摘要： A method for approaching a predeterminable end point of a seam spaced from the edge of a workpiece, with a sewing machine which comprises an adjustable needle and lower transport, a sensor arranged before the needle and triggering the process for the positioning of the needle in the end point during passage through the edge, a pulse generator coupled with the main shaft of the sewing machine for the delivery of counting pulses for a pulse counter, and a micro-computer which controls the action of the feed means as a function of the pulses originating from the sensor and from the pulse generator. To execute a desired shortening of the length of one or more of the last stitches before the end point of a seam, the workpiece is moved back by the difference between the desired stitch length and the stitch length set by the setting device, before execution of the adjusted feed. For correction of the stitch length executed during the feed phase, the cloth feeder is connected with a switching gear controlled by the micro-computer for controlled switching on during its reversed feed phase which precedes the respective forward feed phase.

摘要： Method and apparatus for electro-pneumatic control of a stitching machine, operable either in the automatic or semiautomatic mode. Following initiation of a stitching operation through actuation of the present control system, the system internally of itself develops a plurality of interlocks that require the existence of selected conditions for continuation of normal machine operations and which respond to abnormal conditions by precluding machine operation past preselected termination points. Thread conservation is a principal benefit.

摘要： A sewing machine having an edge guide for producing a stitched seam along an edge of a workpiece terminating at another edge forming an angle with the first has an optical device for directing a pencil or beam of light toward a reflective surface which underlies the workpiece and is covered thereby until the movement of the workpiece exposes the reflective surface at this other edge. The optical detector then produces a signal for initiating a control function, e.g. the change of stitch pattern to tie off the end of the previously sewn seam or to lodge the needle in the fabric so that the workpiece may be turned to bring the other edge into contact with the edge guide. The control system can include a programmer for the successive stitching operations which are initiated in succession in response to the optical sensor.

摘要： A sewing machine is disclosed in which electromechanical actuators are incorporated. By selectively supplying power to position the electromechanical actuators, the stitch forming instrumentalities of the sewing machine may be operatively controlled. In order to reduce heat dissipation within the sewing machine under abnormal conditions where the actuators are locked for long periods of time, the sewing machine main drive motor motion is monitored. After a predetermined period of inactivity of the sewing machine main drive motor, the power which can be supplied to the actuators is limited.

摘要： A sewing machine operated by a foot controller is provided with a mechanism for stopping the main shaft of the sewing machine in a predetermined position of each revolution thereof, thus to intermittently drive the sewing machine to produce intermittent stitches. The mechanism can be made inoperative allowing the main shaft to continuously rotate, thereby to produce the ordinary continuous stitches.
