DEVICE AND METHOD FOR CHANGING EMBROIDERY PATTERNS

A method and the device for scaling or changing embroidery patterns ( 1 ) for sewing machines that allows a quick calculation of optimized stitching data. For one or more different change factors qj, data sets dj with optimized stitching data (xji,yji) are stored. A target data set z with stitching data changed according to a given change value v is determined by selecting one of the stored data sets dj and performing an extrapolation or an interpolation with the associated stitching data (xji,yji). For a pattern with several sub-patterns, these sub-patterns can be changed individually and combined to form a changed pattern.
