(54) Planetary 'SZ' twist accumulator


(57) An accumulator for twisting or stranding cable having planet gears (20) revolving around a sun gear (22). Each planet gear carries an accumulator roll (17) in a position spaced from the planet gear axis so that during rotation of the gears each accumulator roll travels alternately towards and away from the axis of the sun gear. The accumulator rolls move in synchronism and thus the accumulator capacity which is dictated by the distance between accumulator rolls, changes between maximum and minimum capacities dependent upon the accumulator roll movement. With two accumulators in series and operating with the accumulator rolls of one accumulator out of phase with the other by 180°, an 'SZ' twist is provided.
