During the production of moulded bodies from a nonwoven ( 20 ) which can be solidified by a binding agent ( 11 ), differences in contour arise in critical profile regions of the moulded body using known methods. This especially occurs where the profile ( 26 ) has sharp curves or where the height of the profile sharply increases. According to the invention, moulded bodies having accurate profiles are produced by subjecting the nonwoven ( 20 ) to a suction process in points, i.e. at least in the critical profile regions, in the step of the method during which die form tool is closed. The air enclosed inside die nonwoven is thereby sucked out ( 37 ) and is used to position the fibre bundles on the contour of the form tool ( 25, 26 ) in an accurate manner. This enables an accurate embodiment of the moulded body to be obtained in terms of its contour, during cooling and hardening.
