Abstract: The invention relates to automatic sewing and/or joining of textiles, high polymer materials, leather and metals. The object of the invention is to automate the sewing opertion system, to improve the quality of the seam and to conserve labor. A self-regulating system has to be created. According to the invention, the sewing operation is carried out as a control process, in which the deviation of the produced seam shape from the stored seam shape serves as a control value for the transporting elements of the sewing goods. For this, one or a plurality of detection heads and light emitters are arranged in the area of the seaming point, and are connected to an information processing system. The seam shape initially arising is transformed into storable data, is stored together with other data of the seam, and the seam path arising from automatic sewing is compared with the stored data. Deviations from the desired seam path are at once automatically corrected.
