A flap wheel (1) for satin finishing systems for pipes or for sheet metal, includes a plurality of radial flaps (2) fixed to the hub (3) of the flap wheel (1) by coupling elements integral with the hub (3) of the flap wheel (1) and inserted in seats (8) formed in each flap (2) near the edge (14) thereof adjacent the hub (3). The hub (3) is advantageously hollow and has, in its inside wall, annular grooves (10) which are identical and parallel each other; the flaps (2) are further connected to the hub (3) by gluing, pouring inside the hub (3) an adhesive which flows out through a plurality of rows of through holes (9) formed in the wall of the hub (3) to coinciding with the annular grooves (10). A method of producing the flap wheel is also described.
A flap wheel (1), in particular a flap wheel for satin finishing systems for pipes or for sheet metal, comprising a plurality of radial flaps (2) fixed to a hub (3) and placed between two side flanges (4), characterised in that the radial flaps (2) are fixed to the hub (3) of the flap wheel (1) by means of coupling means (6, 16) integral with the hub (3) of the flap wheel (1) and inserted in seats (8) formed in each flap (2) near the edge (14) thereof adjacent to the hub (3).
