Knitted-fabric sewing-machines, - The point ring 3 is rotated' at a uniform rate and the radially operated needle 2 is moved circumferentially at the same rate while in the work by a cam device. 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. The stitching strokes of the needle may be effected by any suitable mechanism.
