  • Patent number: 4277917
    Abstract: A sanding, polishing and buffing wheel comprises a housing having a plurality of longitudinally extending, circumferentially spaced, slots. Each slot is differentially spaced with respect to the adjacent leading and trailing slots, having regard for the direction of wheel rotation in use. Threaded through each of a plurality of widely spaced slots in the end of a separate strip of abrasively surfaced material, the remainder of the extended length of which is anchored to a non-radial fin on a spool and wrapped around the spool in the initial loading thereof within the housing. The spool is normally fixed and can, when necessary, be released and rotated relative to the housing to loosen the wrapping of the strip material and then fixed. Thereafter, on rotation of the wheel for application to a work piece, the outer portions of the strips will automatically feed out through the respective slots to effect a desired length of their projected end portions.
