ABSTRACT:
An automatic sewing machine includes a sewing machine mechanism having a seam forming mechanism and a fabric feed mechanism. A detector member senses the position of each free side edge of two layers of fabric to be fed to the seam forming mechanism and generates signals. A pair of manipulators capable of engaging each layer of fabric individually move such each layer of fabric to a predetermined position in response to signals from the detector members. The free side edges of layers of fabric are automatically stitched together by a predetermined distance along the free side edges with the edges maintained in alignment with each other.
