  • Device and method for changing elongated objects
    Patent number: 8904683
    Abstract: A device for successively changing elongated flexible objects from an active viewable position to a non-active, non-viewable position includes a rotatable drum to which the flexible objects are attached, a motor driving the rotatable drum in opposing rotational directions, and a controller unit controlling motor speed and direction. A balancing spring is preloaded when the flexible objects are unwound from the drum, providing a lifting force when the flexible objects are wound up on the drum. By using a freewheeling clutch, preloading only occurs in one rotational direction, the balancing spring freewheeling in the other direction, taking no load. Utilizing a magnetically interactive identification strip the device gains highly accurate information on the position of the flexible elongated objects. By pre-attaching the flexible elongated objects on each other and providing the identification strip on the designated carrier flexible object exchanging the set of flexible elongated objects is made very simple.
