<p>The invention concerns a surface treatment device for: sanding, polishing, glossing planar or slightly convex surfaces, whether large or small in size. The device consists of a drive roller (1) which drives at least three sanding platens (2) integral with a disc (3) mounted idling. The disc (3) is driven in rotation under the effect of the rotation of the platens (2). The brake (5) slows down the movement. The arms of the sanding trays (2) tensed with springs (6) provide contact with the drive roller (1) imparting movement to the platens (2). The inventive device is particularly designed to treat planar or slightly convex surfaces.</p> |
