ABSTRACT:
To produce novel pattern designs differing from patterns which are available, a sewing machine comprising control segments stored in a pattern carrier and corresponding each to one sewing pattern formed by a group of stitches, a device for sensing the program carrier, and a device for controlling the needle and feed movements determining the pattern, is provided with a second program carrier including control segments for at least a single stitch, with the second program carrier being activatable through a selector switch between two consecutive steps of sensing one or more of the control segments of the first program carrier. In an electronically controlled sewing machine capable of storing in a programmable working storage any number of sewing patterns which can be sequentially recalled, a program carrier comprises at least one control segment which is associated with a single stitch and whose starting address can be stored in the working storage once or several times between addresses of control segments of the sewing patterns. If the additional control segment corresponds to a single backward stitch, a particularly great number of designs completely differing from the basic pattern can be produced.
