Abstract (en)
[origin: WO2014207325A1] The invention relates to a method for making a hollow object from a material that comprises threads (14, 15, 16, 17, 18) mechanically connected together in order to form a first shell (1). The method comprises a reference step that comprises shaping the first shell (1) on a carrier (21), a first step following the reference step and comprising covering the first shell (1) with a sealed membrane (22) and producing a pressure difference on either side of the membrane, wherein the pressure on the side of a surface of the membrane that is in contact (23) with the first shell is lower than the pressure on the side of a free surface (24) of the membrane, and a second step, simultaneous with and/or after the previous first step, that comprises causing a change of state and/or the bonding of some or all of the threads that make up the first shell.
