ABSTRACT:
An apparatus for abrading a curved surface includes a rotary wheel provided with a plurality of pins and a corresponding number of flexible members, wherein an endless sandpaper band is slidably wound about each pair of corresponding pins and flexible members. As the wheel rotates, the sandpaper bands abrade the workpiece in such a manner that each sandpaper band slides about its supporting pin and flexible member, thus presenting an ever-changing abrading surface to the workpiece. In a second embodiment, a plurality of rotary shafts are substituted for the pins, and driven through the same driving source as drives the rotary wheel so that a positive rotation is provided the sandpaper bands during the abrading process.
