NAEHMASCHINE ZUR HERSTELLUNG EINES NAEHMUSTERS

A sewing machine has an electronic control for the production of at least one stitch pattern consisting of a plurality of different single stitches, with a read-and-write memory RAM for storing in memory at least the single stitches of the stitch pattern and with a feed mechanism whose feed adjustment occurs by a step motor controlled in accordance with the stored data of the read-and-write memory within the inactive phase of the feed mechanism. To carry out a feed variation exceeding the maximum number of steps of the step motor between two predetermined sewing stitches, the control unit contains a comparator which compares the magnitude of the displacement amount of the step motor before the next displacing movement is carried out with a given maximum displacement amount, in order to prevent a stitch formation between the point of insertion of the previous stitch and the desired point of insertion of the next following stitch when the maximum displacement amount is exceded.
