Abstract
A sewing machine employing a stepper driven-stitch patterning mechanism including a stepper rotated cam with a spiral cam groove tracked by a follower formed with different cross sectional shape than the cam groove in order to provide only point contact with each side of the cam groove when spring biased therein. A spring arrangement biases the cam and follower together in a direction perpendicular to the axis of cam rotation, thus minimizing lost motion between cam and follower.
