ABSTRACT:
A motor-driven sewing machine and method of making the same that includes a needle movable between advanced and retracted positions through a sewing station, a mechanism for controllably advancing the peripheral portion of a work piece past the sewing point and a mechanism for causing the sewing machine to apply stitches to the work piece border as the work piece automatically moves through the sewing station. The sewing machine is provided with a specifically configured feed dog and a presser foot which controllably moves the work piece along a work piece fence surface so that precisely configured stitches are expeditiously formed along the border of the work piece.
