“…Due to the rapid development of the chemical industry, flexible rubberized fabric has now appeared as a new type of building material. Their properties: low weight, flexibility, the ability to change shape when the load changes, and high maneuverability, as shown in the works of T. Tomiyama and I. Nishizaki [12], Weston, G. Chartuni, L. Dalton, D. Force, J. Trovillion, K. Zyumbulev, R. Macmillan [13], Novikov S.G., Kutsenko V.N. [14], -create great prospects for their use as flexible organs in hydraulic water level regulators.…”
