ABSTRACT:
The invention relates to the use of a thin flexible track of spring steel having a series of perforations therethrough for use in conjunction with a variable speed travel carriage having a carriage drive sprocket which is studded about the periphery with balls or spherical members adapted to mesh with the track perforations to drive the carriage along. By this arrangement, greater loads may be driven than was hitherto possible with known flexible-track devices requiring the use of a guide and drive track following the contour of workpiece upon which work is being carried out.
