ABSTRACT:
A flap-type rotary abrasive device comprising a plurality of leaves of flexible material, arranged in an annular array having a central bore. End caps having annular passageways are provided to seal the central bore. A predetermined amount of a settable securing material having a liquid and a solid state, such as epoxy, is injected while in a liquid state into the central bore of the array so that a portion of the injected material contacts the inner edges of the leaves and a portion is caused to flow between the leaf edges adjacent the annular passageways formed by the end caps. Upon setting or solidification, the securing material, in conjunction with the two end caps, provides a core in which the leaf inner edges are solidly and firmly secured.
