  • Patent number: 7036663
    Abstract: A package of a roll, particularly a paper web roll comprising a wrapper, particularly a paper web wrapper wound stagewise into at least two wrappings about the roll in an overlap fashion. The paper web wrapper is wound about the roll in a slightly helical manner so that the edges of the wrapper layers overlap in a staggered fashion. The staggered edges of the overlap wrapping are formed so that each superposed wrapper layer conceals the underlying wrapper layer, whereby in a finished wrapping of a product only one wrapper edge remains visible.
