The needle-frame is connected to a rod 5 operated by a cam 6 formed for two-thirds of its circumference as an archimedean spiral by which the needle is displaced against the tension of a spring 7, the remaining third of the circumference being formed to allow the steady return of the needle frame to zero position.
