Abstract: A system for the edge-parallel sewing of a workpiece, consisting of a plurality of layers, together to form a seam, e.g. in the production of trouser legs, pockets, shirts and the like, comprises a workpiece guide in the region of the needle path and formed with separators interposed between the layers, and a drag-clamping device which engages a portion of the stack of fabric layers remote from the incipient stitching operation to apply a stretching or drag force thereto. According to the invention, a retracting device is provided which, upon approach of the drag clamp to the stitching location, withdraws the guide device out of the path of the clamp.
