The invention relates to a process and a device for automatically executing a seam end portion, so that the latter terminates at a constant distance from the edge of the fabric, of which the passage in line with a fixed point is detected by a sensor 20, 21. According to the invention, during a recording operation, the number of pulses 33 counted when the signal emitted by the sensor 20, 21 occurs and the final number of pulses are memorised, and during the reproduction the number of counted pulses 37 has substituted for it the number of pulses 33 recorded when the signal from the sensor 20, 21 occurs, and the number of pulses thus reinitialised is compared with the final number of pulses 35, in order to command the execution by the sewing machine 10 of complete stitches and, where appropriate, of a last stitch reduced according to the results of the comparison. The invention is used in the garment manufacturing industry. <IMAGE>
