ABSTRACT:
A method is disclosed in which all patterns to be sewn by an electronic sewing machine are divided into individual unit patterns. Stitch data characteristic of common unit patterns which find application in more than one pattern to be sewn is stored only once in a read-only memory. As a result, wasted space in a read-only memory caused by unnecessary repeated storage of the same stitch data pertaining to common unit patterns is eliminated. This method makes it possible to store more patterns within a read-only memory of a given size and further enables more complicated patterns to be sewn.
