the workpiece is rejected from the predetermined path of travel.
