A device for sewing together two fabric parts includes two pattern sensors and correcting means for determining and correcting misalignment of patterns on the fabric parts. Also, an additional image sensor (18) is provided, which scans the surface of the fabric (16) to be sewn at the site of an intermediate storage location (15) before this fabric is fed into the sewing machine. An image-processing device connected to this additional image sensor generates data on certain basic characteristics of the fabric pattern, such as color, contrast, lightness, register length, and angular orientation of the pattern components. From these characteristic data, a decision logic circuit determines setting data for the operating parameters of the devices used in the sewing machine for detecting and correcting a possible pattern misalignment during sewing.
