FIELD: process engineering.
SUBSTANCE: invention relates to production of composite material articles, namely envelopments of rotation for load bearing structures. Proposed device comprises casing with flange, cover with mating flange, forming mandrel with annular base accommodated inside aforesaid casing, and elastic diaphragm with annular collar that embraces said mandrel. Casing and cover flanges are jointed together via annular inserts arranged there between to receive elastic diaphragm and forming mandrel. Note here that seat made on the casing side receives elastic diaphragm collar while seat on the cover side receives mandrel base. Device incorporates also a number of annular inserts that differ in their ID.
EFFECT: compact design, ease of use, lower costs.
