A multi-piece sanding wheel (5) having two sanding members (7) mounted about peripheral portions of a disc-shaped sup- port member (9) secured to a drive means (11). Each sanding member (7) includes a C-shaped backing portion (23) with a sand- ing strip (25) removably secured about its outer periphery. The sanding strip (25) also has two end sections (47) which are secured over ends (43) of the C-shape. The C-shaped backing portions (23) are attached to the disc-shaped support member (9) with ends (45) of the two C-shapes substantially adjacent to one another and pinching the end sections (47) of the sanding strips (25) there- between. The disc-shaped support member (9) is separately and removably attached to the drive means (11) wherein the sanding members (7) can be removed from the support member (9) without having to disconnect the support (9) member from the drive means (11). In this manner, the sanding strips (25) and backing portions (23) can both be easily and quickly removed and re- placed.

L'invention concerne une meule de ponçage multipièce (5) possédant deux éléments de ponçage (7) montés autour de parties périphériques d'un élément de support (9) de la forme d'un disque fixé à un moyen d'entraînement (11). Chaque élément de ponçage (7) comprend une partie arrière (23) profilée en C pourvue d'une bande de ponçage (25) fixée de manière amovible autour de sa périphérie externe. La bande de ponçage (25) possède également deux parties terminales (47) qui sont fixées sur les extrémités (43) de la partie profilée en C. Les parties arrière (23) profilées en C sont fixées à l'élément de support de la forme d'un disque (9), leurs extrémités (45) adjacentes l'une à l'autre serrant entre elles les parties terminales (47) des bandes de ponçage (25). L'élément support (9) de la forme d'un disque est fixé séparément et de manière amovible au moyen d'entraînement (11). Les éléments de ponçage (7) peuvent être retirés de l'élément de support (9) sans avoir à détacher celui-ci (9) du moyen d'entraînement (11). De cette façon, les bandes de ponçage (25) et les parties arrière (23) peuvent être, en même temps, facilement et rapidement retirées et remplacées.
