  • Patent number: 7445811
    Abstract: A method and an arrangement in a coating line for a fibre-like product or fibre-like products, in which the fibre-like product is directed from output means to a press head, by means of which a tube is formed around the fibre-like product. The fibre-like product is directed from the coating line to a feed unit in a preparatory position at the side. When the coating process of a previous product has terminated, the feed unit is shifted to the coating line and the fibre-like product is fed into the press head and is accelerated to the speed of the tube by means of the feed unit. The feed unit is detached from the fibre-like product, when measurement parameters associated with the fibre-like product and/or the tube reach the predetermined values and is shifted back to the preparatory position at the side of the coating line.

  • 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.

  • Patent number: 5716017
    Abstract: A method and arrangement in connection with a continuously operating spooler is provided, in which the thread to be spooled is arranged to be guided onto an empty reel after a first reel has become full by means of a moving finger and a gripper rotating with the empty reel. The thread to be spooled is moved using the finger, into the path of the gripper. The movement of the thread carried out by means of the finger is synchronized with the movement of the gripper in such a manner that the finger manages to move the thread into the path of the gripper before the gripper reaches the meeting point of the gripper and the thread.
