A method and apparatus which enables stranding a skein-like element with reduced backtwist characterized by a stranding nipple, a tubular store having an axis, means for rotating the tubular store on its axis in both a first and second rotational direction and means for moving the tubular store longitudinally along its axis as it is being rotated. The change in direction of rotation is selected to occur during displacement from an initial position spaced from the stranding nipple to a final position adjacent the stranding nipple so that during a first portion of a cycle, lays are accumulated on the tubular store then with reversing of the rotating direction, the lays are decreased and finally during a third portion of the cycle the tubular store is shifted from the final position back to the first position for repeating the cycle.
