Abstract
An abrasive flap brush including a central core, a layer of adhesive disposed on the peripheral surface of the core by a coater, and a plurality of abrasive flaps adhered to the core by the adhesive. The adhesive is uniformly distributed around the core by providing either the core or the adhesive coater with spacing projections that maintain a predetermined minimum distance between the coater and the core when the adhesive is applied. A coater including the spacing projections is also disclosed, as is a method for making an abrasive flap brush.

22. An abrasive flap brush of the type including a core having a layer of adhesive applied by the operative surface of a coater, said abrasive flap brush comprising:
-
a core including an outer surface; a layer of adhesive provided on said outer surface; and a plurality of abrasive flaps adhered to said core by said layer of adhesive; wherein said core includes spacing means on said outer surface for maintaining a predetermined minimum distance between said core outer surface and the operative surface of the coater thereby allowing a sufficiently uniform layer of said adhesive to be applied to said outer surface such that substantially all of said abrasive flaps are adhered to said core. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
