摘要： A fabric position correcting device detects the position of at least one of an outer profile line and a pattern of a fabric portion corresponding to one of pressers, corrects the position of the fabric portion while holding the same whose position has been detected, and presses the fabric portion with the presser after the position thereof has been corrected. The aligning process composed of the above three steps is carried out four times successively with respect to fabric portions corresponding to the respective pressers from the leading end of the fabric in the direction in which it is fed. Then, the positionally corrected fabrics are fed to the sewing start position. Therefore, the positional correction of the fabrics relative to at least one of the outer profile line and the pattern thereof can be accurately, reliably, and automatically carried out from the leading end to trailing end of the fabrics.

The processing device has a detecting unit for detecting a color state of the pattern of the sheet material and producing a color state signal indicative of the color state. The processing device processes the sheet material on the basis of the color state signal produced by said detecting means. According to the present invention, the processing device is provided with an automatic adjusting unit for adjusting the detecting unit to allow the detecting unit to produce a desired color state signal with respect to a reference color state. Therefore, the white balance or the dynamic range is properly adjusted simply and reliably for the processing device.

摘要： A fabric position correcting device for correcting relative position of two fabrics in terms of alignment in at least one of outer profile lines and patterns of the fabrics. A pair of fabric holders are provided which respectively hold first and second fabrics. The holders are movable in X, Y directions, and angularly rotatable about a vertical axis for moving the respective fabrics. A pair of image sensors are provided for picking up at least one of outer profiles and patterns of the respective fabrics. Data from the image sensors are utilized for computation of moving distance and angular rotation angle of the holders in order to eliminate misalignment between two fabrics in terms of at least one of the profiles and patterns.
