Flap wheel
First Claim
1. An abrasive wheel for abrading a surface of a workpiece in accordance with a rotation of the wheel, including,a substantially rigid rotary member,first means extending radially from the rotary member and having an annular periphery at its outer radial end and having an annular rim at its outer radial periphery, the annular rim having a width extending axially beyond the first means to define opposite axial ends of the rim,a plurality of flaps each having an inner end and an outer end and each extending along the width of the rim and each extending from the annular rim at an angle relative to the annular rim and each disposed at least partially on an adjacent one of the flaps in an overlapping relationship in the radial direction with such adjacent ones of the flaps before the rotation of the wheel,the flaps being disposed around the complete periphery of the annular rim and being substantially parallel to one another in the overlapping relationship along the lengths of the flaps, andsecond means for attaching the flaps to the annular rim at the inner ends of the flaps along the width of the rim to retain the flaps in a substantially fixed relationship to one another and to the annular rim, with each flap disposed at the angle relative to the annular rim and with each flap disposed on an adjacent one of the flaps, during the rotation of the abrasive wheel and the application of the wheel against the workpiece surface.

Abstract
An abrasive wheel is partially defined by a support member and by a plurality of abrasive flaps on such member. A hole is disposed centrally in the support member to receive a mandrel for rotating the wheel. The support member has at its radial periphery an annular surface with a constant radius at progressive positions in the annular direction. The flaps are fixedly supported (as by epoxy) on the annular surface in a partially overlapping relationship between successive pairs of flaps. Each of the flaps has abrasive particles on one of its surfaces. Each of the flaps is disposed on the annular surface of the support member with the abrasive particles facing outwardly from such support surface. Each of the flaps defines an acute angle with the annular surface and extends at its opposite axial ends beyond the axial positions of support by such support surface. However, the flaps are fixedly positioned relative to one another even at the axial positions beyond the opposite axial ends of the annular surface on the support member as a result of the support by the support member and the overlapping relationship between the flaps in the successive pairs. In this way, the abrasive wheel is able to provide a positive and forceful action on a workpiece surface along the full axial width of the flaps when the abrasive wheel is rotated against the workpiece surface.
