  • a third mode uses a differential that can handle multiple speeds. It is a differential mechanism with a connecting rod connected to a differential cage, whose combination of the two inputs, which are fed by a rake palpating a cam or by the movement, allows the tip of the needle to follow an arbitrary geometric trajectory imposed by the profile and the speed of rotation of the cam.
