Abstract
PURPOSE: To rapidly correct pattern deviation by providing a correction means for increasing or reducing a correction feed speed by a speed change means based on the detected result of a detection means for detecting whether or not the deviation of a pattern is corrected. CONSTITUTION: When the working cloths 12a and 12b of the same pattern are passed through a cloth guiding device 18 and set on a working cloth supporting surface 11, a value slightly larger than the maximum one of the edge intervals of adjacent horizontal patterns is inputted by a pattern interval key 87 as a stipulated length L and this sewing machine is operated, the deviation of the pattern between upper and lower working cloths 12a and 12b is detected when the sewing of the stipulated length L is ended, a pulse motor for upper feed adjustment is controlled so as to be rotated for a prescribed amount as needed and an upper feed speed is changed. Then, in the case that deviation amount correction is insufficient or excessive even when the feed speed is changed, the feed speed of an upper feed dog 57 is corrected, the feed speed of the upper feed dog 57 is immediately restored to an initial set speed when the deviation is corrected and sewing is performed in a state without the pattern deviation.
