Patent

CA 2605285

The invention relates to a device and a method for filling a molded article that comprises a plurality of at least partially communicating interior cavities with a liquid phase or for removing the excess of a liquid phase used to coat a molded article comprising interior cavities. The inventive method is characterized in that filling or removal of the excess from the interior cavities is carried out by way of an acceleration process and a subsequent braking process, deceleration being faster than the previous acceleration, with the proviso that the inertial forces caused by deceleration and acting upon the excess liquid phase are higher than the sum of the other opposite forces also acting upon the liquid phase.

La présente invention concerne un dispositif et un procédé pour remplir d'une phase liquide un corps moulé présentant une pluralité de cavités internes, reliées au moins partiellement les unes aux autres, ou pour éliminer l'excédent d'une phase liquide utilisée pour enduire un corps moulé présentant des cavités internes. L'invention se caractérise en ce que le remplissage des cavités internes ou l'élimination de l'excédent de ces dernières est effectué(e) par un processus d'accélération et un processus de freinage suivant, la décélération se produisant plus rapidement que l'accélération produite préalablement, dans la mesure où les forces d'inertie, induites par la décélération et agissant sur la phase liquide en excédent, sont supérieures à la somme des autres forces opposées agissant également sur la phase liquide.
