Abstract: The invention refers to a method of manufacturing a pressure tank, comprising an inner container and an outer layer made of a fiber material which is wound around the inner container. In performing the method, a retention device with several retention elements protruding therefrom is attached to an inner container so as to wind a local pole cap reinforcement in a dome-shaped pole cap portion of the inner container. Then the retention device is removed and an outer layer is produced by winding of fiber material, the outer layer surrounding the central portion and the pole cap portions of the inner container.
