  • Patent number: 6334586
    Abstract: The invention relates to a method and arrangement to be used in connection with spooling a cable or the like with a double spooler, in which method spooling begins onto a first drum and, at a desired stage, spooling changes over onto a second drum. To simplify operations associated with spooling, simultaneously while spooling continues onto a second drum, the actuators in connection with the first drum are controlled to unwind cable off the first drum into a place provided.
