摘要： One or more embodiments relate to a device configured to form at least partially at least one disc of a wheel having a rim and a hub support defining an axis of rotation, wherein the device has at least: one central zone; one peripheral zone partially surrounding the central zone; one first portion having at least one first layer and extending into the peripheral zone and into the central zone along a first axis; one second portion having at least one second layer and extending into the peripheral zone and into the central zone along a second axis different from the first axis; and in that the first portion and the second portion are superposed relative to one another at the level of the central zone defining a stack.

摘要： A method and apparatus for shaping, compacting, and supporting a composite material (C) contained between two flexible membranes (G, F) and capable of being stretched over a porous mold (A) are described. The apparatus enables the use of inexpensive mold despite the high pressures used. A counter-mold (M) having the same characteristics as the mold can be used in certain instances. The equipment enables the use of a plurality of molds and counter-molds during one manufacturing cycle.
