ABSTRACT:
A sewing machine is disclosed wherein the positional coordinates for successive stitch penetrations are stored in a memory having addressable locations corresponding to a plurality of operator selectable patterns. Means are provided for operator initiation of an override command to selectively alter the operation of the feed and bight actuators to an amount of motion different from that dictated by the stored pattern information. An operator influenced control provides a digital signal corresponding to a desired alteration value. Override memory locations are provided for storing bight and feed actuator motion alteration values. These locations are addressed in accordance with the selected pattern and the digital override signal provided by the operator. The alteration values are utilized for control of the appropriate feed and bight actuators.
