Abstract
An adhesive bonded flexible abrasive finishing tool and method of making the same includes a cup-shape shank of plastic or metal. Flexible nylon abrasive loaded monofilaments of uniform length are formed into a cylindrical bundle. A measured amount of liquid instant cyanoacrylate adhesive is placed into the bottom of the cup portion of the shank and the bundle of monofilaments is driven as a group endwise by a pressure plate through a split funnel mounted on the lip of the cup so that one end of the bundle and thus each monofilament is driven uniformly into the adhesive which then cures rapidly. The monofilaments may preferably be straight or somewhat crimped or wavy and may vary in sectional configuration and abrasive loading. The resulting brush or finishing tool is a low cost light weight tool having improved distribution and density of filaments and a flat even face without a final trimming operation. The tool is ideally suited for automated or robotics finishing operations.
