The portable body (1), incorporating a pliable, inflatable casing (3), is arranged on a base. The casing is inflated and in the inflated state is tubular. A channel or tube-shaped mould part of the body is covered with the shapeless material. The mould part includes at least a part of the casing running in the peripheral direction of the casing, which part in a locating part locates against the base, in order to form the channel or tubular part, and the building material is allowed to set. This setting process is repeated until the required thickness is achieved in the channel or tubular part wall. Air is then vacated from the casing, the mould part is freed from the channel or tubular part and the body is removed. |
