  • Patent number: 5221390
    Abstract: The present invention relates to a method for positioning at least one thread, band or like element in a pre-determined pattern above a conveyor path with the aid of thread outfeed device having at least one thread outlet device. In accordance with the invention, the thread outlet, or each thread outlet, is moved in a simple or a composite rotational path in a plane parallel with the conveyor path, and the path is moved linearly in relation to the rotational axis of the thread outlet. This will cause the thread outlet to move in a spiral-like movement path relative to the conveyor path. The conveyor path has mounted thereon dogging elements which are located within the spiral-like movement path of the thread outlet, such as to enable the thread to be laid out in a pattern determined by the dogging elements. The invention also relates to apparatus for carrying out the method.
