  • Patent number: 4326632
    Abstract: A cylindrically shaped body of a two-component adhesive material includes at least one web wound spirally around a central axis so that the web forms a number of overlapping layers in the radical direction of the body. The two-component adhesive material includes a resin component and a hardener component. A layer of each component is coated on the web. When the web is wound it separates the layers of the two different components so that they do not intermix. The cylindrical body can be laterally enclosed in a sheath and/or its transverse ends can be capped or coated to prevent intermixing of the components.
