Abstract
A mechanical, cam disk controlled zigzag sewing machine which provides an infinite zigzag adjustment device whereby a cam follower lifter restricts the zigzag width. The adjusting device returns to its initial position each time the cam follower lifter is actuated, i.e. when a new stitch pattern is selected. The adjustment device has the shape of a gradually rising cam profile and actuates a slide (31) which, by means of a finger (51), extends into the path of movement of the cam follower (48) in order to restrict the same with the result that the lateral movement of the needle is restricted in one direction.
