Abstract
A method and the device for minimizing stitching faults in embroidery devices (1) is provided, which includes a drive for moving the material holder (13), with an article to be sewn (11) being stretched therein, based on the knowledge that such stitching faults frequently can be explained by oscillations of the article to be sewn (11) and the material holder (13) due to rapid accelerations. Various effects, such as different types of articles to be sewn, changing weights, and friction ratios can cause a change of the oscillation behavior. One or more sensors (29, 43, 44) are provided and arranged such that they can detect the oscillation of the article to be sewn (11) and/or the material holder (13). The control of the drive and/or the sewing needle (23) occurs depending on the detected oscillations such that deviations of the stitching site from the predetermined target value is minimized.
