摘要

Process for compacting a pulverulent mixture (P) on a support (2) in order to obtain an applicator formed by the said support (2) provided with a pellet (23) of the compacted pulverulent mixture. Compacting is effected in an enclosure (11) in which a piston (3) slides, the piston (3) applying pressure to a layer of powder disposed at the bottom of the enclosure (11) and ultrasonic waves being emitted through the support (2) while the pressure is applied by the piston. The support (2) is provided with anfractuosities over at least part of its surface in contact with the pulverulent mixture.
