ABSTRACT:
A rigid mandrel has a plurality of elongated sector pieces arranged in an edge-to-edge relationship to provide a peripheral wall for forming a hollow shell. One or more bladders are inflated within the peripheral wall by a pressurized fluid and edge portions of the sector pieces are configured to interlockingly engage corresponding edge portions of adjacent sector pieces when the bladder is in its fully inflated condition to form connecting joints which retain the sector pieces in a substantially rigid predetermined configuration corresponding to the peripheral wall. The connecting joints permit the sector pieces to be separated when the bladder is in a deflated condition, and a mandrel member provides an opening for removing the separated sector pieces from an interior chamber of the shell after the forming thereof.
