Abstract: Membrane body (1) comprising at least one pair of panels (10, 11) connected together in an adhesive manner and for each pair of said panels (10, 11), at least one flexible sheath (15) arranged stably according to a set pattern to resist membrane stress acting on the panels (10, 11); each sheath (15) housing a respective tie rod (16), connected to the panels (10, 11) in an end position in a set manner in such a way as to be suitable for resisting normal stress to free the panels (10, 11) from the respective membrane stress, thereby maintaining the—group of the panels (10, 11) flexible and maintaining the corresponding production method.

Abstract: A method and a plant (1) for the production of a membrane body (10) that is flexible and able to assume a given shape under load; the membrane body being provided with at least one pair of flexible sheets (9) mutually coupled through an adhesive layer (14) positioned between mutually facing respective faces (16) of the sheets (9); the method comprising a step of die casting a portion (11) of given extension of the membrane body (10) to determine adhesion between the faces (16) and to form at least one sheath (22) with an external tubular portion of a respective cable (20); the step of die casting the portion (11) being achievable by thermal activation of the adhesive layer (14) in a static manner.
