  • Patent number: 4676483
    Abstract: A winch drum (1) is designed to operate without fleeting knives.The winching surface of the drum (1) is made up of fingers (6) which reciprocate axially along the drum (1) during use. The design is such that, in use, a major proportion of the fingers (6) are always moving in the same direction along the drum (1). This has the effect that the turns of an element being winched are both spaced and continuously progressed along the winching surface of the drum (1).The invention has particular application in the laying and taking up of submarine optical fibre cables.
