摘要： An automatic sewing machine is disclosed which includes a position control device or a device to align automatically the edges of sheet materials to be joined as they are fed toward the needle. The device comprises a sensor unit for detecting the side edges of the upper and lower sheet materials to be joined, a manipulator unit comprising a pair of upper and lower manipulator arms which displace traversely the upper and lower sheet materials independently of each so as to align the side edges thereof, and a control unit which controls the timing of the operation of the manipulator unit to the operations of various mechanisms of the sewing machine such as an automatic feed reverse mechanism, an automatic thread cutting mechanism and so on. The seam formed is spaced apart from the aligned edges exactly by a predetermined distance or margin which may be selectively varied.

摘要： 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.
