Abstract

L'invention concerne un corps de retenue (300, 300a) pour un produit abrasif (400), en particulier un disque de meulage (220), comprenant une couche de fixation (302) dotée d'une surface de fixation (305) comportant des moyens de fixation (306) et destinée à fixer un produit abrasif flexible (400), et un corps d'appui (301) doté d'une surface d'appui (303) soutenant une surface de retenue (304) de la couche de fixation (302), opposée en particulier à la surface de fixation (305), ladite surface d'appui étant en particulier reliée à ladite surface de retenue. Le corps d'appui (301) est perméable à l'air et à la poussière, il est constitué en particulier d'un matériau perméable à l'air et à la poussière (312). La couche de fixation (302) est réalisée de sorte que la surface de fixation (305) soit sensiblement perméable à l'air et à la poussière dans une direction (308) s'étendant sensiblement perpendiculairement à la surface de fixation (305), de sorte qu'un courant d'air (31) puisse sortir de la surface de fixation (305) sensiblement perpendiculairement à la surface de fixation (305) et pénétrer à travers la couche de fixation (302).
