摘要： A pulse generator for a sewing machine drive, having a shaft revolving synchronously with the main shaft of the sewing machine. The pulse generator shaft is connected with two support elements which carry a strobe disk provided with control segments of bright and dark zones, the strobe disk extends between pairs of light emitting and light receiving components. The strobe disk includes a first partial disk non-rotationally connected with one support element and a second partial disk arranged adjacent and non-rotationally connected with the other support element, the angle regions of the mutually correlated bright and dark zones of the control segments of the two partial disks differing from each other, one support element being rotatable relative to the other support element, so as to change the bright and dark zones of the strobe disk.

摘要： A workpiece fed to a stitching point of a sewing machine, consisting of one or more layers of fabric, is transluminated by a source of visible or infrared radiation which is intercepted by two photoelectric sensors following each other in the direction of motion. The sensors work into respective radiation/frequency converters whose output voltages, after rectification, are compared in a window discriminator to provide an indication of the passage of a leading or trailing edge of a fabric layer manifesting itself in a jump in one of the voltages. The jump is intensified by a threshold circuit in each converter, comprising a Zener diode which for highly light-transmissive fabric layers can be short-circuited by an optocoupler.

摘要： Sensor including a non-contact proximity sensor, proportional change detector system and a sample gate. The machine logic program of the Automatic Sewing System generates a signal which enables the sample gate, at given times during the work cycle. The sample gate also receives a signal indicating fabric discontinuities which is generated by the sensor element. When such input signals are present, at the sample gate, an output is generated thereby to overcome the fabric discontinuities problem.
