Abstract

La présente invention porte sur un traitement à la grenaille au moyen duquel il est possible de réduire le temps total de traitement. Une pièce à travailler (W) est transportée au moyen d'un transporteur à rouleaux d'entrée (12). La pièce à travailler (W) située sur le transporteur à rouleaux d'entrée (12) est introduite dans une chambre de projection (18) d'une armoire (16) au moyen d'un dispositif d'introduction (32) une fois que la pièce à travailler (W) a atteint le flux descendant de la ligne de transport du transporteur à rouleaux d'entrée (12). La pièce à travailler (W) qui a été introduite dans la chambre de projection (18) est maintenue par un dispositif de serrage (34). Un projecteur projette un matériau de projection sur la pièce à travailler (W) qui est maintenue par le dispositif de serrage (34), puis ladite pièce à travailler (W) est évacuée sur un transporteur à rouleaux d'évacuation (52) au moyen d'un dispositif d'évacuation (56). Il est possible d'évacuer une pièce à travailler (W) de la chambre de projection (18) en même temps qu'une pièce à travailler (W) est introduite dans la chambre de projection (18) puisque le mécanisme situé sur le côté d'entrée et le mécanisme situé sur le côté de sortie sont séparés.
