ABSTRACT:
For a method to control an automatic embroidery machine, the individual picture elements are copied from a motif carrier at hand and are transferred as an embroidery program to a storage element. To control the automatic embroidery machine automatically, according to the motif, it is provided that the motif, which has been converted to half-tones, is recorded line-by-line as a scannable picture, wherein, if need be, a color-specific picture with scannable half-tones is recorded for each color with color motifs; each picture is line-scanned, and each picture element, which represents a half-tone of optional intensity, is compared to an adjustable half-tone barrier or a fixed half-tone window, and is thus classified as being either lighter or darker and/or inside or outside of the half-tone window and is thus converted to a binary value; these binary values are stored and fed into a digital computer, which stores conversion programs for embroidery techniques, the motif, which has been converted to binary values, is composed section-by-section from the stored picture forms and the embroidery program, set up by the digital computer, is output to the automatic embroidery machine.
