Abstract
In an electrically controlled sewing machine equipped with means for varying the feed and the needle position for individual stitches and with a program storage for storing consecutive sewing programs, the display is made easily understandable and the display unit remains a compact structure by providing alphanumeric display elements in a sequence and means for switching the display unit into a first state, in which a basic setting of the pattern is indicated in symbols, and into a second state in which the patterns can be indicated in the sequential order of their storage.
