ABSTRACT:
Apparatus as for use on a sewing machine, employing a stock pivoting and advancing platform for directionally guiding while advancing stock relative to a reference point during performance of an operation on said stock, the operation being therefore in a controlled pattern. Normally, a working tool such as a stitching needle, is at the reference point. The stock is incrementally advanced while repeatedly and incrementally being pivoted by the special platform in response to sensing of the pattern such as an edge of the stock. In use on a sewing machine, both the advancement and the pivoting are conducted while the stitching needle penetrates the material.
